# This Dockerfile installs all the dependencies necessary to run the unit and
# acceptance tests. This image also contains gcloud so you can run tests
# against a GKE cluster easily.
#
# This image has no automatic entrypoint. It is expected that you'll run
# a script to configure kubectl, potentially install Helm, and run the tests
# manually. This image only has the dependencies pre-installed.
