setup-elixir

This action sets up an Elixir environment for use in a GitHub Actions workflow by:

Installing OTP
Installing Elixir

Note Currently, this action currently only supports Actions' ubuntu- runtimes.

Usage

See action.yml.

Note The OTP release version specification is relatively complex. For best results, we recommend specifying exact OTP and Elixir versions. However, values like 22.x are also accepted, and we attempt to resolve them according to semantic versioning rules.

Basic example

on: push

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: actions/setup-elixir@v1.2.0
        with:
          otp-version: 22.2
          elixir-version: 1.9.4
      - run: mix deps.get
      - run: mix test

Matrix example

on: push

jobs:
  test:
    runs-on: ubuntu-latest
    name: OTP ${{matrix.otp}} / Elixir ${{matrix.elixir}}
    strategy:
      matrix:
        otp: [20.3, 21.3, 22.2]
        elixir: [1.8.2, 1.9.4]
    steps:
      - uses: actions/checkout@v2
      - uses: actions/setup-elixir@v1.2.0
        with:
          otp-version: ${{matrix.otp}}
          elixir-version: ${{matrix.elixir}}
      - run: mix deps.get
      - run: mix test

Phoenix example

on: push

jobs:
  test:
    runs-on: ubuntu-latest

    services:
      db:
        image: postgres:11
        ports: ['5432:5432']
        options: >-
          --health-cmd pg_isready
          --health-interval 10s
          --health-timeout 5s
          --health-retries 5

    steps:
      - uses: actions/checkout@v2
      - uses: actions/setup-elixir@v1.2.0
        with:
          otp-version: 22.2
          elixir-version: 1.9.4
