It was a kind 😆 of weird, handle all the Kubernetes (k8s) commands on my local environment and then I decided to install the k8s dashboard.

Expected result

What kind of problem the dashboard solve?

Solve the problem to see a GUI instead of CLI. Although help when you’re starting on k8s and/or won’t have in mind all k8s commands, there are so many, check it out.

Assumptions

login page

4. Create an authentication token

For it, deploy the content below, saving it as file, such as service-account.yml
