Connecting to OpenShift Local

Red Hat OpenShift Local is the quickest way to get started building OpenShift clusters. It is designed to run on a local computer to simplify setup and testing, and to emulate the cloud development environment locally with all of the tools needed to develop container-based applications.

Prerequisites:

1. Docker Desktop
2. Red Hat OpenShift Local

Steps:

1. Use Kubernetes - Local Configuration devcontainer profile to automatically copy localhost ~/.kube/config to the devcontainer
2. Create .devcontainer/compose.yaml

# .devcontainer/compose.yaml
---
services:
  devcontainer:
    image: mcr.microsoft.com/devcontainers/base:bullseye
    volumes:
      - ../..:/workspaces:cached
    command: sleep infinity
    extra_hosts:
      - "api.crc.testing:host-gateway"    # forwards api.crc.testing to docker host gateway

3. Update .devcontainer/devcontainer.json

// .devcontainer/devcontainer.json
{
	// Comment `image` field
	// "image": "mcr.microsoft.com/devcontainers/base:bullseye",

	// Add `dockerComposeFile`, `service`, `workspaceFolder` fields
	"dockerComposeFile": "compose.yaml",
	"service": "devcontainer",
	"workspaceFolder": "/workspaces/${localWorkspaceFolderBasename}"
}
