OpenShift Simple Pod Running inside an OpenShift Project

Internal

• OpenShift Operations

Overview

This is the procedure to deploy a simple pod that starts executing inside an OpenShift project and permits attaching. This could prove useful while troubleshooting network issues which need running network utilities and tests from "inside the project".

Procedure

Use the following template: https://github.com/NovaOrdis/playground/blob/master/openshift/templates/standalone-pod-template.yaml

oc process -f https://raw.githubusercontent.com/NovaOrdis/playground/master/openshift/templates/standalone-pod-template.yaml | oc create -f -

Alternatively it can be created from the following content:

apiVersion: v1
kind: Pod
metadata:
  name: standalone-pod
spec:
  containers:
  - name: oc
    image: docker.io/openshiftdemos/oc
    command: ["/bin/bash", "-c", "sleep 1000000"]
    resources:
      limits:
        memory: 128Mi

The command is optional, if missing, the image's command will be executed.

then:

oc rsh standalone-pod

When you don't need it anymore:

oc delete standalone-pod
