Production-Grade Container Orchestration

Anyone can review a documentation pull request. Visit the pull requests section in the Kubernetes website repository to see open pull requests. Reviewing documentation pull requests is a great way to introduce yourself to the Kubernetes community. It helps you learn the code base and build trust with other contributors. Before reviewing, it's a good idea to: Read the content guide and style guide so you can leave informed comments.

High-level indicators for measuring the reliability and performance of Kubernetes components.

Production-Grade Container Orchestration

Synopsis Update the service account of pod template resources. Possible resources (case insensitive) can be: replicationcontroller (rc), deployment (deploy), daemonset (ds), job, replicaset (rs), statefulset kubectl set serviceaccount (-f FILENAME | TYPE NAME) SERVICE_ACCOUNT Examples # Set deployment nginx-deployment's service account to serviceaccount1 kubectl set serviceaccount deployment nginx-deployment serviceaccount1 # Print the result (in YAML format) of updated nginx deployment with the service account from local file, without hitting the API server kubectl set sa -f nginx-deployment.

Objectives Learn about Kubernetes Pods. Learn about Kubernetes Nodes. Troubleshoot deployed applications. Kubernetes Pods A Pod is a group of one or more application containers (such as Docker) and includes shared storage (volumes), IP address and information about how to run them. When you created a Deployment in Module 2, Kubernetes created a Pod to host your application instance. A Pod is a Kubernetes abstraction that represents a group of one or more application containers (such as Docker), and some shared resources for those containers.

This page demonstrates how can you run Pods on only some Nodes as part of a DaemonSet 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:

Node authorization is a special-purpose authorization mode that specifically authorizes API requests made by kubelets. Overview The Node authorizer allows a kubelet to perform API operations. This includes: Read operations: services endpoints nodes pods secrets, configmaps, persistent volume claims and persistent volumes related to pods bound to the kubelet's node FEATURE STATE: Kubernetes v1.34 [stable](enabled by default) Kubelets are limited to reading their own Node objects, and only reading pods bound to their node.

This page describes Kubernetes security and disclosure information. Security Announcements Join the kubernetes-security-announce group for emails about security and major API announcements. Report a Vulnerability We're extremely grateful for security researchers and users that report vulnerabilities to the Kubernetes Open Source Community. All reports are thoroughly investigated by a set of community volunteers. To make a report, submit your vulnerability to the Kubernetes bug bounty program. This allows triage and handling of the vulnerability with standardized response times.

FEATURE STATE: Kubernetes v1.27 [beta] This is a community maintained list of official CVEs announced by the Kubernetes Security Response Committee. See Kubernetes Security and Disclosure Information for more details. The Kubernetes project publishes a programmatically accessible feed of published security issues in JSON feed and RSS feed formats. You can access it by executing the following commands: JSON feed RSS feed Link to JSON format curl -Lv https://k8s.io/docs/reference/issues-security/official-cve-feed/index.json Link to RSS format
