## Using PostgreSQL # Using PostgreSQL
It's possible to use PostgreSQL database test your apps during builds. As many applications depend on PostgreSQL as their database, you will
eventually need it in order for your tests to run. Below you are guided how to
do this with the Docker and Shell executors of GitLab Runner.
### Use PostgreSQL with Docker executor ## Use PostgreSQL with the Docker executor
If you are using our Docker integration you basically have everything already. If you are using GitLab's Runner with the Docker executor you basically have
everything set up already.
1. Add this to your `.gitlab-ci.yml`: First, in your `.gitlab-ci.yml` add:
services: ```yaml
- postgres services:
- postgres
variables: variables:
# Configure postgres service (https://hub.docker.com/_/postgres/) POSTGRES_DB: nice_marmot
POSTGRES_DB: hello_world_test POSTGRES_USER: gitlab_runner
POSTGRES_USER: postgres POSTGRES_PASSWORD: ""
POSTGRES_PASSWORD: "" ```
2. Configure your application to use the database: And then configure your application to use PostgreSQL, for example:
Host: postgres ```yaml
User: postgres Host: localhost
Password: postgres User: gitlab_runner
Database: hello_world_test Password:
Database: nice_marmot
```
3. You can also use any other available on [DockerHub](https://hub.docker.com/_/postgres/). For example: `postgres:9.3`. You can also use any other docker image available on [Docker Hub][hub-pg].
For example, to use PostgreSQL 9.3 the service becomes `postgres:9.3`.
Example: https://gitlab.com/gitlab-examples/postgres/blob/master/.gitlab-ci.yml The `postgres` image can accept some environment variables. For more details
check the documentation on [Docker Hub][hub-pg].
### Use PostgreSQL with Shell executor ## Use PostgreSQL with the Shell executor
It's possible to use PostgreSQL on manually configured servers that are using GitLab Runner with Shell executor. You can also use PostgreSQL on manually configured servers that are using
GitLab Runner with the Shell executor.
1. First install the PostgreSQL server: First install the PostgreSQL server:
sudo apt-get install -y postgresql postgresql-client libpq-dev ```bash
sudo apt-get install -y postgresql postgresql-client libpq-dev
```
2. Create an user: Then create a user:
# Install the database packages ```bash
sudo apt-get install -y postgresql postgresql-client libpq-dev # Login to PostgreSQL
sudo -u postgres psql -d template1
# Login to PostgreSQL # Create a user for GitLab Runner that can create databases
sudo -u postgres psql -d template1 # Do not type the 'template1=#', this is part of the prompt
template1=# CREATE USER gitlab_runner CREATEDB;
# Create a user for runner # Create the database & grant all privileges on database
# Do not type the 'template1=#', this is part of the prompt template1=# CREATE DATABASE nice_marmot OWNER gitlab_runner;
template1=# CREATE USER runner CREATEDB;
# Create the database & grant all privileges on database # Quit the database session
template1=# CREATE DATABASE hello_world_test OWNER runner; template1=# \q
```
# Quit the database session Try to connect to database:
template1=# \q
3. Try to connect to database: ```bash
# Try connecting to the new database with the new user
sudo -u gitlab_runner -H psql -d nice_marmot
# Try connecting to the new database with the new user # Quit the database session
sudo -u gitlab-runner -H psql -d hello_world_test nice_marmot> \q
```
# Quit the database session Finally, configure your application to use the database:
hello_world_test> \q
4. Configure your application to use the database: ```bash
Host: localhost
User: gitlab_runner
Password:
Database: nice_marmot
```
Host: localhost ## Example project
User: runner
Password: We have set up an [Example PostgreSQL Project][postgres-example-repo] for your
Database: hello_world_test convenience that runs on [GitLab.com](https://gitlab.com) using our publicly
available [shared runners](../runners/README.md).
Want to hack on it? Simply fork it, commit and push your changes. Within a few
moments the changes will be picked by a public runner and the build will begin.
