Alternative Dockerfiles

There are many different ways to build docker containers with elixir apps. Here is the community-driven list of alternative dockerfile pairs that are compatible with mix_docker two-phased flow. In order to use them simply copy the content into Dockerfile.build and Dockerfile.release files in your project root directory.

Minimal images from @aeons

# Dockerfile.build
FROM aeons/elixir-gcc:1.4.1

ENV MIX_ENV=prod

WORKDIR /opt/app

COPY mix.exs mix.lock ./

RUN mix do deps.get, deps.compile

COPY . .

RUN mix release --env=prod --verbose

# Dockerfile.release
FROM alpine:3.5

RUN apk --no-cache add ncurses-libs

WORKDIR /opt/app/

EXPOSE 4000
ENV PORT=4000 MIX_ENV=prod REPLACE_OS_VARS=true

ADD ${APP}.tar.gz ./

RUN adduser -S default
RUN chown -R default .
USER default

ENTRYPOINT ["/opt/app/bin/${APP}"]
