minikube status

Learn the cluster status with minikube status.

minikube status

minikube status reports the state of the cluster components and whether the kubectl configuration points at this cluster:

$ minikube status
minikube
type: Control Plane
host: Running
kubelet: Running
apiserver: Running
kubeconfig: Configured

If you see kubeconfig: Misconfigured, minikube update-context fixes the kubectl setting.

Accessing the cluster

minikube ip gives the cluster's IP address. NodePort services are opened through this IP; minikube service produces the address to open directly in the browser. minikube ssh connects into the node:

$ minikube ip
192.168.49.2
$ minikube service web --url
http://192.168.49.2:31234
$ minikube ssh -- crictl ps | head -3

Practice State and access

Write three commands: show the Minikube status; print the cluster IP; print the address of the web service without opening a browser.

Starter code

terminal
# buraya yaz

Sample solution

terminal
minikube status
minikube ip
minikube service web --url

Expected output

minikube
type: Control Plane
host: Running
kubelet: Running
apiserver: Running
kubeconfig: Configured
192.168.49.2
http://192.168.49.2:31234
