Kubernetes minikube, cannot expose service on public ip range

Question

So I've been playing around with Minkube.

I've managed to deploy a simple python flask container:

PS C:\Users\Will> kubectl run test-flask-deploy --image 
192.168.1.201:5000/test_flask:1 
deployment "test-flask-deploy" created

I've also then managed to expose the deployment as a service:

PS C:\Users\Will> kubectl expose deployment/test-flask-deploy --
type="NodePort" --port 8080
service "test-flask-deploy" exposed

In the dashboard I can see that the service has a Cluster IP: 10.0.0.132.

I access the dashboard on a 192.168.xxx.xxx address, so I'm hoping I can expose the service on that external IP.

Any idea how I go about this?

A separate and slightly less important question: I've got minikube talking to a docker registry on my network. If i deploy an image (which has not yet been pulled local to the minikube) the deployment fails, yet when I run the docker pull command on minikube locally, the deployment then succeeds. So minikube is able to pull docker images, but when I deploy an image which is accessible via the registry, yet not pulled locally, it fails. Any thoughts?

Answer 1

First, check the nodeport that is assigned to your service:

$ kubectl get svc test-flask-deploy
NAME                CLUSTER-IP   EXTERNAL-IP   PORT(S)          AGE
test-flask-deploy   10.0.0.76    <nodes>       8080:30341/TCP   4m

Now you should be able to access it on 192.168.xxxx:30341 or whatever your minikubeIP:nodeport is.
