Helm Release Name not Validated on Plan

[BenB196]

Terraform, Provider, Kubernetes and Helm Versions

Terraform version: 1.5.5
Provider version: 2.9.0
Kubernetes version: 1.25.12

Affected Resource(s)

• helm_release

Terraform Configuration Files

resource "helm_release" "this" {
  chart      = "raw"
  name       = "this-helm-release-name-is-longer-than-53-characters-long"
  namespace  = "default"
  repository = "https://dysnix.github.io/charts"

}

Debug Output

NOTE: In addition to Terraform debugging, please set HELM_DEBUG=1 to enable debugging info from helm.

Panic Output

N/A

Steps to Reproduce

1. terraform plan
2. terraform apply

Expected Behavior

I expect to see the plan fail with the error:

Error: release name "this-helm-release-name-is-longer-than-53-characters-long": invalid release name, must match regex ^[a-z0-9]([-a-z09]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)*$ and the length must not be longer than 53

Actual Behavior

The plan succeeds, but the apply fails with the above error.

Important Factoids

Looking through the code for helm_release I didn't see any validation functionality related to checking the resource name, so I think there just doesn't exist any provider based validation on this.

This issue isn't too bad with static release names, but can become a problem when you have 3rd parties passing names via variables.
