Install and restore DTR from an existing backup
|
|
|
|
## Usage
|
|
|
|
```bash
|
|
docker run -i --rm docker/dtr \
|
|
restore [command options] < backup.tar
|
|
```
|
|
|
|
## Description
|
|
|
|
|
|
This command performs a fresh installation of DTR, and reconfigures it
|
|
with configuration data from a tar file generated by the `backup` command.
|
|
|
|
This command does not restore Docker images. You should implement a separate
|
|
restore procedure for the Docker images stored in your registry, taking in
|
|
consideration whether your DTR installation is configured to store images on
|
|
the local filesystem or using a cloud provider.
|
|
|
|
After restoring, you can add more DTR replicas by using the `join` command.
|
|
