I setup Kubernetes cluster with Minikube and setup the JHipster microservices on Kubernetes cluster with the following commands.

WARNING! You will need to push your image to a registry. If you have not done so, use the following commands to tag and push the images:
    docker image tag books duppoc/books
    docker image push duppoc/books
    docker image tag bookstore duppoc/bookstore
    docker image push duppoc/bookstore

You can deploy all your apps by running: 
    kubectl apply -f namespace.yml  
    kubectl apply -f console
    kubectl apply -f registry
    kubectl apply -f books
    kubectl apply -f bookstore

Use these commands to find your application's IP addresses:
    kubectl get svc bookstore

After this, I tried to open Kubernetes dashboard to see all containers. I tried to follow the instructions mentioned here. However, I am getting following error

Error: 'dial tcp 172.17.0.4:9090: getsockopt: connection refused'

Based on #2691 I am able to access my dashboard using following link http://localhost:8001/api/v1/namespaces/kube-system/services/kubernetes-dashboard/proxy.

I am not sure why wasn't this http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/ working. When I click on it it throws following error

Error: 'net/http: TLS handshake timeout'

Minikube by default installs Dashboard in alternative version which means that HTTPS is disabled. They might be using addon manager to install it so it is not possible to install newer version easily.

Also kubernetes.io documentation is outdated and you should only use our official documentation available on https://github.com/kubernetes/dashboard or on our wiki pages https://github.com/kubernetes/dashboard/wiki. xxx/ui endpoint is also deprecated and will be removed in future kubernetes versions. You should use direct service proxy path to access Dashboard.
