What is console?

The console provides the user interface for Red Hat Advanced Cluster Management (ACM) for Kubernetes and Red Hat MultiCluster Engine (MCE).

Go to the Contributing guide to learn how to get involved.

Prerequisites

• Node.js 14
• NPM 6

Running

1. Clone repository

2. Install dependencies

   npm ci
   

3. Setup environment

   You need:

   • to be connected to a OpenShift 4.x.x cluster
   • to have Advanced Cluster Management installed on the cluster

   npm run setup
   

   This will create a .env file in the backend directory containing environment variables.

4. Start the development services

   npm start
   

   This will start the frontend and the backend in parallel. (It may take up to 30 seconds for the UI to appear)

Running as an OpenShift console plugin-in

See Dynamic Plugins - Development

Architecture

See ARCHITECTURE.md

Chrome

To develop with self signed certificates goto chrome://flags/and enable

• Allow invalid certificates for resources loaded from localhost.
• Insecure origins treated as secure.
  • http://localhost

Authentication

Frontend has a cookie acm-access-token-cookie that contains the user's token.

If the backend responds with a 401 Unauthorized the frontend starts an OAuth flow to authorize with the cluster.

1. Frontend redirects to the backend /login endpoint.
2. Backend redirects to the cluster /authorize endpoint.
3. Cluster OAuth redirects back to the backend /login/callback endpoint.
4. Backend redirects to the frontend and sets the acm-access-token-cookie.

Optional Features

In some cases there are development preview (Dev Preview) features or technical preview (Tech Preview) features that can optionally be enabled and used in the product. These features are enabled by updating the console-config configmap in the installation namepsace (default: open-cluster-management). The following features are available:

Single node OpenShift

Enabling this feature will allow the user to create a cluster that only contains a single control plane node. This option is only available for providers AWS, Azure, GCP, OpenStack and VMware when the OpenShift release image is version 4.8 or higher.
