# hellodevops

Projekt treningowy OKD/ArgoCD/GitLab/Jenkins.

## Struktura repo
- `app/`    – kod aplikacji (1 plik Java) + Dockerfile
- `gitops/` – GitOps: Helm + Kustomize + Argo CD (dev/bis/prod)

## Środowiska (OpenShift namespaces)
- `hellodevops-dev`
- `hellodevops-bis`
- `hellodevops-prod`

## GitOps flow (skrót)
- Jenkins odpala build w OKD (BuildConfig), OKD publikuje obraz do internal registry
- Jenkins pobiera pullspec (digest) i aktualizuje `gitops/kustomize/overlays/*/values-*.yaml`
- Argo CD:
  - `dev` i `bis`: auto-sync
  - `prod`: manual sync (commit jest, ale wdrożenie ręcznie w Argo)
