# Using Redis As many applications depend on Redis as their key-value store, 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 Redis with the Docker executor If you are using [GitLab Runner](../runners/README.md) with the Docker executor you basically have everything set up already. First, in your `.gitlab-ci.yml` add: ```yaml services: - redis:latest ``` Then you need to configure your application to use the Redis database, for example: ```yaml Host: redis ``` And that's it. Redis will now be available to be used within your testing framework. You can also use any other docker image available on [Docker Hub][hub-redis]. For example, to use Redis 2.8 the service becomes `redis:2.8`. ## Use Redis with the Shell executor Redis can also be used on manually configured servers that are using GitLab Runner with the Shell executor. In your build machine install the Redis server: ```bash sudo apt-get install redis-server ``` Verify that you can connect to the server with the `gitlab-runner` user: ```bash # Try connecting the the Redis server sudo -u gitlab-runner -H redis-cli # Quit the session 127.0.0.1:6379> quit ``` Finally, configure your application to use the database, for example: ```yaml Host: localhost ``` ## Example project We have set up an [Example Redis Project][redis-example-repo] for your 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.
