Custom Role Cloudsql Recommender Group

What Custom IAM Roles for Cloud SQL Are

Custom IAM roles allow organizations to group user-defined collections of granular permissions that tailor access precisely to operational requirements when predefined roles grant excess privileges.

How It Meets the Requirements

• Principle of least privilege: It strips out administrative permissions (such as instance deletion, replica modifications, database user changes, and backup restores) that roles/cloudsql.admin grants, providing only read and security-recommender permissions.
• Console usability: Google Cloud console requires paired permissions to render Cloud SQL instances properly. When granting access to view instances, both cloudsql.instances.list and cloudsql.instances.get must be included in custom roles; otherwise, navigation fails.
• Recommender insights: Incorporating recommender.cloudsqlInstanceSecurityInsights.get, recommender.cloudsqlInstanceSecurityInsights.list, recommender.cloudsqlInstanceSecurityRecommendations.get, and recommender.cloudsqlInstanceSecurityRecommendations.list enables the group to assess security vulnerabilities without unnecessary management permissions.
• Group-based management: Binding the role directly to dba-team@example.com enforces consistent authorization across all database team members through identity federation or Cloud Identity.

Key Advantages

• Eliminates excessive privileges: Prevents accidental instance modification, deletion, or data export.
• Maintains seamless UI experience: Avoids HTTP 403 authorization errors inside the Google Cloud console.
• Streamlines security posture auditing: Allows the operations team to evaluate security recommendations continuously.
• Centralizes identity lifecycle: Group-based binding avoids individual member configuration drift.

Why This Is Optimal

Creating a tailored custom role containing the necessary instance read and recommender permissions—while adhering to the list and get pairing requirement—strictly fulfills least privilege without disrupting day-to-day administrative visibility.
