# WARNING: Stackdriver Debugger is not regularly tested on the Alpine Linux
# platform and support will be on a best effort basis.
# Sample Alpine Linux image including Python and the Stackdriver Debugger agent.
# To build:
#   docker build . # Python 2.7
#   docker build --build-arg PYTHON_VERSION=3 . # Python 3.6
# The final image size should be around 50-60 MiB.

# Stage 1: Build the agent.
