The draining function's IAM policy does not provide enough permission to change the ECS instance state.

  • What is the current behavior?
    The ecs:UpdateContainerInstancesState permission is provided for the cluster ARN but the function needs to set the state on the instance which has a different ARN.
An error occurred (AccessDeniedException) when calling the UpdateContainerInstancesState operation: User: arn:aws:sts::assumed-role/[role]/[function] is not authorized to perform: ecs:UpdateContainerInstancesState on resource: arn:aws:ecs:ap-southeast-2::container-instance/[instance]

  • What is the expected behavior (or behavior of feature suggested)?
    The function should have access to the cluster instance to set the state.

  • What is the motivation / use case for changing the behavior or adding this feature?
    The draining function can't set the instance to draining which defeats its sole purpose.

  • Please tell us about your environment:

    • CDK CLI Version: 0.36.1
    • Module Version: 0.36.1
    • OS: Linux
    • Language: TypeScript

UpdateContainerInstancesState and ListTasks need to be restricted to the containerInstance resource.

Thank you for pointing out the documentation! Looks like the ARN format defined in the documentation refers to the long ARN @pkandasamy91. The legacy format does not have the cluster name.

UPDATE:
I tried with a cluster opted-in for the long ARN and the container instance does not have the cluster name in its ARN.
@pkandasamy91 could you please verify that the linked AWS documentation has the correct ARN format for the container instance?

The UpdateContainerInstancesState permission was scoped to the ECS cluster
while it should be scoped to the container instance.

UpdateContainerInstanceState and ListTask APIs require permissions on
a container-instance resource, rather than a cluster resource. This
change updates the policy to:

1. remove the cluster as the resource restriction
2. add the cluster as a resource condition

@ScOut3R thanks for the feedback! Instead of using the resource arn (which would vary depending on if you opted into using long arns or not), we used the cluster as the condition key for restricting the scope of the permissions on ListTasks and UpdateContainerInstancesState actions.

The fix has been merged in!
