Seccomp stands for secure computing mode and has been a feature of the Linux kernel since version 2.6.12. It can be used to sandbox the privileges of a process, restricting the calls it is able to make from userspace into the kernel. Kubernetes lets you automatically apply seccomp profiles loaded onto a node to your Pods and containers. Seccomp fields FEATURE STATE: Kubernetes v1.19 [stable] There are four ways to specify a seccomp profile for a pod:

Recommended usage conventions for kubectl. Using kubectl in Reusable Scripts For a stable output in a script: Request one of the machine-oriented output forms, such as -o name, -o json, -o yaml, -o go-template, or -o jsonpath. Fully-qualify the version. For example, jobs.v1.batch/myjob. This will ensure that kubectl does not use its default version that can change over time. Don't rely on context, preferences, or other implicit states. Subresources You can use the --subresource argument for kubectl subcommands such as get, patch, edit, apply and replace to fetch and update subresources for all resources that support them.

FEATURE STATE: Kubernetes v1.33 [beta] Kubernetes 1.35 includes optional declarative validation for APIs. When enabled, the Kubernetes API server can use this mechanism rather than the legacy approach that relies on hand-written Go code (validation.go files) to ensure that requests against the API are valid. Kubernetes developers, and people extending the Kubernetes API, can define validation rules directly alongside the API type definitions (types.go files). Code authors define special comment tags (e.

This page contains an overview of the client libraries for using the Kubernetes API from various programming languages. To write applications using the Kubernetes REST API, you do not need to implement the API calls and request/response types yourself. You can use a client library for the programming language you are using. Client libraries often handle common tasks such as authentication for you. Most client libraries can discover and use the Kubernetes Service Account to authenticate if the API client is running inside the Kubernetes cluster, or can understand the kubeconfig file format to read the credentials and the API Server address.
