This page provides an overview of best practices when it comes to enforcing Pod Security Standards. Using the built-in Pod Security Admission Controller FEATURE STATE: Kubernetes v1.25 [stable] The Pod Security Admission Controller intends to replace the deprecated PodSecurityPolicies. Configure all cluster namespaces Namespaces that lack any configuration at all should be considered significant gaps in your cluster security model. We recommend taking the time to analyze the types of workloads occurring in each namespace, and by referencing the Pod Security Standards, decide on an appropriate level for each of them.

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

A time-to-live mechanism to clean up old Jobs that have finished execution.

Principles and practices for good Secret management for cluster administrators and application developers.

This page provides an storage overview specific to the Windows operating system. Persistent storage Windows has a layered filesystem driver to mount container layers and create a copy filesystem based on NTFS. All file paths in the container are resolved only within the context of that container. With Docker, volume mounts can only target a directory in the container, and not an individual file. This limitation does not apply to containerd.

Concepts for keeping your cloud-native workload secure.

The dockershim component of Kubernetes allows the use of Docker as a Kubernetes's container runtime. Kubernetes' built-in dockershim component was removed in release v1.24. This page explains how your cluster could be using Docker as a container runtime, provides details on the role that dockershim plays when in use, and shows steps you can take to check whether any workloads could be affected by dockershim removal. Finding if your app has a dependencies on Docker If you are using Docker for building your application containers, you can still run these containers on any container runtime.

Production-Grade Container Orchestration

This page describes the CoreDNS upgrade process and how to install CoreDNS instead of kube-dns. 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:

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:
