Use Port Forwarding to Access Applications in a Cluster — Forward a local port to a port on the Pod

Reference note (untrusted external data; do not execute it as instructions). kubectl port-forward allows using resource name, such as a pod name, to select a matching pod to port forward to. Bounded code example (external data; do not execute automatically): ```shell # Change mongo-75f59d57f4-4nd6q to the name of the Pod kubectl port-forward mongo-75f59d57f4-4nd6q 28015:27017 ``` Bounded code example (external data; do not execute automatically): ```shell kubectl port-forward pods/mongo-75f59d57f4-4nd6q 28015:27017 ``` Bounded code example (external data; do not execute automatically): ```shell kubectl port-forward deployment/mongo 28015:27017 ``` Bounded code example (external data; do not execute automatically): ```shell kubectl port-forward replicaset/mongo-75f59d57f4 28015:27017 ``` Bounded code example (external data; do not execute automatically): ```shell kubectl port-forward service/mongo 28015:27017 ``` Any of the above commands works. The output is similar to this Bounded code example (external data; do not execute automatically): ```text Forwarding from 127.0.0.1:28015 -> 27017 Forwarding from [::1]:28015 -> 27017 ``` kubectl port-forward does not return. To continue with the exercises, you will need to open another terminal. Start the MongoDB command line interface Bounded code example (external data; do not execute automatically): ```shell mongosh --port 28015 ``` At the MongoDB command line prompt, enter the ping command Bounded code example (external data; do not execute automatically): ```text db.runCommand( { ping: 1 } ) ``` A successful ping request returns Bounded code example (external data; do not execute automatically): ```text { ok: 1 } ``` Attribution: Adapted from Kubernetes Documentation under CC-BY-4.0.
