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.

The Common Expression Language (CEL) is used in the Kubernetes API to declare validation rules, policy rules, and other constraints or conditions. CEL expressions are evaluated directly in the API server, making CEL a convenient alternative to out-of-process mechanisms, such as webhooks, for many extensibility use cases. Your CEL expressions continue to execute so long as the control plane's API server component remains available. Language overview The CEL language has a straightforward syntax that is similar to the expressions in C, C++, Java, JavaScript and Go.

Adding entries to a Pod's /etc/hosts file provides Pod-level override of hostname resolution when DNS and other options are not applicable. You can add these custom entries with the HostAliases field in PodSpec. The Kubernetes project recommends modifying DNS configuration using the hostAliases field (part of the .spec for a Pod), and not by using an init container or other means to edit /etc/hosts directly. Change made in other ways may be overwritten by the kubelet during Pod creation or restart.
