platform management (gitops hub and workers template)

TODO

Initialize

This is the process for initializing the gitops loop between Red Hat OpenShift GitOps (ArgoCD) Applications and Red Hat Advanced Cluster Management for Kubernetes (Open Cluster Management) Policies for a target hub1 cluster.

Prerequisites

1. Deploy an unmodified Red Hat OpenShift Container Platform cluster
2. copy this template repositories to git server of your choice
   • https://github.com/itewk/gitops-hub-and-workers-template-platform-management
   • https://github.com/itewk/gitops-hub-and-workers-template-capabilities
   • https://github.com/itewk/gitops-hub-and-workers-template-tenants
3. TODO - how to update all the URLs
4. install required tools
   • helm
   • kustomize
   • ansible
   • kustomize plugin: open-cluster-management-io/PolicyGenerator

Kickoff self healing loop gitops loop of awesomeness

1. Log into cli of target hub cluster
2. Initialize the reconciliation loop

Colors

An attempt has been made where color is used in console customizations to be color blind safe based on Paul Tol's Notes: Colour schemes and templates: Sequential Colour Schemes: Figure 18a.

Status

Current status of this repository

• Initialization is tested as working against Red Hat OpenShift Container Platform cluster 4.16.12
• Gitops-ify adding managed clusters to RHACM
• Implement sample "managed workload cluster"
• Update kuztomizations to point at git links rather then relative links to support structural promotions
• Document repo description / purpose
• Document repo architecture
