Summary

This provides an application deployer for ArgoCD using RHACM.

Prerequisite

• 1+ managed-clusters
• ArgoCD installed in the cluster (RH GitOps Operator) you want to deploy pacman app

How to use the repo

• Clone the repo
• Log in an OpenShift cluster
• Execute this command from inside the folder argo-acm oc apply -k acm-resources

How to add a new app

• Copy the application file pacman-app.yaml
• Change the file's name
• Inside the new file add all the info regarding the new app (Argo project, git repo, etc...)
• In the namespace.yaml file add the namespace definition in yaml that you want to use for deploying your app and add the next label: "argocd.argoproj.io/managed-by: openshift-gitops" if you do not add this label you'll get a sync error on ArgoCD and the app won't be deployed.
