You can use the Kubernetes command line tool kubectl to interact with the API Server. Using kubectl is straightforward if you are familiar with the Docker command line tool. However, there are a few differences between the Docker commands and the kubectl commands. The following sections show a Docker sub-command and describe the equivalent kubectl command. docker run To run an nginx Deployment and expose the Deployment, see kubectl create deployment.

There are two official Kubernetes blogs, and the CNCF has its own blog where you can cover Kubernetes too. For the main Kubernetes blog, we (the Kubernetes project) like to publish articles with different perspectives and special focuses, that have a link to Kubernetes. With only a few special case exceptions, we only publish content that hasn't been submitted or published anywhere else. Writing for the Kubernetes blog(s) As an author, you have three different routes towards publication.

Synopsis Show the status of the rollout. By default 'rollout status' will watch the status of the latest rollout until it's done. If you don't want to wait for the rollout to finish then you can use --watch=false. Note that if a new rollout starts in-between, then 'rollout status' will continue watching the latest revision. If you want to pin to a specific revision and abort if it is rolled over by another revision, use --revision=N where N is the revision you need to watch for.

Synopsis Update environment variables on a pod template. List environment variable definitions in one or more pods, pod templates. Add, update, or remove container environment variable definitions in one or more pod templates (within replication controllers or deployment configurations). View or modify the environment variable definitions on all containers in the specified pods or pod templates, or just those that match a wildcard. If "--env -" is passed, environment variables can be read from STDIN using the standard env syntax.

FieldDescription uid [Required] k8s.io/apimachinery/pkg/types.UID UID is an identifier for the individual request/response. It allows us to distinguish instances of requests which are otherwise identical (parallel requests, requests when earlier requests did not modify etc) The UID is meant to track the round trip (request/response) between the KAS and the WebHook, not the user request.

This page contains an overview of the various feature gates an administrator can specify on different Kubernetes components. See feature stages for an explanation of the stages for a feature. Overview Feature gates are a set of key=value pairs that describe Kubernetes features. You can turn these features on or off using the --feature-gates command line flag on each Kubernetes component. Each Kubernetes component lets you enable or disable a set of feature gates that are relevant to that component.
