Restore a UCP manager node from a backup

Usage


docker run -i --rm \
    --name ucp \
    -v /var/run/docker.sock:/var/run/docker.sock \
    docker/ucp \
    restore [command options] < restore.tar

Description

This command restores the state of this UCP manager node using a tar file generated by the ‘backup’ command.

The restore command stops the UCP components running on this node and restores the data from a backup, overwriting all existing data.

By default the backup tar file is read from stdin. You can also bind-mount the backup file under /config/backup.tar, and run the restore command with the ‘–interactive’ flag.

Note:

  • Before restoring a manager node, you need to stop all other managers.

  • During the restore, UCP is temporarily stopped on this node. This does not affect your applications.

  • You need to restore using a backup you created for that specific node.

Options
