Deployment
Deploy using Docker Compose:
# Go to repository with slides and demos
cd container-slides/150_gitlab/100_reverse_proxy
git pull
# Remove existing instance of GitLab
docker rm -f gitlab
# Deploy new instance
docker compose --project-name gitlab up -d
Your VM has the necessary environment variables: DOMAIN and IP
Extract password (or reset):
docker compose --project-name gitlab exec gitlab \
cat /etc/gitlab/initial_root_password \
| grep ^Password | cut -d' ' -f2

docker compose --project-name gitlab ps -a
Starting fresh (just in case)
Stop running instance:
docker compose --project-name gitlab down
Purge data by removing volumes:
docker volume rm gitlab_config
docker volume rm gitlab_logs
docker volume rm gitlab_data
docker volume create gitlab_config
docker volume create gitlab_logs
docker volume create gitlab_data
A fresh instance has a new initial root password
