⁠Elixir Rust Docker Image

This repo hosts the Dockerfile to produce an image that is based on Alpine, includes Elixir and Rust (with Cargo).

It is used in a CI pipeline to run code standard right away, with no before_script requirements:
mix credo --strict

to run tests:
mix coveralls

And also to build a production ready Elixir release.

Adding Rust to this image allows to compile Rust Nifs based on Rustler.

If a release relies on a Rust NIFs, then your release env. should contain libgcc. For instance here is a working example:

FROM alpine:3.13 AS app
RUN apk add --no-cache openssl ncurses-libs libgcc

WORKDIR /app

RUN chown nobody:nobody /app

USER nobody:nobody

COPY --from=build --chown=nobody:nobody /app/_build/prod/rel ./

ENV HOME=/app

COPY entrypoint.sh .

# Run the Phoenix app
CMD ["./entrypoint.sh"]
