## to provide grafana with access to CloudWatch on AWS EKS:
## 1. create an iam role of type "Web identity" with provider oidc.eks.* (note the provider for later)
## 2. edit the "Trust relationships" of the role, add a line inside the StringEquals clause using the
## same oidc eks provider as noted before (same as the existing line)
## also, replace NAMESPACE and prometheus-operator-grafana with the service account namespace and name
##
## "oidc.eks.us-east-1.amazonaws.com/id/XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:sub": "system:serviceaccount:NAMESPACE:prometheus-operator-grafana",
##
## 3. attach a policy to the role, you can use a built in policy called CloudWatchReadOnlyAccess
## 4. use the following env: (replace 123456789000 and iam-role-name-here with your aws account number and role name)
