# Interactively

```bash
# First start a GitLab container without starting GitLab
# This is almost the same as starting the GitLab container except:
# - we run interactively (-t -i)
# - we define TERM=linux because it allows to use arrow keys in vi (!!!)
# - we choose another startup command (bash)
40
sudo docker run -ti -e TERM=linux --name gitlab_app --publish 8080:80 --publish 2222:22 --volumes-from gitlab_data gitlab_image bash
