Dockerfile

# We are interested in the binaries compiled on that container:
FROM ghcr.io/etalab/transport-tools:v1.0.7 AS transport-tools

# We leverage the base images published by hexpm at:
#
# https://hub.docker.com/r/hexpm/elixir
#
# Which are built via:
#
# https://github.com/hexpm/bob#docker-images
#
# They provide the ability to decouple Elixir version
# and OTP version, which is a nice feature for
# incremental/decoupled upgrades.
#
# These base images package Elixir and OTP releases found at:
# - https://github.com/elixir-lang/elixir/releases
# - https://github.com/erlang/otp/releases
#
#
# So again, to upgrade this, check out : 
#
# https://hub.docker.com/r/hexpm/elixir
