Terraform provider: Helm

https://registry.terraform.io/providers/hashicorp/helm/latest/docs

Examples

provider "helm" {}

provider "helm" {
  kubernetes {
    config_path = "~/.kube/config"
  }
}

provider "helm" {
  kubernetes {
    config_path = "~/.kube/config"
    config_context = "my-context-cluster"
  }
}

Official example in EKS module deployed with Karpenter

 provider "helm" {
 kubernetes {
   host                   = module.eks.cluster_endpoint
   cluster_ca_certificate = base64decode(module.eks.cluster_certificate_authority_data)

   exec {
     api_version = "client.authentication.k8s.io/v1beta1"
     command     = "aws"
     # This requires the awscli to be installed locally where Terraform is executed
     args = ["eks", "get-token", "--cluster-name", module.eks.cluster_name]
   }
 }
}
