|
||||
The `Assume Role ARN` field allows you to specify which IAM role to assume, if any. When left blank, the provided credentials are used directly and the associated role or user should have the required permissions. If this field is non-blank, on the other hand, the provided credentials are used to perform an [sts:AssumeRole](https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRole.html) call.
|
||||
|
||||
### Endpoint
|
||||
|
||||
The `Endpoint` field allows you to specify a custom endpoint URL that overrides the default generated endpoint for the CloudWatch API. Leave this field blank if you want to use the default generated endpoint. For more information on why and how to use Service endpoints, refer to the [AWS service endpoints documentation](https://docs.aws.amazon.com/general/latest/gr/rande.html).
|
||||
|
||||
### EKS IAM roles for service accounts
|
||||
|
||||
The Grafana process in the container runs as user 472 (called "grafana"). When Kubernetes mounts your projected credentials, they will by default only be available to the root user. In order to allow user 472 to access the credentials (and avoid it falling back to the IAM role attached to the EC2 instance), you will need to provide a [security context](https://kubernetes.io/docs/tasks/configure-pod-container/security-context/) for your pod.
