Hi @thornomad ,

In the last step, you can access the service container using localhost and the mapped port directly.

POSTGRES_PORT: 5432

Please refer to the doc here for more details.

If it doesn’t work, please kindly share your repo/sample repo for further investigation.

Thanks.

Hello @weide-zhou - thanks for taking time to help me.  I have another repo I had used for a different test (basic rails app that uses postgres with no real configuration).  I added the github action to that app in its own branch to demonstrate the failure I am having.  You can see the action setting at:

https://github.com/thornomad/issue-38279-rails-6/blob/add-github-action/.github/workflows/ruby.yml

I am taking a guess at the config/database.yml setup.  I added the password, username, and port evn variables there.

https://github.com/thornomad/issue-38279-rails-6/blob/add-github-action/config/database.yml#L58-L63

Finally, here is the output from the action.  Am having the same issue as with the other application.

Thanks again.  I feel like all my searching online and trying different examples floating around and I am getting stuck.  Must be something fundamental that I am missing!

Hi - thanks for working with me on this.  It looks like the issue in the end was not defining host: localhost in the database.yml file.

For anyone else who stubmles across this; here is what ended up working for me on a new Rails 6 setup using postgres.  This let’s both the local machine testing environment and github actions do its thing! Thanks again!

env:
  POSTGRES_PASSWORD: postgres
  POSTGRES_USER: postgres
  POSTGRES_HOST: localhost
  RAILS_ENV: test
name: Ruby
on: [push]
jobs:

build:

runs-on: ubuntu-latest

services:

postgres:

image: postgres:latest

ports:

- 5432:5432

env:

POSTGRES_USER: postgres

POSTGRES_PASSWORD: postgres

options: >-

--health-cmd pg_isready

--health-interval 10s

--health-timeout 5s

--health-retries 5
steps:
  - uses: actions/checkout@v2

  - name: Set up Ruby version (using project .ruby-version)
    uses: eregon/use-ruby-action@master

  - name: Install dependent libraries
    run: sudo apt-get install libpq-dev

  - name: Bundle install
    run: |
      gem install bundler
      bundle install --jobs 4 --retry 3

  - name: Setup the postgres database
    run: bundle exec rake db:setup

  - name: Run RSpec tests
    run: bundle exec rspec

 And then the relevant section from database.yml:

test:
  <<: *default
  database: my_app_test
  host: <%= ENV["POSTGRES_HOST"] %>
  username: <%= ENV["POSTGRES_USER"] %>
  password: <%= ENV["POSTGRES_PASSWORD"] %>

Thanks again!
