##
## 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)
##
## env:
##   AWS_ROLE_ARN: arn:aws:iam::123456789000:role/iam-role-name-here

##   AWS_REGION: us-east-1
##
## 5. uncomment the EKS section in extraSecretMounts: below
## 6. uncomment the annotation section in the serviceAccount: above
## make sure to replace arn:aws:iam::123456789000:role/iam-role-name-here with your role arn

安装 Chart

helm fetch grafana/grafana --version 6.24.1

helm install grafana grafana/grafana --version 6.24.1 -f grafana-values.yaml -n project-grafana --debug --create-namespace

修改 values.yaml 后需要更新 Charts

helm upgrade grafana grafana/grafana --version 6.24.1 -f grafana-values.yaml -n project-grafana --debug --create-namespace

卸载 Chart

helm delete grafana
