Understand how to protect traffic within your cluster using Transport Layer Security (TLS).

When using client certificate authentication, you can generate certificates manually through easyrsa, openssl or cfssl. easyrsa easyrsa can manually generate certificates for your cluster. Download, unpack, and initialize the patched version of easyrsa3. curl -LO https://dl.k8s.io/easy-rsa/easy-rsa.tar.gz tar xzf easy-rsa.tar.gz cd easy-rsa-master/easyrsa3 ./easyrsa init-pki Generate a new certificate authority (CA). --batch sets automatic mode; --req-cn specifies the Common Name (CN) for the CA's new root certificate. ./easyrsa --batch "--req-cn=${MASTER_IP}@`date +%s`" build-ca nopass Generate server certificate and key.

This page shows how to view, work in, and delete namespaces. The page also shows how to use Kubernetes namespaces to subdivide your cluster. Before you begin Have an existing Kubernetes cluster. You have a basic understanding of Kubernetes Pods, Services, and Deployments. Viewing namespaces List the current namespaces in a cluster using: kubectl get namespaces NAME STATUS AGE default Active 11d kube-node-lease Active 11d kube-public Active 11d kube-system Active 11d Kubernetes starts with four initial namespaces:

Perform common configuration tasks for Pods and containers.

Production-Grade Container Orchestration

Creating Secret objects using resource configuration file.

Deploy the web UI (Kubernetes Dashboard) and access it.

This page shows how to configure access to multiple clusters by using configuration files. After your clusters, users, and contexts are defined in one or more configuration files, you can quickly switch between clusters by using the kubectl config use-context command. Note:A file that is used to configure access to a cluster is sometimes called a kubeconfig file. This is a generic way of referring to configuration files. It does not mean that there is a file named kubeconfig.

FEATURE STATE: Kubernetes v1.30 [stable] This page provides an overview of Validating Admission Policy. What is Validating Admission Policy? Validating admission policies offer a declarative, in-process alternative to validating admission webhooks. Validating admission policies use the Common Expression Language (CEL) to declare the validation rules of a policy. Validation admission policies are highly configurable, enabling policy authors to define policies that can be parameterized and scoped to resources as needed by cluster administrators.

FEATURE STATE: Kubernetes v1.18 [stable] Bootstrap tokens are a simple bearer token that is meant to be used when creating new clusters or joining new nodes to an existing cluster. It was built to support kubeadm, but can be used in other contexts for users that wish to start clusters without kubeadm. It is also built to work, via RBAC policy, with the kubelet TLS Bootstrapping system. Bootstrap Tokens Overview Bootstrap Tokens are defined with a specific type (bootstrap.
