Debian Docker containers for Elixir

A single CI pipeline to build Erlang / Elixir / Phoenix / Docker in Docker / wkhtmltopdf Docker containers.

Usage

All relevant information is kept in a single file: bin/env-vars.

Following ENV variables are available:

export REFRESHED_AT="2021-07-19"
export DOCKERHUB_USER="quantor"

export DEBIAN_VERSION="11"
export ERLANG_VERSION="24.2.2" # unused currently
export ELIXIR_VERSION="1.13.3-slim" # using official elixir base image

$ bin/render-dockerfiles
$ bin/build-container-for [erlang|elixir|phoenix|docker|wkhtmltopdf]

Opt-in for container building

To prevent waiting for all containers on all commits, following magic strings are used in commit messages:

• [skip ci]
• [with-erlang] - include the Erlang container
• [with-elixir] - include the Elixir container
• [with-phoenix] - include the Phoenix container

To trigger building all 3 containers, use [with-erlang, with-elixir, with-phoenix].

Secrets

Github Actions depend on following secrets being available:
