⚠️ Archived

This repository was experimental and is now archived. The kubernetes_manifest resource and associated issues has been moved to the repository for the official Terraform Provider for Kubernetes. While the kubernetes-alpha provider will continue to be downloadable from the Terraform Registry up to the last version released, we recommend migrating your configurations to use the kubernetes_manifest resource in our official Terraform provider. For further details, take a look at our blog post announcing this change.

Kubernetes provider for Terraform (alpha)

Terraform logo

Status: Experimental Releases LICENSE unit tests acceptance tests

This Kubernetes provider for Terraform (alpha) supports all API resources in a generic fashion.

This provider allows you to describe any Kubernetes resource using HCL. See Moving from YAML to HCL if you have YAML you want to use with the provider.

Please regard this project as experimental. It still requires extensive testing and polishing to mature into production-ready quality. At this time, we are not planning to create a migration path for resources created with the kubernetes-alpha provider when the manifest resource is merged into the official kubernetes provider. For this reason, please do not rely on this provider for production use while we strive towards project maturity. Please file issues generously and detail your experience while using the provider. We welcome your feedback.

Our eventual goal is for this generic resource to become a part of our official Kubernetes provider once it is supported by the Terraform Plugin SDK. However, this work is subject to signficant changes as we iterate towards that level of quality.


Getting Started

If this is your first time here, you can get an overview of the provider by reading our introductory blog post.

Otherwise, start by installing the latest release from the Terraform registry.

Once you have the plugin installed, review the usage document in the docs folder to understand which configuration options are available. You can find the following examples and more in our examples folder. Don't forget to run terraform init in your Terraform configuration directory to allow Terraform to detect the provider plugin.

Create a Kubernetes ConfigMap

provider "kubernetes-alpha" {
  config_path = "~/.kube/config" // path to kubeconfig

resource "kubernetes_manifest" "test-configmap" {
  provider = kubernetes-alpha

  manifest = {
    "apiVersion" = "v1"
    "kind" = "ConfigMap"
    "metadata" = {
      "name" = "test-config"
      "namespace" = "default"
    "data" = {
      "foo" = "bar"

Create a Kubernetes Custom Resource Definition

provider "kubernetes-alpha" {
  config_path = "~/.kube/config" // path to kubeconfig

resource "kubernetes_manifest" "test-crd" {
  provider = kubernetes-alpha

  manifest = {
    apiVersion = ""
    kind = "CustomResourceDefinition"
    metadata = {
      name = ""
    spec = {
      group = ""
      names = {
        kind = "TestCrd"
        plural = "testcrds"
      scope = "Namespaced"
      versions = [{
        name = "v1"
        served = true
        storage = true
        schema = {
          openAPIV3Schema = {
            type = "object"
            properties = {
              data = {
                type = "string"
              refs = {
                type = "number"

Using wait_for to block create and update calls

The kubernetes_manifest resource supports the ability to block create and update calls until a field is set or has a particular value by specifying the wait_for attribute. This is useful for when you create resources like Jobs and Services when you want to wait for something to happen after the resource is created by the API server before Terraform should consider the resource created.

wait_for currently supports a fields attribute which allows you specify a map of fields paths to regular expressions. You can also specify * if you just want to wait for a field to have any value.

resource "kubernetes_manifest" "test" {
  provider = kubernetes-alpha

  manifest = {
    // ...

  wait_for = {
    fields = {
      # Check the phase of a pod
      "status.phase" = "Running"

      # Check a container's status
      "status.containerStatuses[0].ready" = "true",

      # Check an ingress has an IP
      "status.loadBalancer.ingress[0].ip" = "^(\\d+(\\.|$)){4}"

      # Check the replica count of a Deployment
      "status.readyReplicas" = "2"

      # Check for an annotation
      "metadata.annotations[\"test.annotation\"]" = "*"

Moving from YAML to HCL

The manifest attribute of the kubernetes_manifest resource accepts any arbitrary Kubernetes API object, using Terraform's map syntax. If you have YAML you want to use with this provider, we recommend that you convert it to a map as an initial step and then manage that resource in Terraform, rather than using yamldecode() inside the resource block.

You can quickly convert a single YAML file to an HCL map using this one liner:

echo 'yamldecode(file("test.yaml"))' | terraform console

Alternatively, there is also an experimental command line tool tfk8s you could use to convert Kubernetes YAML manifests into complete Terraform configurations.


We welcome your contribution. Please understand that the experimental nature of this repository means that contributing code may be a bit of a moving target. If you have an idea for an enhancement or bug fix, and want to take on the work yourself, please first create an issue so that we can discuss the implementation with you before you proceed with the work.
