This page shows how to manually rotate the certificate authority (CA) certificates. Before you begin You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. It is recommended to run this tutorial on a cluster with at least two nodes that are not acting as control plane hosts. If you do not already have a cluster, you can create one by using minikube or you can use one of these Kubernetes playgrounds:

Synopsis Print the supported API resources on the server. kubectl api-resources [flags] Examples # Print the supported API resources kubectl api-resources # Print the supported API resources with more information kubectl api-resources -o wide # Print the supported API resources sorted by a column kubectl api-resources --sort-by=name # Print the supported namespaced resources kubectl api-resources --namespaced=true # Print the supported non-namespaced resources kubectl api-resources --namespaced=false # Print the supported API resources with a specific APIGroup kubectl api-resources --api-group=rbac.

Synopsis Display one or many contexts from the kubeconfig file. kubectl config get-contexts [(-o|--output=)name)] Examples # List all the contexts in your kubeconfig file kubectl config get-contexts # Describe one context in your kubeconfig file kubectl config get-contexts my-context Options -h, --help help for get-contexts --no-headers When using the default or custom-column output format, don't print headers (default print headers). -o, --output string Output format. One of: (name). --as string Username to impersonate for the operation.

Synopsis Edit the latest last-applied-configuration annotations of resources from the default editor. The edit-last-applied command allows you to directly edit any API resource you can retrieve via the command-line tools. It will open the editor defined by your KUBE_EDITOR, or EDITOR environment variables, or fall back to 'vi' for Linux or 'notepad' for Windows. You can edit multiple objects, although changes are applied one at a time. The command accepts file names as well as command-line arguments, although the files you point to must be previously saved versions of resources.

Create a production-quality Kubernetes cluster

You've deployed your application and exposed it via a Service. Now what? Kubernetes provides a number of tools to help you manage your application deployment, including scaling and updating. Organizing resource configurations Many applications require multiple resources to be created, such as a Deployment along with a Service. Management of multiple resources can be simplified by grouping them together in the same file (separated by --- in YAML). For example:

This page describes the lifecycle of a Pod. Pods follow a defined lifecycle, starting in the Pending phase, moving through Running if at least one of its primary containers starts OK, and then through either the Succeeded or Failed phases depending on whether any container in the Pod terminated in failure. Whilst a Pod is running, the kubelet is able to restart containers to handle some kind of faults. Within a Pod, Kubernetes tracks different container states and determines what action to take to make the Pod healthy again.

Gateway API is a family of API kinds that provide dynamic infrastructure provisioning and advanced traffic routing.

A DaemonSet defines Pods that provide node-local facilities. These might be fundamental to the operation of your cluster, such as a networking helper tool, or be part of an add-on.
