These are the docs for DTR version 2.3.8
To select a different version, use the selector below.
Create a backup of DTR
docker run --log-driver none -i --rm docker/dtr \ backup [command options] > backup.tar
This command creates a tar file with the contents of the volumes used by DTR, and prints it. You can then use the ‘restore’ command to restore the data from an existing backup.
This command only creates backups of configurations, and image metadata. It doesn’t back up users and organizations. Users and organizations can be backed up when performing a UCP backup.
It also doesn’t back up the Docker images stored in your registry. You should implement a separate backup policy for the Docker images stored in your registry, taking in consideration whether your DTR installation is configured to store images on the filesystem or using a cloud provider.
This backup contains sensitive information and should be stored securely.
||$DEBUG||Enable debug mode for additional logs.|
||$ENZI_TLS_CA||Use a PEM-encoded TLS CA certificate for Enzi.|
||$ENZI_TLS_INSECURE||Disable TLS verification for Enzi.|
||$DTR_REPLICA_ID||The ID of an existing DTR replica. To safely remove a DTR replica from the cluster, the remove command needs to notify a healthy replica about the replica that’s about to be removed.|
||$DTR_EXTENDED_HELP||Display extended help text for a given command.|
||$UCP_CA||Use a PEM-encoded TLS CA certificate for UCP. Download the UCP TLS CA certificate from https://
||$UCP_INSECURE_TLS||Disable TLS verification for UCP. The installation uses TLS but always trusts the TLS certificate used by UCP, which can lead to man-in-the-middle attacks. For production deployments, use --ucp-ca “$(cat ca.pem)” instead.|
||$UCP_PASSWORD||The UCP administrator password.|
||$UCP_URL||The UCP URL including domain and port.|
||$UCP_USERNAME||The UCP administrator username.|
