无法访问部署在 Kubernetes 系统上的应用程序 UI

Question

I have deployed a gerrit container and exposed the ports but unable to reach the UI. This is deployed on microk8s on AWS. I'm not using ingress

The Image is an official image from the docker hub.

https://hub.docker.com/r/k8sgerrit/gerrit-master

My code

apiVersion: apps/v1
kind: Deployment
metadata:
  name: gerrit-deployment
  labels:
    app: gerrit-meta
spec:
  replicas: 1
  selector:
    matchLabels:
      app: gerrit
      type: frontend
  template:

        image: k8sgerrit/gerrit
        ports:

        - containerPort: 29418

Any help to understand why the UI is not accessible is greatly appreciated.

Thank you, Anish

Managed to fix it. It was a problem with the port and the nodes were cordoned since it was running short of space
