Trouble following tutorial Using a Service to Expose Your App

[joeythomaschaske]

Following the steps here I get to the step where I create a NodePort service and use curl to access it.

Now we can test that the app is exposed outside of the cluster using curl, the IP address of the Node and the externally exposed port:

curl http://"$(minikube ip):$NODE_PORT"

And we get a response from the server. The Service is exposed.

I do not get a response and eventually get the error

curl: (28) Failed to connect to 192.168.49.2 port 30140 after 75007 ms: Couldn't connect to server

Additionally the docs say there should be an external IP assigned after adding a NodePort service

We have a Service called kubernetes that is created by default when minikube starts the cluster. To create a new service and expose it to external traffic we'll use the expose command with NodePort as parameter.

kubectl expose deployment/kubernetes-bootcamp --type="NodePort" --port 8080

Let's run again the get services subcommand:

kubectl get services

We have now a running Service called kubernetes-bootcamp. Here we see that the Service received a unique cluster-IP, an internal port *and an external-IP (the IP of the Node).*

However I don't see this

% kubectl get services
NAME                  TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)          AGE
kubernetes            ClusterIP   10.96.0.1        <none>        443/TCP          160m
kubernetes-bootcamp   NodePort    10.107.221.142   <none>        8080:30552/TCP   6m8s

Running minikube service kubernetes-bootcamp does work to expose it though
