You have a custom role implemented for administration of the dev/test environment for cymbal superstore's transportation management application. You are developing a pilot to use cloud run instead of cloud functions. You want to ensure your administrators have the correct access to the new resources. What should you do?

Here are the steps you can take to ensure your administrators have the correct access to the new resources in Cloud Run:

1. Make sure that the administrators' Google Cloud IAM console permissions are appropriate. You can check the IAM & admin > Roles page in the Google Cloud console. The administrators should have the Cloud Run Admin role.
2. If the administrators do not have the Cloud Run Admin role, you can create a new custom role just for Cloud Run administration. To do this, follow these steps:
   • Go to the IAM & admin > Roles page in the Google Cloud console.
   • Click the Create custom role button.
   • Give the role a name, such as Cloud Run Administrator.
   • Select the permissions that you want to grant to the role. For example, you can grant the role permissions to create, update, and delete Cloud Run services.
   • Click the Create button.
3. Once you have created the custom role, you can add the administrators. To do this, follow these steps:
   • Go to the IAM & admin > IAM users page in the Google Cloud console.
   • Select the administrators that you want to add to the role.
   • Click the Add role button.
   • Select the role that you created in the previous step.
   • Click the Add button.
4. Once you have added the administrators to the role, they will have the correct access to the new resources in Cloud Run.

According to Google Cloud’s documentation on Cloud Run access control, you can manage access to your Cloud Run services by granting roles to users and service accounts. You can use the predefined Cloud Run IAM roles or create custom roles that grant specific permissions.
The existing role can be copied, permissions added, and the old role deleted to ensure administrators have access to the new resources correctly.
