As many applications depend on PostgreSQL as their database, you 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.
If you’re using GitLab Runner with the Docker executor, you basically have everything set up already.
First, in your
services: - postgres:12.2-alpine variables: POSTGRES_DB: nice_marmot POSTGRES_USER: runner POSTGRES_PASSWORD: "" POSTGRES_HOST_AUTH_METHOD: trust
To set values for the
assign them to a variable in the user interface,
then assign that variable to the corresponding variable in your
And then configure your application to use the database, for example:
Host: postgres User: runner Password: '' Database: nice_marmot
If you’re wondering why we used
postgres for the
Host, read more at
How services are linked to the job.
You can also use any other Docker image available on Docker Hub.
For example, to use PostgreSQL 9.3, the service becomes
postgres image can accept some environment variables. For more details,
see the documentation on Docker Hub.
You can also use PostgreSQL on manually configured servers that are using GitLab Runner with the Shell executor.
First install the PostgreSQL server:
sudo apt-get install -y postgresql postgresql-client libpq-dev
The next step is to create a user, so sign in to PostgreSQL:
sudo -u postgres psql -d template1
Then create a user (in our case
runner) which is used by your
$password in the command below to a real strong password.
template1=#in the following commands, as that’s part of the PostgreSQL prompt.
template1=# CREATE USER runner WITH PASSWORD '$password' CREATEDB;
The created user has the privilege to create databases (
following steps describe how to create a database explicitly for that user, but
having that privilege can be useful if in your testing framework you have tools
that drop and create databases.
Create the database and grant all privileges to it for the user
template1=# CREATE DATABASE nice_marmot OWNER runner;
If all went well, you can now quit the database session:
Now, try to connect to the newly created database with the user
check that everything is in place.
psql -U runner -h localhost -d nice_marmot -W
This command explicitly directs
psql to connect to localhost to use the md5
authentication. If you omit this step, you are denied access.
Finally, configure your application to use the database, for example:
Host: localhost User: runner Password: $password Database: nice_marmot
Want to hack on it? Fork it, commit, and push your changes. Within a few moments the changes are picked by a public runner and the job begins.
