How can I access a service installed on Kubernetes from anywhere

Question

I am trying to configure kubernetes and I have a mac machine and installed the latest Kubernetes. All went smooth but I was hoping that Kubernetes will provide me an ip address and port number where my service will be listening to so that I can access it from anywhere.

Please correct me if I am wrong.

I was able to run ifconfig as well as curl $(minikube service hello-minikube --url) and I was able to see the ip address and port but I wasn’t able to access it outside command line where Kubernetes lives in.

The reason I am trying to access it outside the VM is because we have other projects that run on other machines and I wanted to call the REST service I installed while we are on dev env. This way we don’t have to wait until the service is pushed to production.

Can anyone help me with this ?

Answer 1

I have followed the link which you have attached and it works as expected.

Here is a command which you can use:

minikube service hello-minikube --url

You will get a url like http://192.168.99.100:32382/ - the port and IP could and will change for you. Also note that the exposed port will be a random port like the 32382 and not 8080 that the pod uses.

Use the url in your browser, say and you should be able to see the output of the service.

I hope the information would be helpful for you.

if u want to directly want to access your service u need to expose them via  a node port

apiVersion: v1
kind: Service
metadata:
  name: app-server
  labels:
    name: app-server
spec:
  type: NodePort
  sessionAffinity: ClientIP
  ports:
    - port: 443 # application Port
      nodePort: 31000 # external application access port of your choice
      protocol: TCP
      name: app-server-port
  selector:
    name: app-server # your deployment selector whatever your define your deployment name
