How can I provide value for the schematics_resource_crn variable?

When you run an IBM Cloud Schematics plan or apply action during Schematics infrastructure workspace setup, the resource group that you try to retrieve by using the Schematics_resource_crn cannot be found. Following error are received.

You do not have the needed permissions to use the resource group in IBM Cloud® Identity and Access Management, and provide the value for the schematics_resource_crn variable.

Check whether you have access for the Default or job-runner resource group for creating Schematics workspace for the Schematics Agent infrastructure setup. Then, you need to provide the schematics_resource_crn value to create a VPE for Schematics service by using Terraform. When the VPE is created, the Agent running in your cluster, communicates to the Schematics service over IBM Cloud private endpoint. To fetch the IBM Cloud service instance value, run ibmcloud resource service-instance schematics command.

Example : To retrieve the service instance in all resource groups from your account.

ibmcloud resource service-instance schematics

Output : From the listed output, you need to fetch the ID value for the schematics_resource_crn variable.
