### Read-only mode
If the `readonly` parameter in the `maintenance` section is set to true, clients
will not be allowed to write to the registry. This mode is useful to temporarily
prevent writes to the backend storage so a garbage collection pass can be run.
Before running garbage collection, the registry should be restarted with
`readonly` set to true. After the garbage collection pass finishes, the registry
may be restarted again, this time with `readonly` removed from the configuration.
