1. Kubernetes create namespace with Terraform

2.1. version.tf and main.tf

#version.tf
terraform {
  required_providers {
    kubernetes = {
      source  = "hashicorp/kubernetes"
      version = "2.36.0"
    }
  }
}
provider "kubernetes" {
  config_path    = "~/.kube/config"
  config_context = "132"
}

#main.tf
resource "kubernetes_namespace" "example" {
  metadata {
    name = "my-first-namespace"
  }
}

2.2. Run terraform

terraform init terraform fmt terraform validate terraform apply -auto-approve
