I am working on creating a nexus repo through kubernetes. By browesing i came across this site (https://blog.sonatype.com/kubernetes-recipe-sonatype-nexus-3-as-a-private-docker-registry) I was able to create a service and deployment and pod and everthing created without am issue. But i was not able to open it.

This is my nexus.yaml file

apiVersion: v1

  name: nexus

        - containerPort: 5000
        volumeMounts:
          - mountPath: /nexus-data
            name: nexus-data-volume
      volumes:

          persistentVolumeClaim:
            claimName: nexusvolume-local

      - path: /
        backend:

When i give
kubectl describe service nexus-service -n nexus
