Accessing running pods

You can review running pods dynamically by opening a shell inside a pod or by gaining network access through port forwarding.

Prerequisites

  • You have access to the cluster as a user with the cluster-admin role.

  • Your API service is still functional.

  • You have installed the OpenShift CLI (oc).

Procedure

  1. Switch into the project that contains the pod you would like to access. This is necessary because the oc rsh command does not accept the -n namespace option:

    $ oc project <namespace>

  2. Start a remote shell into a pod:

    $ oc rsh <pod_name>  (1)

    1. If a pod has multiple containers, oc rsh defaults to the first container unless -c <container_name> is specified.

  3. Start a remote shell into a specific container within a pod:

    $ oc rsh -c <container_name> pod/<pod_name>

  4. Create a port forwarding session to a port on a pod:

    $ oc port-forward <pod_name> <host_port>:<pod_port>  (1)

    1. Enter Ctrl+C to cancel the port forwarding session.
