How to Backup and Restore Docker EE UCP

Its possible to back and restore Docker EE UCP if you are running this in a production environment. One thing to note, that if you are doing a backup of UCP you must also have a backup of the Docker Swarm configuration. This can be done following this guide:

The first step is to find your UCP (id):

docker container run --rm \
  --name ucp \
  -v /var/run/docker.sock:/var/run/docker.sock \
  docker/ucp:latest \
  id

This command will push out a string like this 4tkiq0u898qlr0bvehx9g6ek2.

Once you have this id reference we can run the actual backup. Ensure to change any variables which might be different for you, such as the user profile path which is being used as a target for the backup.

docker container run \
  --log-driver none --rm \
  --interactive \
  --name ucp \
  -v /var/run/docker.sock:/var/run/docker.sock \
  docker/ucp:latest backup \
  --passphrase "Password" \
  --id 4tkiq0u898qlr0bvehx9g6ek2 > /home/it/ucp-backup.tar

Now we can run the restore using this command:

docker container run --rm -i --name ucp \

  -v /var/run/docker.sock:/var/run/docker.sock  \

  docker/ucp:latest restore --passphrase "Password" < /home/cloud_user/ucp-backup.tar

You might get faced with errors if you are trying to fix corruption in which case you have to clean up the old configuration before you attempt to restore the backup. The following command can be used to do this:

docker container run --rm -it \

  -v /var/run/docker.sock:/var/run/docker.sock \

  --name ucp \

  docker/ucp:latest uninstall-ucp --interactive
