- Create a new repo for managing argo files.
- Create an argocd application architecture to deploy k8s manifest files for two clusters. (use application, applicationsets, projects) (at-least 8-10 sample apps should be deployed)
- Deploy a kustomize application to 2 different cluster as prod and stage with one base.
- All the sync should be automated.
- Add git webhook which can trigger the sync as soon as any changes are pushed to repo.
- Should get flock msg for each step of sync Pre, post etc.

- project.yaml consists of clusters access
- root.yaml is applied
- envs - production and staging application are applied
- It then calls the kustomize files present in overlays folder
- Which then calls the kustomzation.yaml present in base folder
