A GitHub Action for starting a Kubernetes cluster with a local registry and optional addons (Knative) using KinD.

This action provides an insecure registry on kind-registry:5000 by default: it can be used to publish and deploy container images into KinD.

Create a workflow YAML file in your .github/workflows directory. An example workflow is available below. For more information, reference the GitHub Help Documentation for Creating a workflow file.

For more information on inputs, see the API Documentation

• version: The KinD version to use (default: v0.17.0)
• config: The path to the KinD config file
• node_image: The Docker image for the cluster nodes
• cluster_name: The name of the cluster to create (default: kind)
• wait: The duration to wait for the control plane to become ready (default: 60s)
• log_level: The log level for KinD
• registry: Configures an insecure registry on kind-registry:5000 to be used with KinD (default: true)
• registry_delete: Set to true to enable delete operations on the Image Registry (default is false)
• kubectl_version: The kubectl version to use (default: v1.26.1)
• knative_serving: The version of Knative Serving to install on the Kind cluster (not installed by default - example: v1.0.0)
• knative_kourier: The version of Knative Net Kourier to install on the Kind cluster (not installed by default - example: v1.0.0)
• knative_eventing: The version of Knative Eventing to install on the Kind cluster (not installed by default - example: v1.0.0)
• cpu: Number of CPUs to be allocated to the virtual machine (default: 2). For Mac OS only.
• memory: Size of the memory in GiB to be allocated to the virtual machine (default: 12). For Mac OS only.
• disk: Size of the disk in GiB to be allocated to the virtual machine (default: 60). For Mac OS only.

Create a workflow (eg: .github/workflows/create-cluster.yml):

name: Create Cluster

on: pull_request

jobs:
  create-cluster:
    runs-on: ubuntu-latest
    steps:
      - name: Kubernetes KinD Cluster
        uses: container-tools/kind-action@v1

This uses @container-tools/kind-action GitHub Action to spin up a KinD Kubernetes cluster on every Pull Request.

A container registry will be created with address kind-registry:5000 on both the host and the cluster. The registry address is stored in the KIND_REGISTRY environment variable, also for the subsequent steps.

Create a workflow (eg: .github/workflows/create-cluster-with-addons.yml):

name: Create Cluster with Addons

on: pull_request

jobs:
  create-cluster-with-addons:
    runs-on: ubuntu-latest
    steps:
      - name: Kubernetes KinD Cluster
        uses: container-tools/kind-action@v1
        with:
          knative_serving: v1.0.0
          knative_kourier: v1.0.0
          knative_eventing: v1.0.0

This will install Knative Serving, Eventing and a Kourier Ingress on your Kind cluster. To make Knative run on Kind, resource request and limits are removed from the original Knative descriptors.

This action leverages the good work done by the Helm community on @helm/kind-action.
