Set up a KiND cluster

How to set up a KiND cluster

前期准备

Install and configure KiND

Refer to the KiND documentation to install.

If you are using Docker Desktop, verify that you have the recommended settings.

Configure and create the KiND cluster

  1. Create a file named kind-cluster-config.yaml, and paste the following:

    kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
- role: control-plane
  kubeadmConfigPatches:
  - |
    kind: InitConfiguration
    nodeRegistration:
      kubeletExtraArgs:
        node-labels: "ingress-ready=true"    
  extraPortMappings:
  - containerPort: 80
    hostPort: 8081
    protocol: TCP
  - containerPort: 443
    hostPort: 8443
    protocol: TCP
- role: worker
- role: worker

    This cluster configuration:

    • Requests KiND to spin up a Kubernetes cluster comprised of a control plane and two worker nodes.
    • Allows for future setup of ingresses.
    • Exposes container ports to the host machine.

  2. Run the kind create cluster command, providing the cluster configuration file:

    kind create cluster --config kind-cluster-config.yaml

    预期输出

    Creating cluster "kind" ...
 ✓ Ensuring node image (kindest/node:v1.21.1) 🖼
 ✓ Preparing nodes 📦 📦 📦
 ✓ Writing configuration 📜
 ✓ Starting control-plane 🕹️
 ✓ Installing CNI 🔌
 ✓ Installing StorageClass 💾
 ✓ Joining worker nodes 🚜
Set kubectl context to "kind-kind"
You can now use your cluster with:

kubectl cluster-info --context kind-kind

Thanks for using kind! 😊

Initialize and run Dapr

  1. Initialize Dapr in Kubernetes.

    dapr init --kubernetes

    Once Dapr finishes initializing, you can use its core components on the cluster.

  2. Verify the status of the Dapr components:

    dapr status -k

  3. Forward a port to Dapr dashboard:

    dapr dashboard -k -p 9999

  4. Navigate to http://localhost:9999 to validate a successful setup.

Install metrics-server on the Kind Kubernetes Cluster

  1. Get metrics-server manifests

    wget https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml

  2. Add insecure TLS parameter to the components.yaml file

    metadata:
   labels:
     k8s-app: metrics-server
 spec:
   containers:
   - args:
     - --cert-dir=/tmp
     - --secure-port=4443
     - --kubelet-preferred-address-types=InternalIP,ExternalIP,Hostname
     - --kubelet-use-node-status-port
     - --kubelet-insecure-tls   <==== Add this
     - --metric-resolution=15s
     image: k8s.gcr.io/metrics-server/metrics-server:v0.6.2
     imagePullPolicy: IfNotPresent
     livenessProbe:
       failureThreshold: 3
       httpGet:
         path: /livez

  3. Apply modified manifest

    kubectl apply -f components.yaml
