docker/ucp backup

Estimated reading time: 1 minute

Create a backup of a UCP manager node.

Usage

docker container run --log-driver none --rm -i \
    --name ucp \
    -v /var/run/docker.sock:/var/run/docker.sock \
    docker/ucp \
    backup [command options] > backup.tar

Description

This command creates a tar file with the contents of the volumes used by this UCP manager node, and prints it. You can then use the restore command to restore the data from an existing backup.

To create backups of a multi-node cluster, you only need to back up a single manager node. The restore operation will reconstitute a new UCP installation from the backup of any previous manager.

Note:

  • The backup contains private keys and other sensitive information. Use the --passphrase flag to encrypt the backup with PGP-compatible encryption or --no-passphrase to opt out (not recommended).

  • If using the --file option, the path to the file must be bind mounted onto the container that is performing the backup, and the filepath must be relative to the container’s file tree. For example:

    docker run <other options> --mount type=bind,src=/home/user/backup:/backup docker/ucp --file /backup/backup.tar
