# Install dependencies
#
# Since many Python distributions require a compile for their native dependencies
# we install a compiler and any required development libraries before the installation
# and then *remove* the the compiler when we are done.
#
# We can control dependency freezing by managing the contents of `requirements.txt`.
#
# We can speed up the installation a little bit by breaking out the common
# pip dependencies into their own layer, but avoid this optimization for
# now to improve clarity.
#
# We also install the web application server (which should not be one of our
# explicit dependencies).
#
# Many services will need to modify this step for Python libraries with other
# native dependencies.


# Work in /src
#
# We'll copy local source code here for development.

# UTF-8 everywhere.

# Install top-level files

# These are enough to install dependencies and have a stable base layer
# when source code changes.

# Setup invocation

# We expose the application on the standard HTTP port and use an entrypoint
# to customize the `dev` and `test` targets.

# Install source
#
# We should not need to reinstall dependencies here, but we do need to import
# the distribution properly. We also save build arguments to the image using
# microcosm-compatible environment variables.
