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'

For this example, I have a very simple Node.js applications that increments a counter stored on Redis. I want to run Redis and the node application independently as I want to have the ability to scale the node application depending on the load. To start off, I have 3 instances of the node server running the application. I have an Nginx server in front of node for load balancing the node instances.

Let’s now talk in terms of containers, specifically Docker containers. Simple; 1 container for each service/process!

• 1 Redis container
• 3 Node containers
• 1 Nginx container So, the overall picture looks something like this:

version: "3"

services:

  web:
    image: nginx:alpine
    ports:
        - "8080:80"
    volumes:
        - ./site.conf:/etc/nginx/conf.d/site.conf
