retina-shell

Retina CLI provides a command to launch an interactive shell in a node or pod for adhoc debugging.

• The CLI command kubectl retina shell creates a pod with HostNetwork=true (for node debugging) or an ephemeral container in an existing pod (for pod debugging).
• The container runs an image built from the Dockerfile in this directory. The image is based on Azure Linux and includes commonly-used networking tools.

For testing, you can override the image used by retina shell either with CLI arguments (--retina-shell-image-repo and --retina-shell-image-version) or environment variables (RETINA_SHELL_IMAGE_REPO and RETINA_SHELL_IMAGE_VERSION).

Run kubectl retina shell -h for full documentation and examples.

Currently only Linux is supported; Windows support will be added in the future.
