How can I list all resources and custom resources in OpenShift

List all CRDs with CR name and Scope

oc get crd -o=custom-columns=NAME:.metadata.name,CR_NAME:.spec.names.singular,SCOPE:.spec.scope

List every single custom resources in the cluster

oc get $(oc get crd -o=custom-columns=CR_NAME:.spec.names.singular --no-headers | awk '{printf "%s%s",sep,$0; sep=","}') --ignore-not-found --all-namespaces -o=custom-columns=KIND:.kind,NAME:.metadata.name,NAMESPACE:.metadata.namespace

List every single resource in the cluster (custom and non-custom)

oc get $(oc api-resources --verbs=list -o name | awk '{printf "%s%s",sep,$0;sep=","}') --ignore-not-found --all-namespaces -o=custom-columns=KIND:.kind,NAME:.metadata.name,NAMESPACE:.metadata.namespace --sort-by='metadata.namespace'

Introduction

The objective of these instructions is to create a complete Arm64 OS (Userland and Kernel) using Debian Debootstrap and RPI-Update for use on the Raspberry Pi 3 and 4.

Prerequisites:

• An existing Debian/Raspbian system (any architecture will do)
• An empty SD card formatted as per a standard Raspbian installation mounted to /mnt/sd on the build system
  • 1st Partition 0-256MB = FAT32 (Mount to /mnt/sd/boot)
  • 2nd Partition 256MB+ = EXT4 (Mount to /mnt/sd)

Set-up basic Debian system
