I have executed minikube service mynginx1 and the result is:

 |-----------|----------|-------------|-----------------------------|
 | NAMESPACE |   NAME   | TARGET PORT |             URL             |
 |-----------|----------|-------------|-----------------------------| 
 | default   | mynginx1 | 8080-80     | http://192.168.85.153:31706 |
 |-----------|----------|-------------|-----------------------------|

What are the kubectl equivalent commands so that I can retrieve the URL if I am not using minikube?

To expose k8s application you can use kubectl expose to create service of type NodePort:

kubectl expose pod <pod_name> --type NodePort --port 8080

or 

kubectl expose deployment <deployment_name> --type NodePort --port 8080

then when you list your services you will see:

$ kubectl get services
NAME           TYPE        CLUSTER-IP     EXTERNAL-IP   PORT(S)          AGE
<service_name> NodePort    10.99.147.24   <none>        8080:31208/TCP   3s

Notice two ports under PORT column: 8080:31208/TCP. First is in-cluster port and the second is a node port. So now you can access your service with nodePort using: <node-IP>:31208 from outside of a cluster.

There is another option which only applies of you are running in cloud environment and LoadBalancers are supported (so if you are either using k8s as a service solution or running self hosted k8s in cloud with cloud provider configured). You can create a service of type LoadBalancer like following:

kubectl expose pod <pod_name> --type LoadBalacer --port 8080

$ kubectl get services
NAME             TYPE           CLUSTER-IP      EXTERNAL-IP   PORT(S)          AGE
<service_name>   LoadBalancer   10.107.151.19   x.x.x.x       8080:31111/TCP   2s

and now use EXTERNAL-IP address to connect to your service: x.x.x.x:8080

Port forward worked for me

kubectl port-forward deployment/es-manual 9200:9200
