Helm install fails with "rendered manifests contain a resource that already exists" (ClusterRole)

I'm creating a Helm chart that can be installed in multiple namespaces. Among other resources it includes a ClusterRole.

Once the chart is installed correctly in one namespace I try to install it in another one but fails complaining about the already existing ClusterRole:

Error: rendered manifests contain a resource that already exists. Unable to continue with install: existing resource conflict: kind: ClusterRole, namespace: , name: config-reader
helm.go:76: [debug] existing resource conflict: kind: ClusterRole, namespace: , name: config-reader

What's the workaround here? Is there a way to force Helm to ignore this existing resources?

According to the documentation

ClusterRole, by contrast, is a non-namespaced resource.

If you want to define a role within a namespace, use a Role; if you want to define a role cluster-wide, use a ClusterRole.

So, Either you can use the variable name for ClusterRole or use lookup to check if the resource already exists.
