00 Verify Cluster

01. Installing Kind¶

• If you don’t have an existing cluster you can use google cloud for the labs hands-on

• Click on the button below to be able to run the labs on Google Shell
  [Use: CTRL + click to open in new window]

  

• Run the following commands based on your operating system:

# Install Kind using Homebrew
brew install kind

# Verify installation
kind version

# Download Kind binary
curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.20.0/kind-linux-amd64
chmod +x ./kind
sudo mv ./kind /usr/local/bin/kind

# Verify installation
kind version

# Download Kind binary
curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.20.0/kind-linux-amd64
chmod +x ./kind
sudo mv ./kind /usr/local/bin/kind

# Verify installation
kind version

02. Create Kind cluster¶

kind create cluster

• You should see an output like this:

Creating cluster "kind" ...
 • Ensuring node image (kindest/node:v1.27.3) 🖼
 • Preparing nodes 📦
 • Writing configuration 📜
 • Starting control-plane 🕹️
 • Installing CNI 🔌
 • Installing StorageClass 💾
Set kubectl context to "kind-kind"
You can now use your cluster with:

kubectl cluster-info --context kind-kind

Thanks for using kind! 😊

03. Check the Kind cluster status¶

kubectl cluster-info

• You should see output similar to this one:

Kubernetes control plane is running at https://127.0.0.1:6443
CoreDNS is running at https://127.0.0.1:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

04. Verify that the cluster is up and running¶

kubectl cluster-info

• Verify that kubectl is installed and configured

kubectl config view

• You should get something like the following

  apiVersion: v1
  clusters:
  - cluster:
      certificate-authority-data: DATA+OMITTED
      server: https://127.0.0.1:6443
    name: kind-kind
  contexts:
  - context:
      cluster: kind-kind
      user: kind-kind
    name: kind-kind
  current-context: kind-kind
  kind: Config
  preferences: {}
  users:
  - name: kind-kind
    user:
      client-certificate-data: REDACTED
      client-key-data: REDACTED
  

05. Verify that you can “talk” to your cluster¶

# Check the nodes in the Kind cluster
kubectl get nodes

• You should see output similar to this:

NAME                 STATUS   ROLES           AGE    VERSION
kind-control-plane   Ready    control-plane   2m     v1.27.3
