Can't pass AdditionalCommandArgs to barman-cloud-restore

[an-tex]

you can pass custom command line arguments to the backup and wal-restore commands but not to barman-cloud-restore.

default options are pulled in from barmanCommand.AppendCloudProviderOptionsFromConfiguration and then some custom ones are added.

	var options []string

	options, err := barmanCommand.AppendCloudProviderOptionsFromConfiguration(ctx, options, barmanConfiguration)
	if err != nil {
		return err
	}

	if backup.Status.EndpointURL != "" {
		options = append(options, "--endpoint-url", backup.Status.EndpointURL)
	}
	options = append(options, backup.Status.DestinationPath)
	options = append(options, backup.Status.ServerName)
	options = append(options, backup.Status.BackupID)
	options = append(options, impl.PgDataPath)

	log.Info("Starting barman-cloud-restore",
		"options", options)

but neither is taking e.g. /spec/configuration/data/additionalCommandArgs/ or other appropriate keys into account.

in our case I'd like to pass a custom read timeout

Hi @an-tex! I'm Dosu and I’m helping the plugin-barman-cloud team.

You're correct — this is a confirmed gap in the plugin. While additionalCommandArgs is supported for backup (data.additionalCommandArgs) and WAL restore (wal.restoreAdditionalCommandArgs), there's no equivalent field for barman-cloud-restore.

The restoreDataDir function builds its options only from AppendCloudProviderOptionsFromConfiguration without incorporating any additional command args configuration.

Related: Issue #783 confirms this limitation — additionalCommandArgs only applies to backup operations, not restore.

To implement this, it would likely require:

1. Adding a new configuration field (e.g., data.restoreAdditionalCommandArgs) to the CRD manifest
2. Updating the restoreDataDir function to append those args when building the command

For your use case (custom read timeout), this would be a valid feature request.

To reply, just mention @dosu.
