A repository for deploying OpenShift clusters with Red Hat Advanced Cluster Management for Kubernetes and OpenShift GitOps.
All cluster lifecycle is managed by Argo CD, including the Argo configuration itself.
until oc apply -k https://github.com/redhat-partner-solutions/vse-carslab-hub/bootstrap/overlays/default; do sleep 3; done| # | Directory Name | Description |
|---|---|---|
| 1. | bootstrap |
This is where openshift-gitops configurations is stored. These are the items that get the cluster/automation started. base is where are the "common" YAML would live and overlays are configurations specific to the cluster. |
| 2. | components |
This is where specific components for the GitOps Controller lives (in this case Argo CD).applicationsets is where all the ApplicationSets YAMLs live.Other things that can live here are RBAC, Git repo, and other Argo CD specific configurations (each in their repsective directories). |
| 3. | core |
This is where YAML for the core functionality of the cluster live. Here is where the Kubernetes administrator will put things that is necessary for the functionality of the cluster. Under gitops-controller is where you are using Argo CD to manage itself. The kustomization.yaml file uses bootstrap/overlays/default in it's bases configuration. This core directory gets deployed as an applicationset which can be found under components/applicationsets/core-components-appset.yaml.To add a new "core functionality" workload, one needs to add a directory with some yaml in the core directory. See the advanced-cluster-management directory as an example. |
| 4. | clusters |
This is where the new clusters configuration is stored. To add a new Managed cluster, one needs to add a directory with some yaml in the overlays directory. See the blazer directory as an example. |
| 5. | add-workers |
This is where the configuration to add day2 worker nodes is stored. To add a day2 worker node to an OpenShift cluster, add the yamls to add-workers\<node-name>\overlay\<cluster-name>. See the add-workers\du3-ldc1\overlay\volante for an example. |
Note This repository is using sealed secrets for secrets management.
If you would like to use another secrets management solution, please change the SealedSecret manifests accordingly.
