In minikube, how to expose a service using nodeport ?
For example, I start a kubernetes cluster using the following command and create and expose a port like this:
$ minikube start
$ kubectl run hello-minikube --image=gcr.io/google_containers/echoserver:1.4 --port=8080
$ kubectl expose deployment hello-minikube --type=NodePort
$ curl $(minikube service hello-minikube --url)
CLIENT VALUES:
client_address=192.168.99.1
command=GET
real path=/ ....
Now how to access the exposed service from the host? I guess the minikube node needs to be configured to expose this port as well.
I am not exactly sure what you are asking as it seems you already know about the minikube service <SERVICE_NAME> --url
command which will give you a url where you can access the service. In order to open the exposed service, the minikube service <SERVICE_NAME>
command can be used:
$ kubectl run hello-minikube --image=gcr.io/google_containers/echoserver:1.4 --port=8080
deployment "hello-minikube" created
$ kubectl expose deployment hello-minikube --type=NodePort
service "hello-minikube" exposed
$ kubectl get svc
NAME CLUSTER-IP EXTERNAL-IP PORT(S) AGE
hello-minikube 10.0.0.102 <nodes> 8080/TCP 7s
kubernetes 10.0.0.1 <none> 443/TCP 13m
$ minikube service hello-minikube
Opening kubernetes service default/hello-minikube in default browser...
This command will open the specified service in your default browser. Here is the minikube service documentation: https://github.com/kubernetes/minikube/blob/master/docs/minikube_service.md
There is also a --url
option for printing the url of the service which is what gets opened in the browser:
$ minikube service hello-minikube --url
