Kubernetes/OpenShift GitOps - Manage the capabilities or your cluster. The Initialization.
This section contains the initialization part. It installs OpenShift GitOps with Argo CD. Newer version does not contains Tekton/OpenShift Pipelines anymore. Separat installation is needed and covered with the here provided configuration.
The first version of this solution used the ArgoCD App of Apps pattern to bootstrap and manage the dynamic list of applications.
The latest version use the new feature base on ArgoCD ApplicationSet. ApplicationSet generates Application resources using configuration from a static list or git repository.

Install as follow - execute the script twice with a short wait period between both executions. This is currently the simplest solution to install the base operator (here: OpenShift GitOps), wait that the operator is done before apply the ArgoCD configuration. An alternative could be Ansible or similar - but this would increase the technology entry barrier.

Wait for that ArgoCD to be installed. The installation process also deploys an ArgoCD Application which links the Cluster Config. Depends on the Cluster-Config you will have no or the first capabilities as ArgoCD Applications configured and initialized.
in preparation
This is the foundation for the GitOps solution to manage a Kubernetes/OpenShift cluster using Argo CD.
