Automatic merge from submit-queue kubectl binary plugins **What this PR does / why we need it**: Introduces the ability to extend `kubectl` by adding third-party plugins that will be exposed through `kubectl`. Plugins are executable commands written in any language. To be included as a plugin, a binary or script file has to 1. be located under one of the supported plugin path locations: 1.1 `~/.kubectl/plugins` dir 1.2. one or more directory set in the `KUBECTL_PLUGINS_PATH` env var 1.3. the `kubectl/plugins` dir under one or more directory set in the `XDG_DATA_DIRS` env var, which defaults to `/usr/local/share:/usr/share` 2. in any of the plugin path above, have a subfolder with the plugin file(s) 3. in the subfolder, contain at least a `plugin.yaml` file that describes the plugin Example: ``` $ cat ~/.kube/plugins/myplugin/plugin.yaml name: "myplugin" shortDesc: "My plugin's short description" command: "echo Hello plugins!" $ kubectl myplugin Hello plugins! ``` ~~In case the plugin declares `tunnel: true`, the plugin engine will pass the `KUBECTL_PLUGIN_API_HOST` env var when calling the plugin binary. Plugins can then access the Kube REST API in "http://$KUBECTL_PLUGIN_API_HOST/api" using the same context currently in use by `kubectl`.~~ Test plugins are provided in `pkg/kubectl/plugins/examples`. Just copy (or symlink) the files to `~/.kube/plugins` to test. **Which issue this PR fixes**: Related to the discussions in the proposal document: https://github.com/kubernetes/kubernetes/pull/30086 and https://github.com/kubernetes/community/pull/122. **Release note**: ```release-note Introduces the ability to extend kubectl by adding third-party plugins. Developer preview, please refer to the documentation for instructions about how to use it. ``` |
