Debian – URL of the pod deployed in Kind cluster is not working

• I have dockerized a simple spring boot rest api app which lists the
  employees for /employee endpoint.

• I have created a helm chart and updated the values.yml with the image
  name, service type as NodePort and service port as 31234.

• The app is configured to run on port 8085

• Created a local docker registry in localhost 5001 and pushed the
  image to this registry. So the image name under values.yml is localhost:5001/emp and tag is latest.

• kubectl get nodes -o wide gives:

test-dev-control-plane Ready control-plane 2d23h v1.27.3 172.18.0.3 Debian GNU/Linux 11 (bullseye) 5.15.133.1-microsoft-standard-WSL2 containerd://1.7.1

test-dev-worker Ready 2d23h v1.27.3 172.18.0.5 Debian GNU/Linux 11 (bullseye) 5.15.133.1-microsoft-standard-WSL2 containerd://1.7.1

test-dev-worker2 Ready 2d23h v1.27.3 172.18.0.2 Debian GNU/Linux 11 (bullseye) 5.15.133.1-microsoft-standard-WSL2 containerd://1.7.1

• kubectl get services:

NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE

emp1-chart NodePort 10.96.181.143 31234:30296/TCP 2d19h
kubernetes ClusterIP 10.96.0.1 443/TCP 2d23h

• kubectl get pods:

NAME READY STATUS RESTARTS AGE

abc 1/1 Running 1 (6m20s ago) 2d19h

• So when I try these url they are not working:

http://172.18.0.2:31234/employee

http://172.18.0.3:31234/employee

http://172.18.0.5:31234/employee

I can see the image in the node using the commands:

• kubectl get nodes
• docker exec -ti test-dev-worker bash
• crictl images

It lists the image:

localhost:5001/employee1 latest f784fbf148a06 532MB
