Importing existing resources

This provider supports importing existing resources into the terraform state. Import is done according to the various provider/resource configuation settings to contact the API server and obtain data.

mimir alerting rule group

To import mimir rule group alerting The id is build as <namespace>/<name>

Example:

terraform import 'mimir_rule_group_alerting.alert1' namespace1/alert1
mimir_rule_group_alerting.alert1: Importing from ID "namespace1/alert1"...
mimir_rule_group_alerting.alert1: Import prepared!
  Prepared mimir_rule_group_alerting for import
mimir_rule_group_alerting.alert1: Refreshing state... [id=namespace1/alert1]

Import successful!

The resources that were imported are shown above. These resources are now in
your Terraform state and will henceforth be managed by Terraform.
