My Openshift Cheatsheet

List all non openshift/kube namespaces

requires jq CLI

oc get namespaces -o json | jq '[.items[] | select((.metadata.name | startswith("openshift") | not) and (.metadata.name | startswith("kube-") | not) and .metadata.name != "default" and (true)) | .metadata.name ]'

Project Quotes, Limits and Templates

ANSI Escape Sequences

Standard escape codes are prefixed with Escape:

Ctrl-Key: ^[
Octal: \033
Unicode: \u001b
Hexadecimal: \x1B
Decimal: 27

My list of OpenShift 4 hacks

How do I list all resources in a namespace (no, really ALL of them)

adapted from https://access.redhat.com/solutions/4165791

$ oc api-resources --verbs=list --namespaced -o name | xargs  -I {} bash -c "oc get --show-kind --ignore-not-found -n openshift-storage {}"

a little faster

TLDR

Running the following script to get a nice summary of all network interface information which includes the Interface Name, IP Address, MAC Address, Link State, Link Speed, MTU, Vendor, Device ID, Driver, Total VFs, Configured VFs, and PCIe Address.

For OpenShift Single-Node deployments, you can run the following simple command:

curl -sL https://tinyurl.lab.ocp.run/ocp-netprint-sno | bash

For OpenShift Multi-Node deployments, you can run the following two commands (you need to export the var):

	#!/bin/sh
	# Adapt the two first variables to your environment
	# Requirements:
	# -the user below can connect to the IP without password (copy ssh key)
	# changes on server: ...share/crashplan/conf/my.service.xml:
	# <serviceUIConfig>
	# <serviceHost>0.0.0.0</serviceHost>
	#

	CPSSHUSER='root'
