Rails can connect to PostgreSQL with GitHub Actions


I have been battling GitHub actions for a while now. I had to switch to GitHub Action after using Travis for a while and cannot set it up to run tests for Rails application. The problem is that no database is started for Rails to connect to and create the database from migrations.

This is my workflow .yml file:

name: Ruby on Rails CI

on:
  push:
    branches: [ master, develop ]
  pull_request:
    branches: [ master, develop ]

jobs:
  test:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        ruby-version: ['2.6', '2.7', '3.0']

services:
  postgres:
    env:
      POSTGRES_DB: postgres        
      POSTGRES_PASSWORD: postgres
      POSTGRES_USER: postgres
    image: postgres:13
    ports:
    - 5432:5432
    options: --health-cmd pg_isready --health-interval 10s --health-timeout 5s --health-retries 5
    
steps:
- uses: actions/checkout@v2

- name: Set up Ruby
  uses: ruby/setup-ruby@v1
  with:
    ruby-version: 2.7.3
    bundler-cache: true # runs 'bundle install' and caches installed gems automatically

- name: Install dependencies
  run: |
    yarn install
    
- name: Build and Test
  run: |
    sudo apt-get -yqq install libpq-dev
    bundle exec rake db:migrate
    bundle exec rake test

The error I am getting from the Actions tab:

I have looked at multiple videos and Stack Overflow discussions regarding this issue, and nothing worked so far. Any help is appreciated.


Solution

  • Try to pass correct test db config ENV. Check and set your variables in database.yml for test db.

    test:
      <<: *default
      database: <%= ENV.fetch('PG_DATABASE', 'postgres') %> 
      host:     <%= ENV.fetch('PG_HOST',  'localhost') %>
      username: <%= ENV.fetch('PG_USER', nil) %>
      password: <%= ENV.fetch('PG_PASSWORD', nil) %>
      port:     <%= ENV.fetch('PG_PORT', 5432) %>
    

    Or add test db config ENV to your workflow.yml:

    - name: Build and Test
      env:
        PG_DATABASE: postgres
        PG_HOST: localhost
        PG_PORT: 5432
        PG_USER: postgres
        PG_PASSWORD: postgres
        RAILS_ENV: test
      run: |
        sudo apt-get -yqq install libpq-dev
        bundle exec rake db:migrate
        bundle exec rake test
    

    Check working example.
