# Start with a docker-layer that contains build dependencies, to maximize the reuse of these dependencies by docker's cache mechanism.
# Only updates to the files stack.yaml package.yaml will rebuild this layer; all other changes use the cache.
# Expect stack to give warnings in this step, which you can ignore.
