How to Log in to the Microk8s Kubernetes Dashboard: A Guide for Data Scientists
In the world of data science, Kubernetes has become a cornerstone for managing and orchestrating containerized applications. Microk8s, a lightweight, simplified version of Kubernetes, is gaining popularity due to its ease of use and minimal resource requirements. One of the key features of Microk8s is its built-in dashboard, a user-friendly interface for managing your Kubernetes cluster. In this blog post, we’ll guide you through the process of logging in to the Microk8s Kubernetes Dashboard.
Prerequisites
Before we begin, ensure you have the following:
- A running Microk8s cluster. If you haven’t set this up yet, follow the official Microk8s installation guide.
kubectl, the Kubernetes command-line tool. You can download it from the official Kubernetes website.
Step 1: Enable the Dashboard
Microk8s doesn’t enable the dashboard by default. To enable it, run the following command:
microk8s enable dashboard
This command will install and configure the Kubernetes Dashboard, Heapster, Grafana, and InfluxDB.
Step 2: Access the Dashboard
The Microk8s dashboard isn’t exposed externally by default. To access it, we’ll use a secure channel called a Kubernetes proxy. Run the following command:
microk8s kubectl proxy
Now, you can access the dashboard at the following URL: http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/.
Step 3: Obtain the Login Token
The Kubernetes Dashboard requires a token for login. To get this token, we’ll create a service account and cluster role binding. Run the following commands:
microk8s kubectl create serviceaccount dashboard-admin -n default
microk8s kubectl create clusterrolebinding dashboard-admin-role --clusterrole=cluster-admin --serviceaccount=default:dashboard-admin
Next, get the token for the dashboard-admin service account:
microk8s kubectl get secret $(microk8s kubectl get serviceaccount dashboard-admin -o jsonpath="{.secrets[0].name}") -o jsonpath="{.data.token}" | base64 --decode
This command will output a long string of characters—this is your login token.
Step 4: Log in to the Dashboard
Go back to the dashboard URL. You’ll see a login screen asking for a token. Paste the token you obtained in the previous step and click “SIGN IN”.
Congratulations! You’re now logged in to the Microk8s Kubernetes Dashboard.
Conclusion
The Microk8s Kubernetes Dashboard is a powerful tool for managing your Kubernetes cluster. With this guide, you should be able to log in to the dashboard and start exploring its features. Remember, while the dashboard is a great tool, it’s important to also be comfortable with kubectl and the command line for more complex tasks.
