- Using PostgreSQL
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.
If you are using GitLab Runner with the Docker executor you basically have everything set up already.
First, in your
services: - postgres:latest variables: POSTGRES_DB: nice_marmot POSTGRES_USER: runner POSTGRES_PASSWORD: ""
And then configure your application to use the database, for example:
Host: postgres User: runner Password: Database: nice_marmot
If you are wondering why we used
postgres for the
Host, read more at
How is service linked to the build.
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
check 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 login to PostgreSQL:
sudo -u postgres psql -d template1
Then create a user (in our case
runner) which will be used by your
$password in the command below to a real strong password.
Note: Do not type
template1=#, this is part of the PostgreSQL prompt.
template1=# CREATE USER runner WITH PASSWORD '$password' CREATEDB;
Note: Notice that we created the user with the privilege to be able to
create databases (
CREATEDB). In the following steps we will 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 on 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
Note: We are explicitly telling
psql to connect to localhost in order
to use the md5 authentication. If you omit this step you will be 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? 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.
