# runner After installation, individual runners must still be registered, e.g.: ``` docker run --rm -it -v gitlab_runner_config:/etc/gitlab-runner gitlab/gitlab-runner register --name ``` An issue I encountered when trying to cache stuff between builds was the following warning in the runner logs: ``` ERROR: Could not create cache adapter error=cache factory not found: factory for cache adapter "" was not registered ``` In order to make the runner able to create caches, register it like so: ``` docker run --rm -it -v gitlab_runner_config:/etc/gitlab-runner gitlab/gitlab-runner register --name --docker-disable-cache=false -docker-cache-dir /cache --docker-volumes gitlab_runner_cache:/cache ```
