Kubernetes UI

Open a browser and run the following code:

https://<your master ip>/ui/

The certificate is self-signed by default, so you'll need to ignore the warnings in your browser before proceeding. After this, we will see a login dialog. This is where we use the credentials listed during the K8s installation. We can find them at any time by simply using the config command:

$ kubectl config view

Now that we have credentials for login, use those, and we should see a dashboard like the following image:

The main dashboard takes us to a page with not much display at first. There is a link to deploy a containerized app that will take you to a GUI for deployment. This GUI can be a very easy way to get started deploying apps without worrying about the YAML syntax for Kubernetes. However, as your use of containers matures, it's good practice to use the YAML definitions that are checked in to source control.

If you click on the Nodes link on the left-hand side menu, you will see some metrics on the current cluster nodes:

At the top, we see an aggregate of the CPU and memory usages followed by a listing of our cluster nodes. Clicking on one of the nodes will take us to a page with detailed information about that node, its health, and various metrics.

The Kubernetes UI has a lot of other views that will become more useful as we start launching real applications and adding configurations to the cluster.
