Cluster Add-on: UI

node0

gcloud compute ssh node0

/opt/bin/kubectl create -f https://kuar.io/kube-ui-rc.yaml

Next create the service for the UI:

/opt/bin/kubectl create -f https://kuar.io/kube-ui-svc.yaml

At this point the Kubernetes UI add-on should be up and running. The Kubernetes API server provides access to the UI via the /ui endpoint. However the Kubernetes API is not accessable remotely due to the lack of security.

Securely Exposing the API Server

Instead of exposing the API server to the public internet over an insecure port, a SSH tunnel can be can be create between the remote client and API server.

Create a SSH tunnel between a remote client machine and the controller node:

laptop

gcloud compute ssh node0 -- -f -nNT -L 8080:127.0.0.1:8080

The UI is available at http://127.0.0.1:8080/ui on the client machine.
