After you create an instance, you can edit the instance at any time to change its settings. For information about instance settings and how changing settings can impact an instance, see Instance Settings.
To edit an instance:
command and specify the flags for the settings you want to edit.
For example, the following command modifies the backup start time.
gcloud sql instances patch [INSTANCE_NAME] --backup-start-time 16:00
If the patch modifies a value that requires your instance to be restarted, you will be prompted to proceed with the change or cancel.
For details about all the options you can specify in the
instances patch command,
gcloud sql instances patch --help or see the
command in the Cloud SDK documentation.
