How Do We Access the Kubernetes Dashboard in Minikube?
To access the Kubernetes Dashboard in Minikube, we can follow these steps:
Start Minikube: First, we need to make sure our Minikube cluster is running. We can start it by using:
minikube start
Enable the Dashboard: Next, we use this command to enable the Kubernetes Dashboard:
minikube dashboard
This command will open the Dashboard in our default web browser.
Accessing the Dashboard Manually: If we want to access the Dashboard manually, or if it does not open automatically, we can use this command to get the URL:
minikube service kubernetes-dashboard --namespace kube-system --url
This command gives us a URL like
http://192.168.99.100:30000
. We can open this in a web browser.Using Proxy (Optional): We can also access the Dashboard through the Kubernetes API server proxy:
kubectl proxy
After that, we open this URL in our browser:
http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/
Authentication: If we have RBAC enabled, we may need to create a ServiceAccount and ClusterRoleBinding to access the Dashboard:
kubectl create serviceaccount dashboard-admin -n kube-system kubectl create clusterrolebinding dashboard-admin --clusterrole=cluster-admin --serviceaccount=kube-system:dashboard-admin
Then we can get the token:
kubectl get secret $(kubectl get serviceaccount/dashboard-admin -n kube-system -o jsonpath="{.secrets[0].name}") -o jsonpath="{.data.token}" | base64 --decode
We use this token to log into the Dashboard.
By doing these steps, we can access the Kubernetes Dashboard in our Minikube setup. This helps us manage our Kubernetes resources easily. For more details on Kubernetes itself, we can check out What Are the Key Components of a Kubernetes Cluster?.
How Do I Stop and Delete a Minikube Cluster?
To stop and delete a Minikube cluster, we can use the Minikube command-line interface (CLI). Let’s follow these steps:
Stopping the Minikube Cluster: We use this command to stop the Minikube cluster:
minikube stop
This command will stop the running cluster. It does not delete it. You can start it again later when you need.
Deleting the Minikube Cluster: If we want to remove the Minikube cluster completely, we use this command:
minikube delete
This command will delete the cluster and all its resources. It will free up some disk space on our machine.
Verifying Deletion: After we delete the cluster, we can check that no clusters are left by running:
minikube status
The output should show that no Minikube cluster is running now.
With these commands, we can manage our Minikube clusters for local Kubernetes development. For more information about Kubernetes and how it works, we can check this article on what Kubernetes is and how it simplifies container management.

Yes, we can run multiple Minikube clusters on the same machine by
using different profiles for each cluster. We can use the
--profile
flag when starting Minikube to create and manage
different clusters. For example, we can run
minikube start --profile=my-cluster-1
for one cluster and
minikube start --profile=my-cluster-2
for another. This
lets us try out different setups and applications at the same time.
5. How does Minikube differ from using a full Kubernetes cluster?
Minikube gives us a small, single-node Kubernetes environment for local development. This makes it great for testing and learning. A full Kubernetes cluster has many nodes and is usually run in the cloud or in big organizations for production work. Minikube makes it easier to learn about Kubernetes. We can understand its ideas and features without the trouble of managing a full cluster. For more details on Kubernetes architecture, we can read What are the Key Components of a Kubernetes Cluster?.
