I installed microk8s on my ubuntu machine based on steps here https://ubuntu.com/kubernetes/install#single-node
Then I followed kubernetes official tutorial and created and exposed a deployment like this
microk8s.kubectl create deployment kubernetes-bootcamp --image=gcr.io/google-samples/kubernetes-bootcamp:v1
microk8s.kubectl expose deployment/kubernetes-bootcamp --type=NodePort --port 8083This is my kubectl get services output
akila@ubuntu:~$ microk8s.kubectl get services
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
kubernetes ClusterIP 10.152.183.1 <none> 443/TCP 25h
kubernetes-bootcamp NodePort 10.152.183.11 <none> 8083:31695/TCP 17sThis is my kubectl get pods output
akila@ubuntu:~$ microk8s.kubectl get pods
NAME READY STATUS RESTARTS AGE
kubernetes-bootcamp-6f6656d949-rllgt 1/1 Running 0 51mBut I can't access the service from my browser using http://localhost:8083 OR using http://10.152.183.11:31695
When I tried http://localhost:31695 I'm getting ERR_CONNECTION_REFUSED.
How can I access this "kubernetes-bootcamp" service from my browser ? Am I mising anything ?
The IP 10.152.183.11 is CLUSTER-IP and not accessible from outside the cluster i.e from a browser. You should be using http://localhost:31695 where 31695 is the NodePort opened on the host system.
The container of the gcr.io/google-samples/kubernetes-bootcamp:v1 image need to listen on port 8083 because you are exposing it on that port. Double check that because otherwise this will lead to ERR_CONNECTION_REFUSED error.
If the container is listening on port 8080 then use below command to expose that port
microk8s.kubectl expose deployment/kubernetes-bootcamp --type=NodePort --port 8080Try this
kubectl port-forward <pod_name> <local_port>:<pod_port> then access http://localhost:<local_port>
