You can always assign a pod security policy (PSP) to an existing project if you didn't assign one during creation.
|
||||
|
||||
### Prerequisites
|
||||
|
||||
- Create a Pod Security Policy within Rancher. Before you can assign a default PSP to an existing project, you must have a PSP available for assignment. For instruction, see [Creating Pod Security Policies](../../new-user-guides/authentication-permissions-and-global-configuration/create-pod-security-policies.md).
|
||||
- Assign a default Pod Security Policy to the project's cluster. You can't assign a PSP to a project until one is already applied to the cluster. For more information, see [the documentation about adding a pod security policy to a cluster](../../new-user-guides/manage-clusters/add-a-pod-security-policy.md).
|
||||
|
||||
### Applying a Pod Security Policy
|
||||
|
||||
1. In the upper left corner, click **☰ > Cluster Management**.
|
||||
1. On the **Clusters** page, go to the cluster where you want to move a namespace and click **Explore**.
|
||||
1. Click **Cluster > Projects/Namespaces**.
|
||||
1. Find the project that you want to add a PSP to. From that project, select **⋮ > Edit Config**.
|
||||
1. From the **Pod Security Policy** drop-down, select the PSP you want to apply to the project.
|
||||
Assigning a PSP to a project will:
|
||||
|
||||
- Override the cluster's default PSP.
|
||||
- Apply the PSP to the project.
|
||||
- Apply the PSP to any namespaces you add to the project later.
|
||||
|
||||
1. Click **Save**.
|
||||
|
||||
**Result:** The PSP is applied to the project and any namespaces added to the project.
|
||||
|
||||
:::note
|
||||
|
||||
Any workloads that are already running in a cluster or project before a PSP is assigned will not be checked to determine if they comply with the PSP. Workloads would need to be cloned or upgraded to see if they pass the PSP.

## Pod Security Policies
|
||||
|
||||
_Pod Security Policies_ (or PSPs) are objects that control security-sensitive aspects of pod specification, e.g. root privileges. If a pod does not meet the conditions specified in the PSP, Kubernetes will not allow it to start, and Rancher will display an error message.
|
||||

||||

|
||||
|
||||
[Pod Security Policies (PSPs)](https://kubernetes.io/docs/concepts/security/pod-security-policy/) are objects that control security-sensitive aspects of the pod specification (such as root privileges).
|
||||
|
||||
If a pod doesn't meet the conditions specified in the PSP, Kubernetes won't allow it to start, and Rancher will display the following error message: `Pod <NAME> is forbidden: unable to validate...`.
|
||||
|
||||
|
||||
## How PSPs Work
|
||||
|
||||
You can assign PSPs at the cluster or project level.
|
||||
|
||||
PSPs work through inheritance:
|
||||
|
||||
- By default, PSPs assigned to a cluster are inherited by its projects, as well as any namespaces added to those projects.
|
||||
- **Exception:** Namespaces that are not assigned to projects do not inherit PSPs, regardless of whether the PSP is assigned to a cluster or project. Because these namespaces have no PSPs, workload deployments to these namespaces will fail, which is the default Kubernetes behavior.
|
||||
- You can override the default PSP by assigning a different PSP directly to the project.
|
||||
|
||||
Any workloads that are already running in a cluster or project before a PSP is assigned will not be checked if it complies with the PSP. Workloads would need to be cloned or upgraded to see if they pass the PSP.
|
||||
|
||||
Read more about Pod Security Policies in the [Kubernetes documentation](https://kubernetes.io/docs/concepts/policy/pod-security-policy/).
|
||||
|
||||
## Default PSPs
|
||||
|
||||
Rancher ships with three default Pod Security Policies (PSPs): the `restricted-noroot`, `restricted` and `unrestricted` policies.
|
||||
|
||||
### Restricted-NoRoot
|
||||
|
||||
This policy is based on the Kubernetes [example restricted policy](https://raw.githubusercontent.com/kubernetes/website/master/content/en/examples/policy/restricted-psp.yaml). It significantly restricts what types of pods can be deployed to a cluster or project. This policy:
|
||||
|
||||
- Prevents pods from running as a privileged user and prevents escalation of privileges.
|
||||
- Validates that server-required security mechanisms are in place, such as restricting what volumes can be mounted to only the core volume types and preventing root supplemental groups from being added.
|
||||
|
||||
### Restricted
|
||||
|
||||
This policy is a relaxed version of the `restricted-noroot` policy, with almost all the restrictions in place, except for the fact that it allows running containers as a privileged user.
|
||||
|
||||
### Unrestricted
|
||||
|
||||
This policy is equivalent to running Kubernetes with the PSP controller disabled. It has no restrictions on what pods can be deployed into a cluster or project.
|
||||
|
||||
:::note important
|
||||
|
||||
When disabling PSPs, default PSPs are **not** automatically deleted from your cluster. You must manually delete them if they're no longer needed.
|
||||
|
||||
:::
|
||||
|
||||
## Creating PSPs
|
||||
|
||||
Using Rancher, you can create a Pod Security Policy using our GUI rather than creating a YAML file.
|
||||
|
||||
### Requirements
|
||||
|
||||
Rancher can only assign PSPs for clusters that are [launched using RKE](../launch-kubernetes-with-rancher/launch-kubernetes-with-rancher.md).
|
||||
|
||||
You must enable PSPs at the cluster level before you can assign them to a project. This can be configured by [editing the cluster](../../../reference-guides/cluster-configuration/cluster-configuration.md).
|
||||
|
||||
It is a best practice to set PSP at the cluster level.
|
||||
|
||||
We recommend adding PSPs during cluster and project creation instead of adding it to an existing one.
|
||||
|
||||
### Creating PSPs in the Rancher UI
|
||||
|
||||
1. In the upper left corner, click **☰ > Cluster Management**.
|
||||
1. In the left navigation bar, click **Pod Security Policies**.
|
||||
1. Click **Add Policy**.

||||

## Upgrade to Pod Security Standards (PSS)
|
||||
|
||||
Ensure that you migrate all PSPs to another workload security mechanism. This includes mapping your current PSPs to Pod Security Standards for enforcement with the [PSA controller](https://kubernetes.io/docs/concepts/security/pod-security-admission/). If the PSA controller won't meet all of your organization's needs, we recommend that you use a policy engine, such as [Kubewarden](https://www.kubewarden.io/), [Kyverno](https://kyverno.io/), or [NeuVector](https://neuvector.com/). Refer to the documentation of your policy engine of choice for more information on how to migrate from PSPs.
|
||||
|
||||
:::caution
|
||||
You must add your new policy enforcement mechanisms _before_ you remove the PodSecurityPolicy objects. If you don't, you may create an opportunity for privilege escalation attacks within the cluster.

|
||||
|
||||
### Removing PodSecurityPolicies from Rancher-Maintained Apps & Marketplace Workloads
|
||||
|
||||
Rancher v2.7.2 offers a new major version of Rancher-maintained Helm charts. v102.x.y allows you to remove PSPs that were installed with previous versions of the chart. This new version replaces non-standard PSPs switches with the standardized `global.cattle.psp.enabled` switch, which is turned off by default.
|
||||
|
||||
You must perform the following steps _while still in Kubernetes v1.24_:
|
||||
1. Configure the PSA controller to suit your needs. You can use one of Rancher's built-in [PSA Configuration Templates](#pod-security-admission-configuration-templates), or create a custom template and apply it to the clusters that you are migrating.
|
||||
|
||||
1. Map your active PSPs to Pod Security Standards:

```
|
||||
|
||||
1. Follow the Kubernetes guide on [Mapping PSPs to Pod Security Standards](https://kubernetes.io/docs/reference/access-authn-authz/psp-to-pod-security-standards/) to apply PSSs to your workloads that were relying on PSPs. See [Migrate from PodSecurityPolicy to the Built-In PodSecurity Admission controller](https://kubernetes.io/docs/tasks/configure-pod-container/migrate-from-psp/) for more details.
|
||||
|
||||
1. To remove PSPs from Rancher charts, upgrade the charts to the latest v102.x.y version _before_ you upgrade to Kubernetes v1.25. Make sure that the **Enable PodSecurityPolicies** option is **disabled**. This will remove any PSPs that were installed with previous chart versions.
|
||||
|
||||
:::info important
|
||||
If you want to upgrade your charts to v102.x.y, but don't plan on upgrading your clusters to Kubernetes v1.25 and moving away from PSPs, make sure that you select the option **Enable PodSecurityPolicies** for each chart that you are upgrading.

### Cleaning Up Releases After a Kubernetes v1.25 Upgrade
|
||||
|
||||
If you experience problems while removing PSPs from your charts, or have charts that don't contain a built-in mechanism for removing PSPs, your chart upgrades or deletions might fail with an error message such as the following:
|
||||
```console
|
||||
Error: UPGRADE FAILED: resource mapping not found for name: "<object-name>" namespace: "<object-namespace>" from "": no matches for kind "PodSecurityPolicy" in version "policy/v1beta1"
|
||||
ensure CRDs are installed first
|
||||
```
|
||||
|
||||
This happens when Helm tries to query the cluster for objects that were stored in a previous release's data blob. To clean up these releases and avoid this error, use the `helm-mapkubeapis` Helm plugin. To learn more about `helm-mapkubeapis`, how it works, and how it can be fine-tuned for your use case, see the [official Helm documentation](https://github.com/helm/helm-mapkubeapis#readme).
|
||||
|
||||
Note that Helm plugin installation is local to the machine that you run the commands from. Therefore, make sure that you run both the installation and cleanup from the same machine.

When your cluster is running pods with security-sensitive configurations, assign it a [pod security policy](../authentication-permissions-and-global-configuration/create-pod-security-policies.md), which is a set of rules that monitors the conditions and settings in your pods. If a pod doesn't meet the rules specified in your policy, the policy stops it from running.
|
||||
|
||||
You can assign a pod security policy when you provision a cluster. However, if you need to relax or restrict security for your pods later, you can update the policy while editing your cluster.

1. Click **☰ > Cluster Management**.

If you have restrictive Pod Security Policies enabled, then Istio may not be able to function correctly, because it needs certain permissions in order to install itself and manage pod infrastructure. In this section, we will configure a cluster with PSPs enabled for an Istio install, and also set up the Istio CNI plugin.
|
||||
|
||||
The Istio CNI plugin removes the need for each application pod to have a privileged `NET_ADMIN` container. For further information, see the [Istio CNI Plugin docs](https://istio.io/docs/setup/additional-setup/cni). Please note that the [Istio CNI Plugin is in alpha](https://istio.io/about/feature-stages/).

|
||||
- The cluster must be an RKE Kubernetes cluster.
|
||||
- The cluster must have been created with a default PodSecurityPolicy.
|
||||
|
||||
To enable pod security policy support when creating a Kubernetes cluster in the Rancher UI, go to <b>Advanced Options.</b> In the <b>Pod Security Policy Support</b> section, click <b>Enabled.</b> Then select a default pod security policy.

### 1. Set the PodSecurityPolicy to unrestricted
|
||||
|
||||
An unrestricted PSP allows Istio to be installed.
|

|
||||
|
||||
When installing or upgrading Istio through **Apps,**
|
||||
|
||||
1. Click **Components**.
|
||||
2. Check the box next to **Enabled CNI**.
|
||||
3. Finish installing or upgrading Istio.
|
||||
|
||||
The CNI can also be enabled by editing the `values.yaml`:
|
||||
|
||||
```
|
||||
istio_cni.enabled: true
|
||||
```
|
||||
|
||||
Istio should install successfully with the CNI enabled in the cluster.
|
||||
|
||||
### 3. Verify that the CNI is working
|
||||
|

You can always assign a pod security policy (PSP) to an existing project if you didn't assign one during creation.
|
||||
|
||||
### Prerequisites
|
||||
|
||||
- Create a Pod Security Policy within Rancher. Before you can assign a default PSP to an existing project, you must have a PSP available for assignment. For instruction, see [Creating Pod Security Policies](../../new-user-guides/authentication-permissions-and-global-configuration/create-pod-security-policies.md).
|
||||
- Assign a default Pod Security Policy to the project's cluster. You can't assign a PSP to a project until one is already applied to the cluster. For more information, see [the documentation about adding a pod security policy to a cluster](../../new-user-guides/manage-clusters/add-a-pod-security-policy.md).
|
||||
|
||||
### Applying a Pod Security Policy
|
||||
|
||||
1. In the upper left corner, click **☰ > Cluster Management**.
|
||||
1. On the **Clusters** page, go to the cluster where you want to move a namespace and click **Explore**.
|
||||
1. Click **Cluster > Projects/Namespaces**.
|
||||
1. Find the project that you want to add a PSP to. From that project, select **⋮ > Edit Config**.
|
||||
1. From the **Pod Security Policy** drop-down, select the PSP you want to apply to the project.
|
||||
Assigning a PSP to a project will:
|
||||
|
||||
- Override the cluster's default PSP.
|
||||
- Apply the PSP to the project.
|
||||
- Apply the PSP to any namespaces you add to the project later.
|
||||
|
||||
1. Click **Save**.
|
||||
|
||||
**Result:** The PSP is applied to the project and any namespaces added to the project.

||||
|
||||
:::note
|
||||
|
||||
Any workloads that are already running in a cluster or project before a PSP is assigned will not be checked to determine if they comply with the PSP. Workloads would need to be cloned or upgraded to see if they pass the PSP.

## Pod Security Policies
|
||||
|
||||
_Pod Security Policies_ (or PSPs) are objects that control security-sensitive aspects of pod specification, e.g. root privileges. If a pod does not meet the conditions specified in the PSP, Kubernetes will not allow it to start, and Rancher will display an error message.
|
||||

||||

:::
|
||||
|
||||
[Pod Security Policies (PSPs)](https://kubernetes.io/docs/concepts/security/pod-security-policy/) are objects that control security-sensitive aspects of the pod specification (such as root privileges).
|
||||
|
||||
If a pod doesn't meet the conditions specified in the PSP, Kubernetes won't allow it to start, and Rancher will display the following error message: `Pod <NAME> is forbidden: unable to validate...`.
|
||||
|
||||
|
||||
## How PSPs Work
|
||||
|
||||
You can assign PSPs at the cluster or project level.
|
||||
|
||||
PSPs work through inheritance:
|
||||
|
||||
- By default, PSPs assigned to a cluster are inherited by its projects, as well as any namespaces added to those projects.
|
||||
- **Exception:** Namespaces that are not assigned to projects do not inherit PSPs, regardless of whether the PSP is assigned to a cluster or project. Because these namespaces have no PSPs, workload deployments to these namespaces will fail, which is the default Kubernetes behavior.
|
||||
- You can override the default PSP by assigning a different PSP directly to the project.
|
||||
|
||||
Any workloads that are already running in a cluster or project before a PSP is assigned will not be checked if it complies with the PSP. Workloads would need to be cloned or upgraded to see if they pass the PSP.
|
||||
|
||||
Read more about Pod Security Policies in the [Kubernetes documentation](https://kubernetes.io/docs/concepts/policy/pod-security-policy/).
|
||||
|
||||
## Default PSPs
|
||||
|
||||
Rancher ships with three default Pod Security Policies (PSPs): the `restricted-noroot`, `restricted` and `unrestricted` policies.
|
||||
|
||||
### Restricted-NoRoot
|
||||
|
||||
This policy is based on the Kubernetes [example restricted policy](https://raw.githubusercontent.com/kubernetes/website/master/content/en/examples/policy/restricted-psp.yaml). It significantly restricts what types of pods can be deployed to a cluster or project. This policy:
|
||||
|
||||
- Prevents pods from running as a privileged user and prevents escalation of privileges.
|
||||
- Validates that server-required security mechanisms are in place, such as restricting what volumes can be mounted to only the core volume types and preventing root supplemental groups from being added.
|
||||
|
||||
### Restricted
|
||||
|
||||
This policy is a relaxed version of the `restricted-noroot` policy, with almost all the restrictions in place, except for the fact that it allows running containers as a privileged user.
|
||||
|
||||
### Unrestricted
|
||||
|
||||
This policy is equivalent to running Kubernetes with the PSP controller disabled. It has no restrictions on what pods can be deployed into a cluster or project.
|
||||
|
||||
:::note important
|
||||
|
||||
When disabling PSPs, default PSPs are **not** automatically deleted from your cluster. You must manually delete them if they're no longer needed.
|
||||
|
||||
:::
|
||||
|
||||
## Creating PSPs
|
||||
|
||||
Using Rancher, you can create a Pod Security Policy using our GUI rather than creating a YAML file.
|
||||
|
||||
### Requirements
|
||||
|
||||
Rancher can only assign PSPs for clusters that are [launched using RKE](../launch-kubernetes-with-rancher/launch-kubernetes-with-rancher.md).
|
||||
|
||||
You must enable PSPs at the cluster level before you can assign them to a project. This can be configured by [editing the cluster](../../../reference-guides/cluster-configuration/cluster-configuration.md).
|
||||
|
||||
It is a best practice to set PSP at the cluster level.
|
||||
|
||||
We recommend adding PSPs during cluster and project creation instead of adding it to an existing one.
|
||||
|
||||
### Creating PSPs in the Rancher UI
|
||||
|
||||
1. In the upper left corner, click **☰ > Cluster Management**.
|
||||
1. In the left navigation bar, click **Pod Security Policies**.

## Upgrade to Pod Security Standards (PSS)
|
||||
|
||||
Ensure that you migrate all PSPs to another workload security mechanism. This includes mapping your current PSPs to Pod Security Standards for enforcement with the [PSA controller](https://kubernetes.io/docs/concepts/security/pod-security-admission/). If the PSA controller won't meet all of your organization's needs, we recommend that you use a policy engine, such as [Kubewarden](https://www.kubewarden.io/), [Kyverno](https://kyverno.io/), or [NeuVector](https://neuvector.com/). Refer to the documentation of your policy engine of choice for more information on how to migrate from PSPs.
|
||||
|
||||
:::caution
|
||||
You must add your new policy enforcement mechanisms _before_ you remove the PodSecurityPolicy objects. If you don't, you may create an opportunity for privilege escalation attacks within the cluster.

|
||||
### Removing PodSecurityPolicies from Rancher-Maintained Apps & Marketplace Workloads
|
||||
|
||||
Rancher v2.7.2 offers a new major version of Rancher-maintained Helm charts. v102.x.y allows you to remove PSPs that were installed with previous versions of the chart. This new version replaces non-standard PSPs switches with the standardized `global.cattle.psp.enabled` switch, which is turned off by default.
|
||||
|
||||
You must perform the following steps _while still in Kubernetes v1.24_:
|
||||
1. Configure the PSA controller to suit your needs. You can use one of Rancher's built-in [PSA Configuration Templates](#pod-security-admission-configuration-templates), or create a custom template and apply it to the clusters that you are migrating.

||||

|
||||
|
||||
1. Follow the Kubernetes guide on [Mapping PSPs to Pod Security Standards](https://kubernetes.io/docs/reference/access-authn-authz/psp-to-pod-security-standards/) to apply PSSs to your workloads that were relying on PSPs. See [Migrate from PodSecurityPolicy to the Built-In PodSecurity Admission controller](https://kubernetes.io/docs/tasks/configure-pod-container/migrate-from-psp/) for more details.
|
||||
|
||||
1. To remove PSPs from Rancher charts, upgrade the charts to the latest v102.x.y version _before_ you upgrade to Kubernetes v1.25. Make sure that the **Enable PodSecurityPolicies** option is **disabled**. This will remove any PSPs that were installed with previous chart versions.

||||
|
||||
:::info important
|
||||
If you want to upgrade your charts to v102.x.y, but don't plan on upgrading your clusters to Kubernetes v1.25 and moving away from PSPs, make sure that you select the option **Enable PodSecurityPolicies** for each chart that you are upgrading.

### Cleaning Up Releases After a Kubernetes v1.25 Upgrade
|
||||
|
||||
If you experience problems while removing PSPs from your charts, or have charts that don't contain a built-in mechanism for removing PSPs, your chart upgrades or deletions might fail with an error message such as the following:
|
||||
```console
|
||||
Error: UPGRADE FAILED: resource mapping not found for name: "<object-name>" namespace: "<object-namespace>" from "": no matches for kind "PodSecurityPolicy" in version "policy/v1beta1"

||||
```
|
||||
|

This happens when Helm tries to query the cluster for objects that were stored in a previous release's data blob. To clean up these releases and avoid this error, use the `helm-mapkubeapis` Helm plugin.

_Pod Security Policies_ are objects that control security-sensitive aspects of pod specification (like root privileges).
|
||||
|
||||
## Adding a Default Pod Security Policy
|
||||
|
||||
When you create a new cluster with RKE, you can configure it to apply a PSP immediately. As you create the cluster, use the **Cluster Options** to enable a PSP. The PSP assigned to the cluster will be the default PSP for projects within the cluster.
|
||||
|
||||
:::note Prerequisite:
|
||||
|
||||
Create a Pod Security Policy within Rancher. Before you can assign a default PSP to a new cluster, you must have a PSP available for assignment. For instruction, see [Creating Pod Security Policies](../authentication-permissions-and-global-configuration/create-pod-security-policies.md).

|

|

For security purposes, we recommend assigning a PSP as you create your clusters.
|
||||
|
||||
:::
|
||||
|
||||
To enable a default Pod Security Policy, set the **Pod Security Policy Support** option to **Enabled**, and then make a selection from the **Default Pod Security Policy** drop-down.
|
||||
|
||||
When the cluster finishes provisioning, the PSP you selected is applied to all projects within the cluster.

If you have restrictive Pod Security Policies enabled, then Istio may not be able to function correctly, because it needs certain permissions in order to install itself and manage pod infrastructure. In this section, we will configure a cluster with PSPs enabled for an Istio install, and also set up the Istio CNI plugin.
|
||||
|
||||
The Istio CNI plugin removes the need for each application pod to have a privileged `NET_ADMIN` container. For further information, see the [Istio CNI Plugin docs](https://istio.io/docs/setup/additional-setup/cni). Please note that the [Istio CNI Plugin is in alpha](https://istio.io/about/feature-stages/).
|
||||
|
||||
:::note Prerequisites:
|
||||
|
||||
- The cluster must be an RKE Kubernetes cluster.
|
||||
- The cluster must have been created with a default PodSecurityPolicy.
|
||||
|
||||
To enable pod security policy support when creating a Kubernetes cluster in the Rancher UI, go to <b>Advanced Options.</b> In the <b>Pod Security Policy Support</b> section, click <b>Enabled.</b> Then select a default pod security policy.

|
||||
3. [Verify that the CNI is working.](#3-verify-that-the-cni-is-working)
|
||||
|
||||
### 1. Set the PodSecurityPolicy to unrestricted
|
||||
|
||||
An unrestricted PSP allows Istio to be installed.
|
||||
|
||||
Set the PSP to `unrestricted` in the project where is Istio is installed, or the project where you plan to install Istio.
|
||||
|
||||
1. Click **☰ > Cluster Management**.
|
||||
1. Go to the cluster that you created and click **Explore**.
|
||||
1. Click **Cluster > Projects/Namespaces**.
|
||||
1. Find the **Project: System** and select the **⋮ > Edit Config**.
|
||||
1. Change the Pod Security Policy option to be unrestricted, then click **Save**.
|
||||
|
||||
### 2. Enable the CNI
|
||||
|
||||
When installing or upgrading Istio through **Apps,**
|
||||
|
||||
1. Click **Components**.
|
||||
2. Check the box next to **Enabled CNI**.
|
||||
3. Finish installing or upgrading Istio.
|
||||
|
||||
The CNI can also be enabled by editing the `values.yaml`:
|
||||
|
||||
```
|
||||
istio_cni.enabled: true
|
||||
```
|
||||
|
||||
Istio should install successfully with the CNI enabled in the cluster.
|
||||
|
||||
### 3. Verify that the CNI is working
|
||||
|
||||
Verify that the CNI is working by deploying a [sample application](https://istio.io/latest/docs/examples/bookinfo/) or deploying one of your own applications.

You can always assign a pod security policy (PSP) to an existing project if you didn't assign one during creation.
|
||||
|
||||
### Prerequisites
|
||||
|
||||
- Create a Pod Security Policy within Rancher. Before you can assign a default PSP to an existing project, you must have a PSP available for assignment. For instruction, see [Creating Pod Security Policies](../../new-user-guides/authentication-permissions-and-global-configuration/create-pod-security-policies.md).
|
||||
- Assign a default Pod Security Policy to the project's cluster. You can't assign a PSP to a project until one is already applied to the cluster. For more information, see [the documentation about adding a pod security policy to a cluster](../../new-user-guides/manage-clusters/add-a-pod-security-policy.md).
|
||||
|
||||
### Applying a Pod Security Policy
|
||||
|
||||
1. In the upper left corner, click **☰ > Cluster Management**.
|
||||
1. On the **Clusters** page, go to the cluster where you want to move a namespace and click **Explore**.
|
||||
1. Click **Cluster > Projects/Namespaces**.
|
||||
1. Find the project that you want to add a PSP to. From that project, select **⋮ > Edit Config**.
|
||||
1. From the **Pod Security Policy** drop-down, select the PSP you want to apply to the project.
|
||||
Assigning a PSP to a project will:
|
||||
|
||||
- Override the cluster's default PSP.
|
||||
- Apply the PSP to the project.
|
||||
- Apply the PSP to any namespaces you add to the project later.
|
||||
|
||||
1. Click **Save**.
|
||||
|
||||
**Result:** The PSP is applied to the project and any namespaces added to the project.
|
||||
|
||||
:::note
|
||||
|
||||
Any workloads that are already running in a cluster or project before a PSP is assigned will not be checked to determine if they comply with the PSP. Workloads would need to be cloned or upgraded to see if they pass the PSP.

## Pod Security Policies
|
||||
|
||||
_Pod Security Policies_ (or PSPs) are objects that control security-sensitive aspects of pod specification, e.g. root privileges. If a pod does not meet the conditions specified in the PSP, Kubernetes will not allow it to start, and Rancher will display an error message.
|
||||
|
||||
For more information how to create and use PSPs, see [Pod Security Policies](create-pod-security-policies.md).
|
||||
|
||||
## Provisioning Drivers
|
||||
|
||||
Drivers in Rancher allow you to manage which providers can be used to provision [hosted Kubernetes clusters](../kubernetes-clusters-in-rancher-setup/set-up-clusters-from-hosted-kubernetes-providers/set-up-clusters-from-hosted-kubernetes-providers.md) or [nodes in an infrastructure provider](../launch-kubernetes-with-rancher/use-new-nodes-in-an-infra-provider/use-new-nodes-in-an-infra-provider.md) to allow Rancher to deploy and manage Kubernetes.

:::
|
||||
|
||||
[Pod Security Policies (PSPs)](https://kubernetes.io/docs/concepts/security/pod-security-policy/) are objects that control security-sensitive aspects of the pod specification (such as root privileges).
|
||||
|
||||
If a pod doesn't meet the conditions specified in the PSP, Kubernetes won't allow it to start, and Rancher will display the following error message: `Pod <NAME> is forbidden: unable to validate...`.
|
||||
|
||||
|
||||
## How PSPs Work
|
||||
|
||||
You can assign PSPs at the cluster or project level.
|
||||
|
||||
PSPs work through inheritance:
|
||||
|
||||
- By default, PSPs assigned to a cluster are inherited by its projects, as well as any namespaces added to those projects.
|
||||
- **Exception:** Namespaces that are not assigned to projects do not inherit PSPs, regardless of whether the PSP is assigned to a cluster or project. Because these namespaces have no PSPs, workload deployments to these namespaces will fail, which is the default Kubernetes behavior.
|
||||
- You can override the default PSP by assigning a different PSP directly to the project.
|
||||
|
||||
Any workloads that are already running in a cluster or project before a PSP is assigned will not be checked if it complies with the PSP. Workloads would need to be cloned or upgraded to see if they pass the PSP.
|
||||
|
||||
Read more about Pod Security Policies in the [Kubernetes documentation](https://kubernetes.io/docs/concepts/policy/pod-security-policy/).
|
||||
|
||||
## Default PSPs
|
||||
|
||||
Rancher ships with three default Pod Security Policies (PSPs): the `restricted-noroot`, `restricted` and `unrestricted` policies.
|
||||
|
||||
### Restricted-NoRoot
|
||||
|
||||
This policy is based on the Kubernetes [example restricted policy](https://raw.githubusercontent.com/kubernetes/website/master/content/en/examples/policy/restricted-psp.yaml). It significantly restricts what types of pods can be deployed to a cluster or project. This policy:
|
||||
|
||||
- Prevents pods from running as a privileged user and prevents escalation of privileges.
|
||||
- Validates that server-required security mechanisms are in place, such as restricting what volumes can be mounted to only the core volume types and preventing root supplemental groups from being added.
|
||||
|
||||
### Restricted
|
||||
|
||||
This policy is a relaxed version of the `restricted-noroot` policy, with almost all the restrictions in place, except for the fact that it allows running containers as a privileged user.
|
||||
|
||||
### Unrestricted
|
||||
|
||||
This policy is equivalent to running Kubernetes with the PSP controller disabled. It has no restrictions on what pods can be deployed into a cluster or project.
|
||||
|
||||
:::note important
|
||||
|
||||
When disabling PSPs, default PSPs are **not** automatically deleted from your cluster. You must manually delete them if they're no longer needed.
|
||||
|
||||
:::
|
||||
|
||||
## Creating PSPs
|
||||
|
||||
Using Rancher, you can create a Pod Security Policy using our GUI rather than creating a YAML file.
|
||||
|
||||
### Requirements
|
||||
|
||||
Rancher can only assign PSPs for clusters that are [launched using RKE](../launch-kubernetes-with-rancher/launch-kubernetes-with-rancher.md).
|
||||
|
||||
You must enable PSPs at the cluster level before you can assign them to a project. This can be configured by [editing the cluster](../../../reference-guides/cluster-configuration/cluster-configuration.md).
|
||||
|
||||
It is a best practice to set PSP at the cluster level.
|
||||
|
||||
We recommend adding PSPs during cluster and project creation instead of adding it to an existing one.
|
||||
|
||||
### Creating PSPs in the Rancher UI
|
||||
|
||||
1. In the upper left corner, click **☰ > Cluster Management**.
|
||||
1. In the left navigation bar, click **Pod Security Policies**.
|
||||
1. Click **Add Policy**.
|
||||

||||

||||
## Upgrade to Pod Security Standards (PSS)
|
||||
|
||||
Ensure that you migrate all PSPs to another workload security mechanism. This includes mapping your current PSPs to Pod Security Standards for enforcement with the [PSA controller](https://kubernetes.io/docs/concepts/security/pod-security-admission/). If the PSA controller won't meet all of your organization's needs, we recommend that you use a policy engine, such as [Kubewarden](https://www.kubewarden.io/), [Kyverno](https://kyverno.io/), or [NeuVector](https://neuvector.com/). Refer to the documentation of your policy engine of choice for more information on how to migrate from PSPs.
|
||||
|
||||
:::caution
|
||||
You must add your new policy enforcement mechanisms _before_ you remove the PodSecurityPolicy objects. If you don't, you may create an opportunity for privilege escalation attacks within the cluster.

|
||||
### Removing PodSecurityPolicies from Rancher-Maintained Apps & Marketplace Workloads
|
||||
|
||||
Rancher v2.7.2 offers a new major version of Rancher-maintained Helm charts. v102.x.y allows you to remove PSPs that were installed with previous versions of the chart. This new version replaces non-standard PSPs switches with the standardized `global.cattle.psp.enabled` switch, which is turned off by default.
|
||||
|
||||
You must perform the following steps _while still in Kubernetes v1.24_:
|
||||
1. Configure the PSA controller to suit your needs. You can use one of Rancher's built-in [PSA Configuration Templates](#pod-security-admission-configuration-templates), or create a custom template and apply it to the clusters that you are migrating.
|
||||
|
||||

|
||||
| tr " " "\n" | sort -u
|
||||
```
|
||||
|
||||
1. Follow the Kubernetes guide on [Mapping PSPs to Pod Security Standards](https://kubernetes.io/docs/reference/access-authn-authz/psp-to-pod-security-standards/) to apply PSSs to your workloads that were relying on PSPs. See [Migrate from PodSecurityPolicy to the Built-In PodSecurity Admission controller](https://kubernetes.io/docs/tasks/configure-pod-container/migrate-from-psp/) for more details.
|
||||
|
||||
1. To remove PSPs from Rancher charts, upgrade the charts to the latest v102.x.y version _before_ you upgrade to Kubernetes v1.25. Make sure that the **Enable PodSecurityPolicies** option is **disabled**. This will remove any PSPs that were installed with previous chart versions.
|
||||
|
||||
:::info important
|
||||
If you want to upgrade your charts to v102.x.y, but don't plan on upgrading your clusters to Kubernetes v1.25 and moving away from PSPs, make sure that you select the option **Enable PodSecurityPolicies** for each chart that you are upgrading.

### Cleaning Up Releases After a Kubernetes v1.25 Upgrade
|
||||
|
||||
If you experience problems while removing PSPs from your charts, or have charts that don't contain a built-in mechanism for removing PSPs, your chart upgrades or deletions might fail with an error message such as the following:
|
||||
```console
|
||||
Error: UPGRADE FAILED: resource mapping not found for name: "<object-name>" namespace: "<object-namespace>" from "": no matches for kind "PodSecurityPolicy" in version "policy/v1beta1"
|
||||

|
||||
```
|
||||
|
||||
This happens when Helm tries to query the cluster for objects that were stored in a previous release's data blob. To clean up these releases and avoid this error, use the `helm-mapkubeapis` Helm plugin. To learn more about `helm-mapkubeapis`, how it works, and how it can be fine-tuned for your use case, see the [official Helm documentation](https://github.com/helm/helm-mapkubeapis#readme).

[Rancher-Istio](https://github.com/rancher/charts/tree/release-v2.11/charts/rancher-istio) will be deprecated in Rancher v2.12.0; turn to the [SUSE Rancher Application Collection](https://apps.rancher.io) build of Istio for enhanced security (included in SUSE Rancher Prime subscriptions).
|
||||
|
||||
Detailed information can be found in [this announcement](https://forums.suse.com/t/deprecation-of-rancher-istio/45043).
|
||||
|
||||
:::
|
||||
|
||||
If you have restrictive Pod Security Policies enabled, then Istio may not be able to function correctly, because it needs certain permissions in order to install itself and manage pod infrastructure. In this section, we will configure a cluster with PSPs enabled for an Istio install, and also set up the Istio CNI plugin.
|
||||
|
||||
The Istio CNI plugin removes the need for each application pod to have a privileged `NET_ADMIN` container. For further information, see the [Istio CNI Plugin docs](https://istio.io/docs/setup/additional-setup/cni). Please note that the [Istio CNI Plugin is in alpha](https://istio.io/about/feature-stages/).
|
||||
|
||||
:::note Prerequisites:
|
||||
|
||||
- The cluster must be an RKE Kubernetes cluster.
|
||||
- The cluster must have been created with a default PodSecurityPolicy.
|
||||
|
||||
To enable pod security policy support when creating a Kubernetes cluster in the Rancher UI, go to <b>Advanced Options.</b> In the <b>Pod Security Policy Support</b> section, click <b>Enabled.</b> Then select a default pod security policy.
|
||||
|
||||

||||
1. [Set the PodSecurityPolicy to unrestricted](#1-set-the-podsecuritypolicy-to-unrestricted)
|
||||
2. [Enable the CNI](#2-enable-the-cni)
|
||||
3. [Verify that the CNI is working.](#3-verify-that-the-cni-is-working)
|
||||
|
||||
### 1. Set the PodSecurityPolicy to unrestricted
|
||||
|
||||
An unrestricted PSP allows Istio to be installed.
|
||||
|
||||
Set the PSP to `unrestricted` in the project where is Istio is installed, or the project where you plan to install Istio.
|
||||
|
||||
1. Click **☰ > Cluster Management**.
|
||||
1. Go to the cluster that you created and click **Explore**.
|
||||
1. Click **Cluster > Projects/Namespaces**.
|
||||
1. Find the **Project: System** and select the **⋮ > Edit Config**.
|
||||
1. Change the Pod Security Policy option to be unrestricted, then click **Save**.
|
||||
|
||||
### 2. Enable the CNI
|
||||
|
||||
When installing or upgrading Istio through **Apps,**
|
||||
|
||||
1. Click **Components**.
|
||||
2. Check the box next to **Enabled CNI**.
|
||||
3. Finish installing or upgrading Istio.
|
||||
|
||||
The CNI can also be enabled by editing the `values.yaml`:
|
||||
|
||||
```
|
||||
istio_cni.enabled: true
|
||||
```
|
||||
|
||||
Istio should install successfully with the CNI enabled in the cluster.
|
||||
|
||||
### 3. Verify that the CNI is working
|
||||
|
||||
Verify that the CNI is working by deploying a [sample application](https://istio.io/latest/docs/examples/bookinfo/) or deploying one of your own applications.

You can always assign a pod security policy (PSP) to an existing project if you didn't assign one during creation.
|
||||
|
||||
### Prerequisites
|
||||
|
||||
- Create a Pod Security Policy within Rancher. Before you can assign a default PSP to an existing project, you must have a PSP available for assignment. For instruction, see [Creating Pod Security Policies](../../new-user-guides/authentication-permissions-and-global-configuration/create-pod-security-policies.md).
|
||||
- Assign a default Pod Security Policy to the project's cluster. You can't assign a PSP to a project until one is already applied to the cluster. For more information, see [the documentation about adding a pod security policy to a cluster](../../new-user-guides/manage-clusters/add-a-pod-security-policy.md).
|
||||
|
||||
### Applying a Pod Security Policy
|
||||
|
||||
1. In the upper left corner, click **☰ > Cluster Management**.
|
||||
1. On the **Clusters** page, go to the cluster where you want to move a namespace and click **Explore**.
|
||||
1. Click **Cluster > Projects/Namespaces**.
|
||||
1. Find the project that you want to add a PSP to. From that project, select **⋮ > Edit Config**.
|
||||
1. From the **Pod Security Policy** drop-down, select the PSP you want to apply to the project.
|
||||
Assigning a PSP to a project will:
|
||||
|
||||
- Override the cluster's default PSP.
|
||||
- Apply the PSP to the project.
|
||||
- Apply the PSP to any namespaces you add to the project later.
|
||||
|
||||
1. Click **Save**.
|
||||
|
||||
**Result:** The PSP is applied to the project and any namespaces added to the project.
|
||||
|
||||
:::note
|
||||
|
||||
Any workloads that are already running in a cluster or project before a PSP is assigned will not be checked to determine if they comply with the PSP. Workloads would need to be cloned or upgraded to see if they pass the PSP.

## Pod Security Policies
|
||||
|
||||
_Pod Security Policies_ (or PSPs) are objects that control security-sensitive aspects of pod specification, e.g. root privileges. If a pod does not meet the conditions specified in the PSP, Kubernetes will not allow it to start, and Rancher will display an error message.
|

[Pod Security Policies (PSPs)](https://kubernetes.io/docs/concepts/security/pod-security-policy/) are objects that control security-sensitive aspects of the pod specification (such as root privileges).
|
||||
|
||||
If a pod doesn't meet the conditions specified in the PSP, Kubernetes won't allow it to start, and Rancher will display the following error message: `Pod <NAME> is forbidden: unable to validate...`.
|
||||
|
||||
|
||||
## How PSPs Work
|
||||
|
||||
You can assign PSPs at the cluster or project level.
|
||||
|
||||
PSPs work through inheritance:
|
||||
|
||||
- By default, PSPs assigned to a cluster are inherited by its projects, as well as any namespaces added to those projects.
|
||||
- **Exception:** Namespaces that are not assigned to projects do not inherit PSPs, regardless of whether the PSP is assigned to a cluster or project. Because these namespaces have no PSPs, workload deployments to these namespaces will fail, which is the default Kubernetes behavior.
|
||||
- You can override the default PSP by assigning a different PSP directly to the project.
|
||||
|
||||
Any workloads that are already running in a cluster or project before a PSP is assigned will not be checked if it complies with the PSP. Workloads would need to be cloned or upgraded to see if they pass the PSP.
|
||||
|
||||
Read more about Pod Security Policies in the [Kubernetes documentation](https://kubernetes.io/docs/concepts/policy/pod-security-policy/).
|
||||
|
||||
## Default PSPs
|
||||
|
||||
Rancher ships with three default Pod Security Policies (PSPs): the `restricted-noroot`, `restricted` and `unrestricted` policies.
|
||||
|
||||
### Restricted-NoRoot
|
||||
|
||||
This policy is based on the Kubernetes [example restricted policy](https://raw.githubusercontent.com/kubernetes/website/master/content/en/examples/policy/restricted-psp.yaml). It significantly restricts what types of pods can be deployed to a cluster or project. This policy:
|
||||
|
||||
- Prevents pods from running as a privileged user and prevents escalation of privileges.
|
||||
- Validates that server-required security mechanisms are in place, such as restricting what volumes can be mounted to only the core volume types and preventing root supplemental groups from being added.
|
||||
|
||||
### Restricted
|
||||
|
||||
This policy is a relaxed version of the `restricted-noroot` policy, with almost all the restrictions in place, except for the fact that it allows running containers as a privileged user.
|
||||
|
||||
### Unrestricted
|
||||
|
||||
This policy is equivalent to running Kubernetes with the PSP controller disabled. It has no restrictions on what pods can be deployed into a cluster or project.
|
||||
|
||||
:::note important
|
||||
|
||||
When disabling PSPs, default PSPs are **not** automatically deleted from your cluster. You must manually delete them if they're no longer needed.
|
||||
|
||||
:::
|
||||
|
||||
## Creating PSPs
|
||||
|
||||
Using Rancher, you can create a Pod Security Policy using our GUI rather than creating a YAML file.
|
||||
|
||||
### Requirements
|
||||
|
||||
Rancher can only assign PSPs for clusters that are [launched using RKE](../launch-kubernetes-with-rancher/launch-kubernetes-with-rancher.md).
|
||||
|
||||
You must enable PSPs at the cluster level before you can assign them to a project. This can be configured by [editing the cluster](../../../reference-guides/cluster-configuration/cluster-configuration.md).
|
||||
|
||||
It is a best practice to set PSP at the cluster level.
|
||||
|
||||
We recommend adding PSPs during cluster and project creation instead of adding it to an existing one.
|
||||
|
||||
### Creating PSPs in the Rancher UI
|
||||
|
||||
1. In the upper left corner, click **☰ > Cluster Management**.
|
||||
1. In the left navigation bar, click **Pod Security Policies**.
|
||||
1. Click **Add Policy**.
|
||||
1. Name the policy.

||||
1. Complete each section of the form. Refer to the [Kubernetes documentation](https://kubernetes.io/docs/concepts/policy/pod-security-policy/) for more information on what each policy does.

||||
1. Click **Create**.

### Removing PodSecurityPolicies from Rancher-Maintained Apps & Marketplace Workloads
|
||||
|
||||
Rancher v2.7.2 offers a new major version of Rancher-maintained Helm charts. v102.x.y allows you to remove PSPs that were installed with previous versions of the chart. This new version replaces non-standard PSPs switches with the standardized `global.cattle.psp.enabled` switch, which is turned off by default.
|
||||
|
||||
You must perform the following steps _while still in Kubernetes v1.24_:
|
||||
1. Configure the PSA controller to suit your needs. You can use one of Rancher's built-in [PSA Configuration Templates](#pod-security-admission-configuration-templates), or create a custom template and apply it to the clusters that you are migrating.

```
|
||||
|
||||
1. Follow the Kubernetes guide on [Mapping PSPs to Pod Security Standards](https://kubernetes.io/docs/reference/access-authn-authz/psp-to-pod-security-standards/) to apply PSSs to your workloads that were relying on PSPs. See [Migrate from PodSecurityPolicy to the Built-In PodSecurity Admission controller](https://kubernetes.io/docs/tasks/configure-pod-container/migrate-from-psp/) for more details.
|
||||
|
||||
1. To remove PSPs from Rancher charts, upgrade the charts to the latest v102.x.y version _before_ you upgrade to Kubernetes v1.25. Make sure that the **Enable PodSecurityPolicies** option is **disabled**. This will remove any PSPs that were installed with previous chart versions.
|
||||
|
||||
:::info important
|
||||
If you want to upgrade your charts to v102.x.y, but don't plan on upgrading your clusters to Kubernetes v1.25 and moving away from PSPs, make sure that you select the option **Enable PodSecurityPolicies** for each chart that you are upgrading.

### Cleaning Up Releases After a Kubernetes v1.25 Upgrade
|
||||
|
||||
If you experience problems while removing PSPs from your charts, or have charts that don't contain a built-in mechanism for removing PSPs, your chart upgrades or deletions might fail with an error message such as the following:
|
||||
```console
|
||||
Error: UPGRADE FAILED: resource mapping not found for name: "<object-name>" namespace: "<object-namespace>" from "": no matches for kind "PodSecurityPolicy" in version "policy/v1beta1"

||||

|
||||
```
|
||||
|
||||
This happens when Helm tries to query the cluster for objects that were stored in a previous release's data blob. To clean up these releases and avoid this error, use the `helm-mapkubeapis` Helm plugin. To learn more about `helm-mapkubeapis`, how it works, and how it can be fine-tuned for your use case, see the [official Helm documentation](https://github.com/helm/helm-mapkubeapis#readme).
