earthly-elixir

Attempt at making generic Elixir functions for earthly that utilize caching.

Getting started

Install earthly: https://docs.earthly.dev/install

Usage

VERSION --global-cache 0.7

IMPORT github.com/albert-io/earthly-elixir:main AS elixir

build:
    ARG ELIXIR_VERSION=1.15.4
    ARG OTP_VERSION=26.0.2
    ARG DEBIAN_VERSION=bullseye-20230612
    FROM hexpm/elixir:$ELIXIR_VERSION-erlang-$OTP_VERSION-debian-$DEBIAN_VERSION
    RUN apt-get update && apt-get install -y --no-install-recommends \
    git \
    ca-certificates \
    build-essential \
    && apt-get clean && rm -f /var/lib/apt/lists/*_*

    WORKDIR /app

    # Initialize environment variables
    DO elixir+INIT
    # Install rebar and hex
    DO elixir+MIX --command="do local.rebar --force, local.hex --force"

    # Fetch dependencies
    COPY mix.exs mix.lock ./
    DO elixir+MIX --command="deps.get"

    # Compile dependencies
    COPY --if-exists --dir config ./
    DO elixir+MIX --command="deps.compile"

    # Compile application
    COPY --dir lib ./
    DO elixir+MIX --command="clean"
    DO elixir+MIX --command="compile"

test:
    FROM +build
    # Run tests
    DO elixir+MIX --command="test"

    # Run dialyzer
    COPY --if-exists .dialyzer_ignore.exs ./
    DO elixir+MIX --command="dialyzer"

# optionally provide a unique cache id to prevent overriding the global deps and _build cache
# e.g. useful for prs where you don't want to override trunk deps from a branch
pull-request:
    FROM +build
    # Run tests
    DO elixir+MIX --command="test" --cache_id="some-branch-name"

    # Run dialyzer
    COPY --if-exists .dialyzer_ignore.exs ./
    DO elixir+MIX --command="dialyzer" --cache_id="some-branch-name"
