Install command:
helm install aws-node-termination-handler --namespace kube-system --values values.yaml eks/aws-node-termination-handler
When installing aws-node-termination-handler from the helm chart I am getting the following error:
Error: DaemonSet.apps "aws-node-termination-handler" is invalid: [spec.template.spec.volumes[1].name: Invalid value: "webhookTemplate": a DNS-1123 label must consist of lower case alphanumeric characters or '-', and must start and end with an alphanumeric character (e.g. 'my-name', or '123-abc', regex used for validation is '[a-z0-9]([-a-z0-9]*[a-z0-9])?'), spec.template.spec.containers[0].volumeMounts[1].name: Not found: "webhookTemplate"]
As the error suggest a volume name cannot contain an upper case character. If I output the helm output to yaml and change the webhookTemplate volume name so that it does not contain an upper case, it applies fine.
