| # Primary Metadata Region | ||
|
|
||
| This module retrieves the `primary_metadata_region` value from the IBM Cloud Metrics Routing Account Settings. | ||
|
|
||
| ### Customizing default cloud service endpoints | ||
|
|
||
| The user must export the endpoint as an environment variable in order to use custom cloud service endpoints with this module. [Learn more](https://registry.terraform.io/providers/IBM-Cloud/ibm/latest/docs/guides/custom-service-endpoints#getting-started-with-custom-service-endpoints). | ||
|
|
||
| **Important** The only supported method for customizing cloud service endpoints is to export the environment variables endpoint; be sure to export the value for `IBMCLOUD_METRICS_ROUTING_API_ENDPOINT`. For example, | ||
|
|
||
| ``` | ||
| export IBMCLOUD_METRICS_ROUTING_API_ENDPOINT="<endpoint_url>" | ||
| ``` | ||
|
|
||
| ## Usage | ||
|
|
||
| ```hcl | ||
| provider "ibm" { | ||
| ibmcloud_api_key = "XXXXXXXXXXXXXXXXXXXXXXXX" # pragma: allowlist secret | ||
| } | ||
| module "metrics_router" { | ||
| source = "terraform-ibm-modules/cloud-monitoring/ibm//modules/get_primary_metadata_region" | ||
| region = "us-south" | ||
| use_private_endpoint = false | ||
| } | ||
