The API aggregation layer must be configured on the local Kubernetes cluster for the `v1.ext.cattle.io` `APIService` to work correctly. If the `APIService` does not receive a registration request after the Rancher server starts, the pod will crash with a log entry indicating the error. If your pods are consistently failing to detect registration despite having a correctly configured cluster, you can increase the timeout by setting the `.Values.aggregationRegistrationTimeout` in Helm.
All versions of Kubernetes supported by Rancher with the feature will have the aggregation layer configured by default. However, if you suspect that your cluster configuration is incorrect, refer to the [Kubernetes Aggregation Layer documentation](https://kubernetes.io/docs/tasks/extend-kubernetes/configure-aggregation-layer/) for information on configuring the aggregation layer.

In the release where functionality is marked as "Deprecated", it will still be available and supported allowing upgrades to follow the usual procedure. Once upgraded, users/admins should start planning to move away from the deprecated functionality before upgrading to the release it marked as removed. The recommendation for new deployments is to not use the deprecated feature.

## Identifying the Proper Helm v3 Version
Select any Helm v3 version that is officially compatible with the Kubernetes version range you are using from our [Rancher Support Matrix](https://www.suse.com/suse-rancher/support-matrix/all-supported-versions).
To apply this rule, you may need to reference two external resources:
- **Helm Version Compatibility:** Refer to the [Helm Version Support Policy](https://helm.sh/docs/topics/version_skew/) and select the version matching the rule for your Rancher minor target.
- **Rancher's Kubernetes Support Range:** Use the [Rancher Support Matrix](https://www.suse.com/suse-rancher/support-matrix/all-supported-versions) to identify the Kubernetes versions supported by your target Rancher minor version.
### Example
- **Scenario:** You are targeting Rancher v2.11.4, which supports Kubernetes versions 1.30 through 1.32.
- **Application:** Our rule requires a Helm version that supports this range. You can verify this by checking the Helm version's compatibility with the highest version in the range, Kubernetes v1.32.
- **Result:** You find that both Helm v3.17 and Helm v3.18 support the Kubernetes v1.30-v1.32 range.
- Although both work, we recommend Helm v3.18 because it is the newest Helm minor version overlapping the supported Kubernetes range.
## Additional Notes
- Helm v3.2.x or higher is required to install or upgrade Rancher v2.5.
- Helm v2.16.0 or higher is required for Kubernetes v1.16. For the default Kubernetes version, refer to the [release notes](https://github.com/rancher/rke/releases) for the version of RKE that you are using.
- Helm v2.15.0 should not be used, because of an issue with converting/comparing numbers.
- Helm v2.12.0 should not be used, because of an issue with `cert-manager`.
- Helm v2 support was removed in Rancher v2.9.x.
- When using tools that run Helm commands for you (like Terraform), you must make sure they are configured to use the correct Helm version.

Other services, which are backed up by Rancher Backups, often change and evolve. As this happens, their resources and backup needs may change as well. Some resources may not need to be backed up and some may not be backed up at all. It is important for teams to consider this in their development process and assess whether their related resourceSets are correctly capturing the proper set of resources for their services to be restored correctly.
## Monitoring backups and restores
Rancher offers out-of-the box monitoring features for the Backup Operator. They are disabled by default but can be easily enabled when deploying the operator Helm Chart.
### Metrics
Metrics can be enabled by setting `monitoring.metrics.enabled: true` and `monitoring.serviceMonitor.enabled: true` in the Helm Chart values. When enabled, the Operator exports the following metrics. Note that *rancher-monitoring* needs to be previously installed for the metrics to be properly exported.
| **Metric Name** | **Description** |
|----------------------------------------------------|----------------------------------------------------------------------------------------------------------------------------------------------|
| `rancher_backup_info` | Details on a specific Rancher Backup CR (labels: `name`, `status`, `resourceSetName`, `retentionCount`, `backupType`, `filename`, `storageLocation`, `nextSnapshot`, `lastSnapshot`). Type *GaugeVec*. |
| `rancher_backup_count` | Number of existing Rancher Backup CRs. Type *Gauge*. |
| `rancher_backups_attempted_total` | Total number of Rancher Backups processed by the Operator (labels: `name`). Type *CounterVec*. |
| `rancher_backups_failed_total` | Total number of failed Rancher Backups processed by this operator (labels: `name`). Type *CounterVec*. |
| `rancher_backup_duration_seconds` | Duration of each backup processed by the Operator in seconds (labels: `name`). Type *HistogramVec*, buckets can be customized by the user. |
| `rancher_backup_last_processed_timestamp_seconds` | Unix time of when the last Backup was processed (in seconds) (labels: `name`). Type *GaugeVec*. |
| `rancher_restore_info` | Details on a specific Rancher Restore CR (labels: `name`, `status`, `fileName`, `prune`, `storageLocation`, `restoreTime`). Type *GaugeVec*. |
| `rancher_restore_count` | Number of existing Rancher Restore CRs. Type *Gauge*. |
### Alerting
Only one alert is provided by default, 'BackupFailed', which warns users when a Backup fails to be processed by the Operator. It can be enabled by setting `monitoring.prometheusRules.defaultAlert.enabled: true`.
Users can also deploy their own alerting rules by setting `monitoring.prometheusRules.customRules.enabled: true` and defining them under `monitoring.prometheusRules.customRules.rules`.
### Dashboards
Rancher also provides Grafana dashboards to help monitor the Backup Operator health. These, however, can only be deployed by the *rancher-monitoring* Helm Chart. To do so `rancherBackupMonitoring.dashboards.enabled: true` needs to be set.
## Conclusion
Rancher Backups is a very useful tool, however it is somewhat limited in its scope and intended purposes. In order to avoid possible difficulties, it is important to follow the specific procedures described to ensure the proper operation of the chart.

You can use Rancher to create a cluster hosted in Alibaba Cloud Kubernetes (ACK). Rancher has already implemented and packaged the [cluster driver](../../authentication-permissions-and-global-configuration/about-provisioning-drivers/manage-cluster-drivers.md) for ACK, but by default, this cluster driver is `inactive`. In order to launch ACK clusters, you will need to [enable the ACK cluster driver](../../authentication-permissions-and-global-configuration/about-provisioning-drivers/manage-cluster-drivers.md#activatingdeactivating-cluster-drivers). After enabling the cluster driver, you can start provisioning ACK clusters.
## Prerequisites Outside of Rancher

<link rel="canonical" href="https://ranchermanager.docs.rancher.com/how-to-guides/new-user-guides/launch-kubernetes-with-rancher"/>
</head>
You can have Rancher launch a Kubernetes cluster using any nodes you want. When Rancher deploys Kubernetes onto these nodes, you can choose between [Rancher Kubernetes Engine](https://rancher.com/docs/rke/latest/en/) (RKE) or [RKE2](https://docs.rke2.io) distributions. Rancher can launch Kubernetes on any computers, including:
- Bare-metal servers
- On-premise virtual machines
- Virtual machines hosted by an infrastructure provider
Rancher allows you to launch a Kubernetes cluster on different types of nodes, including bare-metal servers, on-premise virtual machines, and virtual machines from an infrastructure provider. When deploying Kubernetes to these nodes, Rancher gives you the option to use [RKE2](https://docs.rke2.io).
Rancher can install Kubernetes on existing nodes, or it can dynamically provision nodes in an infrastructure provider and install Kubernetes on them.
Rancher can also create pools of nodes. One benefit of installing Kubernetes on node pools hosted by an infrastructure provider is that if a node loses connectivity with the cluster, Rancher can automatically create another node to join the cluster to ensure that the count of the node pool is as expected.
## RKE
### Requirements
If you use RKE to set up a cluster, your nodes must meet the [requirements](../kubernetes-clusters-in-rancher-setup/node-requirements-for-rancher-managed-clusters.md) for nodes in downstream user clusters.
### Launching Kubernetes on New Nodes in an Infrastructure Provider
Using Rancher, you can create pools of nodes based on a [node template](use-new-nodes-in-an-infra-provider/use-new-nodes-in-an-infra-provider.md#node-templates). This node template defines the parameters you want to use to launch nodes in your cloud providers.
One benefit of installing Kubernetes on node pools hosted by an infrastructure provider is that if a node loses connectivity with the cluster, Rancher can automatically create another node to join the cluster to ensure that the count of the node pool is as expected.
For more information, refer to the section on [launching Kubernetes on new nodes.](use-new-nodes-in-an-infra-provider/use-new-nodes-in-an-infra-provider.md)
### Launching Kubernetes on Existing Custom Nodes
In this scenario, you want to install Kubernetes on bare-metal servers, on-prem virtual machines, or virtual machines that already exist in a cloud provider. With this option, you will run a Rancher agent Docker container on the machine.
If you want to reuse a node from a previous custom cluster, [clean the node](../manage-clusters/clean-cluster-nodes.md) before using it in a cluster again. If you reuse a node that hasn't been cleaned, cluster provisioning may fail.
For more information, refer to the section on [custom nodes.](../../../reference-guides/cluster-configuration/rancher-server-configuration/use-existing-nodes/use-existing-nodes.md)
### Programmatically Creating RKE Clusters
The most common way to programmatically deploy RKE clusters through Rancher is by using the Rancher2 Terraform provider. The documentation for creating clusters with Terraform is [here.](https://registry.terraform.io/providers/rancher/rancher2/latest/docs/resources/cluster)
Rancher can also create pools of machines. One benefit of installing Kubernetes on machine pools hosted by an infrastructure provider is that if a node loses connectivity with the cluster, Rancher can automatically create another node to join the cluster to ensure that the count of the machine pool is as expected.

:::caution Known Issue
Service account impersonation (`--as`) used by lower privileged user accounts to remove privileges is not implemented and is a [feature](https://github.com/rancher/rancher/issues/41988) being tracked.
:::
Users technically exist only on the upstream cluster. Rancher creates [RoleBindings and ClusterRoleBindings](https://kubernetes.io/docs/reference/access-authn-authz/rbac/#rolebinding-and-clusterrolebinding) that refer to Rancher users, even though there is [no actual User resource](https://kubernetes.io/docs/reference/access-authn-authz/authentication/#users-in-kubernetes) on the downstream cluster.
When users interact with a downstream cluster through the authentication proxy, there needs to be some entity downstream to serve as the actor for those requests. Rancher creates service accounts to be that entity. Each service account is only granted one permission, which is to **impersonate** the user they belong to. If there was only one service account that could impersonate any user, then it would be possible for a malicious user to corrupt that account and escalate their privileges by impersonating another user. This issue was the basis for a [CVE](https://github.com/rancher/rancher/security/advisories/GHSA-pvxj-25m6-7vqr).

- **RKE2:** Port 6443, used by the Kubernetes API, and port 9345, used for node registration.
These ports have TLS SAN certificates which list nodes' public IP addresses. An attacker could use that information to gain unauthorized access or monitor activity on the cluster. Protecting these ports helps mitigate against nodes' public IP addresses being disclosed to potential attackers.
## Rancher Username Policy
By default, Kubernetes does not provide enforcement mechanisms for baseline username policies. In Rancher, this means that any enforcement of username formats, naming conventions, or baseline policies is expected to be handled by the external identity provider's policies, if such policies are in place.
In Rancher, `admin` is the default username for the Administrator user, as highlighted [here](../../getting-started/installation-and-upgrade/resources/bootstrap-password.md)
Examples of potential baseline policies include:
- Requiring usernames to follow an organizational convention (e.g., `firstname.lastname`)
- Enforcing minimum or maximum length requirements
- Disallowing certain special characters
- Preventing impersonation by disallowing reserved names (e.g., `admin`, `root`)
Without these controls at the identity provider layer, there is a risk of inconsistent or insecure username practices, which can complicate access audits and lead to privilege escalation attempts.
:::note Important
Rancher currently enforces only a [minimum password length](../../how-to-guides/new-user-guides/authentication-permissions-and-global-configuration/authentication-config/manage-users-and-groups.md#minimum-password-length).
:::
**Recommendation:**
We strongly advice that customers:
- Review and configure username baseline policies directly in their external identity providers (e.g., LDAP, Active Directory, SAML, or OIDC).
- Ensure that those policies align with the organization’s security and compliance requirements.
- Regularly audit user accounts to detect naming inconsistencies or policy violations.

## WAF Rules
Rancher is designed to support a wide range of deployment scenarios, including environments where customers may programmatically automate the creation or provisioning of large numbers of clusters. Imposing strict application-level limits within Rancher itself could interfere with legitimate workloads that require dynamic scaling.
For example:
- CI/CD pipelines may create and tear down clusters frequently.
- Self-service portals could provision clusters on-demand for developers.
- Test environments may generate high volumes of API calls.
**Risk:**
Without appropriate rate limiting, adversaries could exploit unauthenticated or authenticated endpoints to:
- Exhaust resources (Denial of Service).
- Inflate storage costs.
- Degrade performance for legitimate users.
**Recommendation:**
The most effective way to mitigate this risk is to implement rate limiting and abuse protection at the infrastructure or Web Application Firewall (WAF) layer. This approach allows thresholds to be tuned for each environment's expected usage and scaling characteristics. Some examples of controls can be:
- Configuring a Web Application Firewall or API Gateway to enforce rate limits on sensitive operations, such as cluster creation and provisioning.
- Defining thresholds based on baseline workload expectations (e.g., max requests per minute per client).
- Monitoring logs and alerting on anomalies to detect potential abuse.
- Apply a resource quota, which is a Rancher feature that limits the resources available to a project or namespace.

Existing projects will not be migrated and only newly created projects will have the new namespace naming convention. If listing projects via `kubectl` the `BackingNampespace` will also be listed as a column. | 24 Apr 2025 | Rancher [v2.11.1](https://github.com/rancher/rancher/releases/tag/v2.11.1), [v2.10.5](https://github.com/rancher/rancher/releases/tag/v2.10.5), and [v2.9.9](https://github.com/rancher/rancher/releases/tag/v2.9.9) |

If a cluster is created based on the mentioned template, and Weave is configured as the CNI, no password will be created for [network encryption](https://github.com/weaveworks/weave/blob/master/site/tasks/manage/security-untrusted-networks.md) in Weave; therefore, network traffic in the cluster will be sent unencrypted. | 24 May 2022 | [Rancher v2.6.5](https://github.com/rancher/rancher/releases/tag/v2.6.5) and [Rancher v2.5.14](https://github.com/rancher/rancher/releases/tag/v2.5.14) |
| [CVE-2021-36784](https://github.com/rancher/rancher/security/advisories/GHSA-jwvr-vv7p-gpwq) | A vulnerability was discovered in Rancher versions from 2.5.0 up to and including 2.5.12 and from 2.6.0 up to and including 2.6.3 which allows users who have create or update permissions on [Global Roles](../../how-to-guides/new-user-guides/authentication-permissions-and-global-configuration/manage-role-based-access-control-rbac/manage-role-based-access-control-rbac.md) to escalate their permissions, or those of another user, to admin-level permissions. Global Roles grant users Rancher-wide permissions, such as the ability to create clusters. In the identified versions of Rancher, when users are given permission to edit or create Global Roles, they are not restricted to only granting permissions which they already posses. This vulnerability affects customers who utilize non-admin users that are able to create or edit Global Roles. The most common use case for this scenario is the `restricted-admin` role. | 14 Apr 2022 | [Rancher v2.6.4](https://github.com/rancher/rancher/releases/tag/v2.6.4) and [Rancher v2.5.13](https://github.com/rancher/rancher/releases/tag/v2.5.13) |
| [CVE-2021-4200](https://github.com/rancher/rancher/security/advisories/GHSA-hx8w-ghh8-r4xf) | This vulnerability only affects customers using the `restricted-admin` role in Rancher. A vulnerability was discovered in Rancher versions from 2.5.0 up to and including 2.5.12 and from 2.6.0 up to and including 2.6.3 where the `global-data` role in `cattle-global-data` namespace grants write access to the Catalogs. Since each user with any level of catalog access was bound to the `global-data` role, this grants write access to templates (`CatalogTemplates`) and template versions (`CatalogTemplateVersions`) for any user with any level of catalog access. New users created in Rancher are by default assigned to the `user` role (standard user), which is not designed to grant write catalog access. This vulnerability effectively elevates the privilege of any user to write access for the catalog template and catalog template version resources. | 14 Apr 2022 | [Rancher v2.6.4](https://github.com/rancher/rancher/releases/tag/v2.6.4) and [Rancher v2.5.13](https://github.com/rancher/rancher/releases/tag/v2.5.13) |
| [GHSA-wm2r-rp98-8pmh](https://github.com/rancher/rancher/security/advisories/GHSA-wm2r-rp98-8pmh) | This vulnerability only affects customers using [Continuous Delivery with Fleet](../../integrations-in-rancher/fleet/fleet.md) for continuous delivery with authenticated Git and/or Helm repositories. An issue was discovered in `go-getter` library in versions prior to [`v1.5.11`](https://github.com/hashicorp/go-getter/releases/tag/v1.5.11) that exposes SSH private keys in base64 format due to a failure in redacting such information from error messages. The vulnerable version of this library is used in Rancher through Fleet in versions of Fleet prior to [`v0.3.9`](https://github.com/rancher/fleet/releases/tag/v0.3.9). This issue affects Rancher versions 2.5.0 up to and including 2.5.12 and from 2.6.0 up to and including 2.6.3. The issue was found and reported by Dagan Henderson from Raft Engineering. | 14 Apr 2022 | [Rancher v2.6.4](https://github.com/rancher/rancher/releases/tag/v2.6.4) and [Rancher v2.5.13](https://github.com/rancher/rancher/releases/tag/v2.5.13) |
| [CVE-2021-36778](https://github.com/rancher/rancher/security/advisories/GHSA-4fc7-hc63-7fjg) | A vulnerability was discovered in Rancher versions from 2.5.0 up to and including 2.5.11 and from 2.6.0 up to and including 2.6.2, where an insufficient check of the same-origin policy when downloading Helm charts from a configured private repository can lead to exposure of the repository credentials to a third-party provider. This issue only happens when the user configures access credentials to a private repository in Rancher inside `Apps & Marketplace > Repositories`. The issue was found and reported by Martin Andreas Ullrich. | 14 Apr 2022 | [Rancher v2.6.3](https://github.com/rancher/rancher/releases/tag/v2.6.3) and [Rancher v2.5.12](https://github.com/rancher/rancher/releases/tag/v2.5.12) |
| [GHSA-hwm2-4ph6-w6m5](https://github.com/rancher/rancher/security/advisories/GHSA-hwm2-4ph6-w6m5) | A vulnerability was discovered in versions of Rancher starting 2.0 up to and including 2.6.3. The `restricted` pod security policy (PSP) provided in Rancher deviated from the upstream `restricted` policy provided in Kubernetes on account of which Rancher's PSP had `runAsUser` set to `runAsAny`, while upstream had `runAsUser` set to `MustRunAsNonRoot`. This allowed containers to run as any user, including a privileged user (`root`), even when Rancher's `restricted` policy was enforced on a project or at the cluster level. | 31 Mar 2022 | [Rancher v2.6.4](https://github.com/rancher/rancher/releases/tag/v2.6.4) |
| [CVE-2021-36775](https://github.com/rancher/rancher/security/advisories/GHSA-28g7-896h-695v) | A vulnerability was discovered in Rancher versions up to and including 2.4.17, 2.5.11 and 2.6.2. After removing a `Project Role` associated with a group from the project, the bindings that granted access to cluster-scoped resources for those subjects were not deleted. This was due to an incomplete authorization logic check. A user who was a member of the affected group with authenticated access to Rancher could exploit this vulnerability to access resources they shouldn't have had access to. The exposure level would depend on the original permission level granted to the affected project role. This vulnerability only affected customers using group based authentication in Rancher. | 31 Mar 2022 | [Rancher v2.6.3](https://github.com/rancher/rancher/releases/tag/v2.6.3), [Rancher v2.5.12](https://github.com/rancher/rancher/releases/tag/v2.5.12) and [Rancher v2.4.18](https://github.com/rancher/rancher/releases/tag/v2.4.18) |
| [CVE-2021-36776](https://github.com/rancher/rancher/security/advisories/GHSA-gvh9-xgrq-r8hw) | A vulnerability was discovered in Rancher versions starting 2.5.0 up to and including 2.5.9, that allowed an authenticated user to impersonate any user on a cluster through an API proxy, without requiring knowledge of the impersonated user's credentials. This was due to the API proxy not dropping the impersonation header before sending the request to the Kubernetes API. A malicious user with authenticated access to Rancher could use this to impersonate another user with administrator access in Rancher, thereby gaining administrator level access to the cluster. | 31 Mar 2022 | [Rancher v2.6.0](https://github.com/rancher/rancher/releases/tag/v2.6.0) and [Rancher v2.5.10](https://github.com/rancher/rancher/releases/tag/v2.5.10) |
| [CVE-2021-25318](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-25318) | A vulnerability was discovered in Rancher versions 2.0 through the aforementioned fixed versions, where users were granted access to resources regardless of the resource's API group. For example, Rancher should have allowed users access to `apps.catalog.cattle.io`, but instead incorrectly gave access to `apps.*`. Resources affected in the **Downstream clusters** and **Rancher management cluster** can be found [here](https://github.com/rancher/rancher/security/advisories/GHSA-f9xf-jq4j-vqw4). There is not a direct mitigation besides upgrading to the patched Rancher versions. | 14 Jul 2021 | [Rancher v2.5.9](https://github.com/rancher/rancher/releases/tag/v2.5.9) and [Rancher v2.4.16](https://github.com/rancher/rancher/releases/tag/v2.4.16) |
| [CVE-2021-31999](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-31999) | A vulnerability was discovered in Rancher 2.0.0 through the aforementioned patched versions, where a malicious Rancher user could craft an API request directed at the proxy for the Kubernetes API of a managed cluster to gain access to information they do not have access to. This is done by passing the "Impersonate-User" or "Impersonate-Group" header in the Connection header, which is then correctly removed by the proxy. At this point, instead of impersonating the user and their permissions, the request will act as if it was from the Rancher management server and incorrectly return the information. The vulnerability is limited to valid Rancher users with some level of permissions on the cluster. There is not a direct mitigation besides upgrading to the patched Rancher versions. | 14 Jul 2021 | [Rancher v2.5.9](https://github.com/rancher/rancher/releases/tag/v2.5.9) and [Rancher v2.4.16](https://github.com/rancher/rancher/releases/tag/v2.4.16) |

Specifically through a proxy designed to communicate with cloud providers. Any Rancher user that was logged-in and aware of a cloud-credential ID that was valid for a given cloud provider, could call that cloud provider's API through the proxy API, and the cloud-credential would be attached. The exploit is limited to valid Rancher users. There is not a direct mitigation outside of upgrading to the patched Rancher versions. | 14 Jul 2021 | [Rancher v2.5.9](https://github.com/rancher/rancher/releases/tag/v2.5.9) and [Rancher v2.4.16](https://github.com/rancher/rancher/releases/tag/v2.4.16) |

If you installed Kubernetes with RKE2/K3s, the Kubeconfig is stored in the `/etc/rancher/rke2/rke2.yaml` or `/etc/rancher/k3s/k3s.yaml` directory depending on your chosen distribution.
kubeconfig 也可以通过 `--kubeconfig` 标签(详情请参见 https://helm.sh/docs/helm/helm/ )来手动指定所需的集群。

</head>
Rancher 可以使用任意节点启动 Kubernetes 集群。在 Rancher 中将 Kubernetes 部署到这些节点上时,你可以选择 [Rancher Kubernetes Engine](https://rancher.com/docs/rke/latest/en/) (RKE) 或 [RKE2](https://docs.rke2.io) 发行版。Rancher 可以在任何计算机上启动 Kubernetes,包括:
Rancher allows you to launch a Kubernetes cluster on different types of nodes, including bare-metal servers, on-premise virtual machines, and virtual machines from an infrastructure provider. When deploying Kubernetes to these nodes, Rancher gives you the option to use [RKE2](https://docs.rke2.io).
- 裸金属服务器
- 本地虚拟机
- 由云厂商托管的虚拟机
Rancher can install Kubernetes on existing nodes, or it can dynamically provision nodes in an infrastructure provider and install Kubernetes on them.
Rancher 可以在现有节点上安装 Kubernetes,也可以在云厂商中动态配置节点并安装 Kubernetes。
Rancher 还可以创建节点池。在托管在云厂商的节点池上安装 Kubernetes 的一个好处是,如果一个节点与集群断开连接,Rancher 可以自动创建另一个节点并将其加入集群,从而确保节点池的数量符合要求。
## RKE
### 要求
如果你使用 RKE 建立集群,节点必须满足下游集群的[节点要求](../kubernetes-clusters-in-rancher-setup/node-requirements-for-rancher-managed-clusters.md)。
### 在云厂商的新节点上启动 Kubernetes
使用 Rancher,你可以基于[节点模板](use-new-nodes-in-an-infra-provider/use-new-nodes-in-an-infra-provider.md#节点模板)创建节点池。此节点模板定义了要用于在云厂商中启动节点的参数。
在托管在云厂商的节点池上安装 Kubernetes 的一个好处是,如果一个节点与集群断开连接,Rancher 可以自动创建另一个节点并将其加入集群,从而确保节点池的数量符合要求。
有关详细信息,请参阅[在新节点上启动 Kubernetes](use-new-nodes-in-an-infra-provider/use-new-nodes-in-an-infra-provider.md)。
### 在现有自定义节点上启动 Kubernetes
在这种情况下,你希望将 Kubernetes 安装到裸机服务器、本地虚拟机或云厂商中已存在的虚拟机上。使用此选项,你将在主机上运行 Rancher Agent Docker 容器。
如果要重复使用之前的自定义集群中的节点,请在复用之前[清理节点](../manage-clusters/clean-cluster-nodes.md)。如果你重复使用尚未清理的节点,则集群配置可能会失败。
有关详细信息,请参阅[自定义节点](../../../reference-guides/cluster-configuration/rancher-server-configuration/use-existing-nodes/use-existing-nodes.md)。
### 以编程方式创建 RKE 集群
通过 Rancher 以编程方式部署 RKE 集群的最常见方法是使用 Rancher 2 Terraform Provider。详情请参见[使用 Terraform 创建集群](https://registry.terraform.io/providers/rancher/rancher2/latest/docs/resources/cluster)。
Rancher can also create pools of machines. One benefit of installing Kubernetes on machine pools hosted by an infrastructure provider is that if a node loses connectivity with the cluster, Rancher can automatically create another node to join the cluster to ensure that the count of the machine pool is as expected.
## RKE2
Rancher 2.6 支持直接使用 Rancher UI 配置 [RKE2](https://docs.rke2.io/) 集群。RKE2,也称为 RKE Government,是一个完全符合标准的 Kubernetes 发行版,它专注于安全性和合规性。在 Rancher 2.6.4 及更早版本中,RKE2 配置还处于技术预览阶段。
Rancher v2.6 introduced provisioning for [RKE2](https://docs.rke2.io/) clusters directly from the Rancher UI. RKE2, also known as RKE Government, is a fully conformant Kubernetes distribution that focuses on security and compliance within the U.S. Federal Government sector. In Rancher v.2.6.4 and earlier, RKE2 provisioning was in tech preview.
在 Rancher 2.6.5 中,RKE2 已经 GA。
Note that in Rancher v2.6.5, RKE2 provisioning became GA.
### 要求
### Requirements
如果你使用 RKE2 建立集群,节点必须满足下游集群的[节点要求](https://docs.rke2.io/install/requirements)。
If you use RKE2 to set up a cluster, your nodes must meet the [requirements](https://docs.rke2.io/install/requirements) for nodes in downstream user clusters.
### 在云厂商的新节点上启动 Kubernetes
### Launching Kubernetes on New Nodes in an Infrastructure Provider
RKE2 基于使用上游[集群 API](https://github.com/kubernetes-sigs/cluster-api) 项目的新配置框架。这个新配置框架支持:
RKE2 provisioning is built on top of a new provisioning framework that leverages the upstream [Cluster API (CAPI)](https://github.com/kubernetes-sigs/cluster-api) project. With this new provisioning framework, you can:
- 将 RKE2 集群配置到 Rancher 具有主机驱动的任何提供商上
- 完全在 Rancher 中配置 RKE2 集群
- 除了 Canal 之外,还可以选择 CNI 选项, Calico、Cilium 和 Multus
- Provision RKE2 clusters onto any provider for which Rancher has a node driver.
- Fully configure RKE2 clusters within Rancher.
- Choose CNI options Calico, Cilium, and Multus in addition to Canal.
RKE2 配置还包括在具有 Windows 节点的集群上安装 RKE2。
When you make changes to your cluster configuration in RKE2, this may result in nodes reprovisioning. This is controlled by CAPI controllers and not by Rancher itself. Note that for etcd nodes, the same behavior does not apply.
RKE2 的 Windows 功能包括:
The following are some specific example configuration changes that may cause the described behavior:
- Windows 支持 vSphere 主机驱动
- 用于 Windows RKE2 自定义集群的 Calico CNI
- Calico 的项目网络隔离 (PNI)
- 由 containerd 提供支持的使用 RKE2 的 Windows 容器
- 通过 Terraform 配置 Windows RKE2 集群
- 直接从 Rancher UI 配置 Windows RKE2 自定义集群
- When editing the cluster and enabling drain before delete, the existing control plane nodes and worker are deleted and new nodes are created.
要使 Windows 支持 RKE2 自定义集群,请选择 Calico 作为 CNI。
RKE2 provisioning also includes installing RKE2 on clusters with Windows nodes.
### 在现有自定义节点上启动 Kubernetes
Windows features for RKE2 include:
RKE2 还支持在预配置的虚拟机或裸机节点上安装自定义集群。
- Windows supports the vSphere node driver
- Calico and Flannel CNI for Windows RKE2 custom clusters
- Project Network Isolation (PNI) for Calico
- Windows Containers with RKE2 powered by containerd
- Provisioning of Windows RKE2 clusters through Terraform
- Provisioning of Windows RKE2 custom clusters directly from the Rancher UI
如果要重复使用之前的自定义集群中的节点,请在复用之前清理节点。如果你重复使用尚未清理的节点,则集群配置可能会失败。
Windows Support for RKE2 Custom Clusters requires choosing Calico as the CNI.
### 以编程方式创建 RKE2 集群
### Launching Kubernetes on Existing Custom Nodes
通过 Rancher 以编程方式部署 RKE2 集群的最常见方法是使用 Rancher 2 Terraform Provider。详情请参见[使用 Terraform 创建集群](https://registry.terraform.io/providers/rancher/rancher2/latest/docs/resources/cluster_v2)。
RKE2 provisioning also allows you to install custom clusters on previously provisioned VMs or bare-metal nodes.
If you want to reuse a node from a previous custom cluster, [clean the node](../manage-clusters/clean-cluster-nodes.md#cleaning-up-nodes) before using it in a cluster again. If you reuse a node that hasn't been cleaned, cluster provisioning may fail.
### Programmatically Creating RKE2 Clusters
The most common way to programmatically deploy RKE2 clusters through Rancher is by using the [Rancher2 Terraform provider](https://registry.terraform.io/providers/rancher/rancher2/latest/docs/resources/cluster_v2).

| [GHSA-wm2r-rp98-8pmh](https://github.com/rancher/rancher/security/advisories/GHSA-wm2r-rp98-8pmh) | 此漏洞仅影响使用经过认证的 Git 和/或 Helm 仓库通过 [Fleet](../../integrations-in-rancher/fleet/fleet.md) 进行持续交付的客户。在 [`v1.5.11`](https://github.com/hashicorp/go-getter/releases/tag/v1.5.11) 之前版本中的 `go-getter` 库中发现了一个问题,错误消息中没有删除 Base64 编码的 SSH 私钥,导致该信息暴露。Rancher 中 [`v0.3.9`](https://github.com/rancher/fleet/releases/tag/v0.3.9) 之前的 Fleet 版本使用了该库的漏洞版本。此问题影响 Rancher 2.5.0 到 2.5.12(包括 2.5.12)以及 2.6.0 到 2.6.3(包括 2.6.3)。该问题由 Raft Engineering 的 Dagan Henderson 发现并报告。 | 2022 年 4 月 14 日 | [Rancher 2.6.4](https://github.com/rancher/rancher/releases/tag/v2.6.4) 和 [Rancher 2.5.13](https://github.com/rancher/rancher/releases/tag/v2.5.13) |
| [CVE-2021-36778](https://github.com/rancher/rancher/security/advisories/GHSA-4fc7-hc63-7fjg) | 在 Rancher 2.5.0 到 2.5.11 和 Rancher 2.6.0 到 2.6.2 中发现了一个漏洞,当从配置的私有仓库下载 Helm Chart 时,对同源策略的检查不足可能导致仓库凭证暴露给第三方提供商。仅当用户在 Rancher 的`应用 & 应用市场 > 仓库`中配置私有仓库的访问凭证时才会出现此问题。该问题由 Martin Andreas Ullrich 发现并报告。 | 2022 年 4 月 14 日 | [Rancher 2.6.3](https://github.com/rancher/rancher/releases/tag/v2.6.3) 和 [Rancher 2.5.12](https://github.com/rancher/rancher/releases/tag/v2.5.12) |
| [GHSA-hwm2-4ph6-w6m5](https://github.com/rancher/rancher/security/advisories/GHSA-hwm2-4ph6-w6m5) | 在 Rancher 2.0 到 2.6.3 中发现了一个漏洞。Rancher 提供的 `restricted` Pod 安全策略(PSP)与 Kubernetes 提供的上游 `restricted` 策略有差别,因此 Rancher 的 PSP 将 `runAsUser` 设置为 `runAsAny`,而上游将 `runAsUser` 设置为 `MustRunAsNonRoot`。因此,即使 Rancher 的 `restricted` 策略是在项目或集群级别上强制执行的,容器也可以以任何用户身份运行,包括特权用户 (`root`)。 | 2022 年 3 月 31 日 | [Rancher 2.6.4](https://github.com/rancher/rancher/releases/tag/v2.6.4) |
| [CVE-2021-36775](https://github.com/rancher/rancher/security/advisories/GHSA-28g7-896h-695v) | 在 Rancher 2.4.17、2.5.11 和 2.6.2 以及更高的版本中发现了一个漏洞。从项目中删除与某个组关联的`项目角色`后,能让这些使用者访问集群级别资源的绑定(Binding)不会被删除。导致问题的原因是不完整的授权逻辑检查。如果用户是受影响组中的成员,且能对 Rancher 进行认证访问,那么用户可以利用此漏洞访问他们不应该能访问的资源。暴露级别取决于受影响项目角色的原始权限级别。此漏洞仅影响在 Rancher 中基于组进行身份验证的客户。 | 2022 年 3 月 31 日 | [Rancher 2.6.3](https://github.com/rancher/rancher/releases/tag/v2.6.3)、[Rancher 2.5.12](https://github.com/rancher/rancher/releases/tag/v2.5.12) 和 [Rancher 2.4.18](https://github.com/rancher/rancher/releases/tag/v2.4.18) |
| [CVE-2021-36776](https://github.com/rancher/rancher/security/advisories/GHSA-gvh9-xgrq-r8hw) | 在 Rancher 2.5.0 到 2.5.9 中发现了一个漏洞,该漏洞允许经过认证用户通过 API 代理模拟集群上的任何用户,而无需知道被模拟用户的凭证。问题的原因是 API 代理在将请求发送到 Kubernetes API 之前未删除模拟标头。能认证访问 Rancher 的恶意用户可以冒充另一个在 Rancher 认证用户,从而对集群进行管理员级别的访问。 | 2022 年 3 月 31 日 | [Rancher 2.6.0](https://github.com/rancher/rancher/releases/tag/v2.6.0) 和 [Rancher 2.5.10](https://github.com/rancher/rancher/releases/tag/v2.5.10) |
| [CVE-2021-25318](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-25318) | Rancher 2.0 的不可编辑版本发现了一个漏洞,在该版本中,无论资源的 API 组如何,用户都可以访问资源。例如,Rancher 应该允许用户访问 `apps.catalog.cattle.io`,但却错误地授予了对 `apps.*` 的访问权限。你可以在[这里](https://github.com/rancher/rancher/security/advisories/GHSA-f9xf-jq4j-vqw4)找到**下游集群**和 **Rancher 管理集群**中受影响的资源。除了升级到打了补丁的 Rancher 版本之外,暂时没有直接的缓解措施。 | 2021 年 7 月 14 日 | [Rancher 2.5.9](https://github.com/rancher/rancher/releases/tag/v2.5.9) 和 [Rancher 2.4.16](https://github.com/rancher/rancher/releases/tag/v2.4.16) |
| [CVE-2021-31999](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2021-31999) | Rancher 2.0.0 的补丁版本发现了一个漏洞,恶意的 Rancher 用户可以针对托管集群的 Kubernetes API 的代理发起一个 API 请求,以获取他们无权访问的信息。这是通过在 Connection 标头中传递 “Impersonate-User” 或 “Impersonate-Group” 标头来实现的,然后代理会删除该标头。此时,请求不会模拟用户及其权限,而是会类似 Rancher management server 的请求,并错误地返回信息。该漏洞仅影响对集群具有一定级别权限的 Rancher 用户。除了升级到打了补丁的 Rancher 版本之外,暂时没有直接的缓解措施。 | 2021 年 7 月 14 日 | [Rancher 2.5.9](https://github.com/rancher/rancher/releases/tag/v2.5.9) 和 [Rancher 2.4.16](https://github.com/rancher/rancher/releases/tag/v2.4.16) |

#### 安装 `helm-mapkubeapis`
1. 在打算使用 `helm-mapkubeapis` 的机器上打开你的终端并安装插件:
```shell
helm plugin install https://github.com/helm/helm-mapkubeapis
```
你将看到类似于以下的输出:
```console
Downloading and installing helm-mapkubeapis v0.4.1 ...
https://github.com/helm/helm-mapkubeapis/releases/download/v0.4.1/helm-mapkubeapis_0.4.1_darwin_amd64.tar.gz
Installed plugin: mapkubeapis
```
:::info 重要提示
确保 `helm-mapkubeapis` 插件至少为 v0.4.1,因为旧版本_不_支持资源删除。
:::
1. 验证插件是否已正确安装:
```shell
helm mapkubeapis --help
```
你将看到类似于以下的输出:
```console
Map release deprecated or removed Kubernetes APIs in-place
Usage:
mapkubeapis [flags] RELEASE
Flags:
--dry-run simulate a command
-h, --help help for mapkubeapis
--kube-context string name of the kubeconfig context to use
--kubeconfig string path to the kubeconfig file
--mapfile string path to the API mapping file
--namespace string namespace scope of the release
```
#### 清理损坏的版本
安装 `helm-mapkubeapis` 插件后,清理升级到 Kubernetes v1.25 后损坏的版本。
1. 打开你的首选终端并通过运行 `kubectl cluster-info` 确保终端已连接到所需集群。
1. 运行 `helm list --all-namespaces` 列出你在集群中安装的所有版本。
1. 通过运行 `helm mapkubeapis --dry-run <release-name> --namespace <release-namespace>` 为要清理的每个版本执行试运行。你可以通过此命令的结果了解要替换或删除哪些资源。
1. 最后,在查看更改后,使用 `helm mapkubeapis <release-name> --namespace <release-namespace>` 执行完整运行。
