Grafana Helm Chart on AWS EKS, using --set for multiple service annotations-CodePudding

The grafana helm chart spawns a service on a Classic Load Balancer. I have the AWS load balancer webhook installed, and I'd like to overwrite the annotations on the Grafana service. I'm attempting the following:

helm install grafana grafana/grafana \
--namespace grafana \
--set persistence.storageClassName="gp2" \
--set persistence.enabled=true \
--set adminPassword='abc' \
--values grafana.yaml \
--set service.type=LoadBalancer \
--set nodeSelector.app=prometheus \
--set nodeSelector.k8s-app=metrics-server \
--set service.annotations."service\.beta.kubernetes\.io/aws-load-balancer-nlb-target-type"=ip \
--set service.annotations."service\.beta.kubernetes\.io/aws-load-balancer-type"=external

but, after trying multiple permutations, I continue to get:

Error: INSTALLATION FAILED: YAML parse error on grafana/templates/service.yaml: error unmarshaling JSON: while decoding JSON: json: cannot unmarshal object into Go struct field .metadata.annotations of type string

What is the correct way of doing this?

CodePudding user response：

there is an issue in the annotation, you are missing escape character for beta\.kubernetes

try this and it should work.

--set service.annotations."service\.beta\.kubernetes\.io/aws-load-balancer-nlb-target-type"=ip \
--set service.annotations."service\.beta\.kubernetes\.io/aws-load-balancer-type"=external
