Kubernetes

Kubernetes enables deployment, scaling, and management of containerized applications. IntelliJ IDEA provides support for Kubernetes resource configuration files via the Kubernetes plugin.

The Kubernetes plugin supports Kubernetes API starting from version 1.5. It provides rich support for resource configuration files in YAML, and only basic support for the JSON format.

Resource configuration files

IntelliJ IDEA recognizes Kubernetes resource configuration files using the following mandatory fields:

apiVersion: identifies the versioned schema of the object representation
kind: identifies the object kind (for example, Service, Pod, Deployment, etc.)

If both of the previous fields are present in a YAML or JSON file, IntelliJ IDEA will mark the file with the corresponding Kubernetes icon and enable all available features:

For YAML files, you can also use predefined Live Templates to create the necessary type of configuration:

To see available Live Templates and create new ones, open the Settings/Preferences dialog (Ctrl+Alt+S), click Editor, then click Live Templates, and expand the Kubernetes group in the list.
