Production-Grade Container Orchestration

As the Kubernetes API evolves, APIs are periodically reorganized or upgraded. When APIs evolve, the old API is deprecated and eventually removed. This page contains information you need to know when migrating from deprecated API versions to newer and more stable API versions. Removed APIs by release v1.32 The v1.32 release will stop serving the following deprecated API versions: Flow control resources The flowcontrol.apiserver.k8s.io/v1beta3 API version of FlowSchema and PriorityLevelConfiguration will no longer be served in v1.

This page provides a real world example of how to configure Redis using a ConfigMap and builds upon the Configure a Pod to Use a ConfigMap task. Objectives Create a ConfigMap with Redis configuration values Create a Redis Pod that mounts and uses the created ConfigMap Verify that the configuration was correctly applied. Before you begin You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster.

Production-Grade Container Orchestration

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.

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 v1.32 [beta] (enabled by default: true) When the AuthorizeNodeWithSelectors feature is enabled (along with the pre-requisite AuthorizeWithSelectors feature), kubelets are only allowed to read their own Node objects, and are only allowed to read pods bound to their node.
