# NB: This image does not contain an `ENTRYPOINT` directive. The filesystem
# of this image is used as a layer in other images in CI, and the CLI is
# typically used by operators outside of a cluster.
#
# Running `docker build` for this image will likely fail with an error like:
# "Error response from daemon: No command specified."
