Dockerfile

# Dockerfile
# * builder steps:
#  - create environment and build package
#  - save environment for runner
# * runner steps:
#  - recreate the same environment and install built package
#  - optionally execute provided console_script in ENTRYPOINT
#
# Alternatively, remove builder steps, take `environment.docker.yml` from your repo
# and `pip install calculoastronomico` using an artifact store. Faster and more robust.
