Hi, Could you give me a quick hint on where I have to look for this error. I am on Windows 10 with latest version of everything on HyperV (installed through Docker Windows installation 2 days ago)

c:....fabric8\bin> gofabric8-windows-amd64.exe start --memory=2000 --cpus=2 --disk-size=10g using the executable minikube.exe running: minikube.exe start --vm-driver=hyperv --memory=2000 --cpus=2 --disk-size=10g Starting local Kubernetes cluster...

Cannot connect to api server, retrying... Cannot connect to api server, retrying... etc....

Hi similar for me on win7 entreprise. Just install fabric8 for evaluation. In VirtualBox GUI I got a running VM called minikube. when switching to VM console i got some audit logs. when asking minikube logs, i see that minikube is not able to found node info on http://127.0.0.1:8080/api/v1/nodes/minikube.

MY WORKAROUND!!! My Cisco AnyConnect VPN was killing my local Kubernetes cluster communication. Turning VPN off allowed me to follow the instructions here to get local fabric8 going: https://blog.fabric8.io/a-busy-java-developers-guide-to-developing-microservices-on-kubernetes-and-docker-98b7b9816fdf One Caveat: the fabric8 service is not exposed; I add "nodePort : 31000" and change to "type : NodePort"

It would be nice to have my kubernetes and my VPN too!

Hi all,

I have fixed the issue. It is a proxy issue. I have to setup no_proxy with the VB ip. you can run minikube ip to get the ip then set no_proxy=localhost,127.0.0.1,[VM_IP]
