-# Test a Phoenix application with GitLab CI/CD

+redirect_to: '../../ci/examples/test_phoenix_app_with_gitlab_ci_cd/index.md'

-This example demonstrates the integration of Gitlab CI with Phoenix, Elixir and
-Postgres.
-
-## Add `.gitlab-ci.yml` to project
-
-The following `.gitlab-ci.yml` should be added in the root of your
-repository to trigger CI:
-
-```yaml
-image: elixir:1.3
-
-services:
-  - postgres:9.6
-
-variables:
-  MIX_ENV: "test"
-
-before_script:
-  # Setup phoenix dependencies
-  - apt-get update
-  - apt-get install -y postgresql-client
-  - mix local.hex --force
-  - mix deps.get --only test
-  - mix ecto.reset
-
-test:
-  script:
-    - mix test
-```
-
-The variables will set the Mix environment to "test". The
-`before_script` will install `psql`, some Phoenix dependencies, and will also
-run your migrations.
-
-Finally, the test `script` will run your tests.
-
-## Update the Config Settings
-
-In `config/test.exs`, update the database hostname:
-
-```elixir
-config :my_app, MyApp.Repo,
-  hostname: if(System.get_env("CI"), do: "postgres", else: "localhost"),
-```
-
-## Add the Migrations Folder
-
-If you do not have any migrations yet, you will need to create an empty
-`.gitkeep` file in `priv/repo/migrations`.
