An IAM user that is granted access to ALB Ingress resources by the Volcano Engine root user encounters a 403 error when accessing ALB Ingress resources.

Cause

Accessing ALB Ingress resources requires ALBInstance access. ALBInstance is a cluster-level resource, and the corresponding resource-level access must be enabled.

When the IAM user is granted access to ALB Ingress resources by using the console, if a specific namespace is specified, the IAM user can only access resources in the namespace.

Solution

Enable access to ALBInstance resources (cluster-level resources). For detailed steps, see How do I grant cluster-level resource permissions to IAM users?
