This is multi-node Kubernetes cluster running under Kubernetes in Docker
The playground contains a control plane node and two worker nodes.
Kubernetes in Docker (KinD) Playground
When you start out you might see the cluster spinning up in the teminal pane like so:
Creating cluster "kind" ... ✓ Ensuring node image (kindest/node:v1.19.1) 🖼 ✓ 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 Have a nice day! 👋
Be patient. It might take a few minutes for the cluster to spin up.
Once you see a command prompt, to confirm the cluster is up and running click the following command:
kubectl get node -o wide
You'll see output similar to the following:
NAME STATUS ROLES AGE VERSION INTERNAL-IP EXTERNAL-IP OS-IMAGE KERNEL-VERSION CONTAINER-RUNTIME kind-control-plane Ready master 2m59s v1.19.1 172.19.0.3 <none> Ubuntu Groovy Gorilla (development branch) 4.4.0-185-generic containerd://1.4.0 kind-worker Ready <none> 2m23s v1.19.1 172.19.0.2 <none> Ubuntu Groovy Gorilla (development branch) 4.4.0-185-generic containerd://1.4.0 kind-worker2 Ready <none> 2m23s v1.19.1 172.19.0.4 <none> Ubuntu Groovy Gorilla (development branch) 4.4.0-185-generic containerd://1.4.0
Once the cluster is up and running take it for a spin and enjoy!
