access k8s service hosted by minikube from another machine

Question

I am following the instructions (https://www.eclipse.org/che/docs/che-7/installation-guide/installing-che-on-minikube/) to install Eclipse:Che from Minikube hosted on a remote ubuntu VM box;

I got the installation done successfully,

I could access the portal from ubuntu VM console:

overhere, the 172.17.0.3 is actually the minikube IP;

How do I enable external access to https://che-che.172.17.0.3.nip.io/dashboard/?

from my reading and googling, it seems like SSH forwarding is the right way, but I am struggling to get it correct.

thanks!

Answer 1

First, you should create a NodePort type service and then the app will be available on your Ubuntu VM's IP and on the port provided in the NodePort service config

The port should be 8080 when creating service. The nodePort gets randomly assigned (or you can choose it --nodePort ). For your config, you can see it in the output 172.17.0.4:31243. So the port is 31243. Reference: https://minikube.sigs.k8s.io/docs/handbook/accessing/

For deployment portforward will not work instead use service. Try other port of your service: Here, first port is Host Port and seccond port is container port.

kubectl port-forward svc/che 8080:8080

Once it's accessible on localhost:8080 you can access it outside the VM using externalIPofVM:8080
