## What is Rancher's deprecation policy?
Starting in Rancher 2.5 we have published our official deprecation policy in the support [terms of service](https://rancher.com/support-maintenance-terms).
### Where can I find out which features have been deprecated in Rancher 2.5?
## Where can I find out which features have been deprecated in Rancher 2.5?
Rancher will publish deprecated features as part of the [release notes](https://github.com/rancher/rancher/releases/tag/v2.5.0) for Rancher found on GitHub.
### What can I expect when a feature is marked for deprecation?
## What can I expect when a feature is marked for deprecation?
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.

When you create a Kubernetes cluster with RKE, RKE creates a `kube_config_cluster.yml` in the local directory that contains credentials to connect to your new cluster with tools like `kubectl` or `helm`.

However, you can still access the cluster to manage your workloads. To access an [RKE cluster,](../how-to-guides/new-user-guides/kubernetes-clusters-in-rancher-setup/launch-kubernetes-with-rancher/launch-kubernetes-with-rancher.md) the cluster must have the [authorized cluster endpoint](../reference-guides/rancher-manager-architecture/communicating-with-downstream-user-clusters.md#4-authorized-cluster-endpoint) enabled, and you must have already downloaded the cluster's kubeconfig file from the Rancher UI. (The authorized cluster endpoint is enabled by default for RKE clusters.) With this endpoint, you can access your cluster with kubectl directly instead of communicating through the Rancher server's [authentication proxy.](../reference-guides/rancher-manager-architecture/communicating-with-downstream-user-clusters.md#1-the-authentication-proxy) For instructions on how to configure kubectl to use the authorized cluster endpoint, refer to the section about directly accessing clusters with [kubectl and the kubeconfig file.](../how-to-guides/advanced-user-guides/manage-clusters/access-clusters/use-kubectl-and-kubeconfig.md#authenticating-directly-with-a-downstream-cluster) These clusters will use a snapshot of the authentication as it was configured when Rancher was removed.

The Layer-4 Load Balancer is created as `type: LoadBalancer`. In Kubernetes, this needs a cloud provider or controller that can satisfy these requests, otherwise these will be in `Pending` state forever.

## How can I automate task X in Rancher?
The UI consists of static files, and works based on responses of the API. That means every action/task that you can execute in the UI, can be automated via the API. There are 2 ways to do this:
* Visit `https://your_rancher_ip/v3` and browse the API options.

## The IP address of a node changed, how can I recover?
A node is required to have a static IP configured (or a reserved IP via DHCP). If the IP of a node has changed, you will have to remove it from the cluster and readd it.

This error occurs when Kubernetes can not find the CRD mentioned. The vast majority of the time these are a result of missing RBAC permissions. Try with an admin user and if this works, add permissions for the resource mentioned by the error (ie. `Get`, `List`, `Patch` as needed).
