# bootstrap.sh — Installeer ArgoCD via Helm en genereer de root App-of-Apps
|
|
# Eénmalig uitvoeren in de VM na `vagrant up`.
|
|
#
|
|
# Gebruik:
|
|
# cd /vagrant
|
|
# ./scripts/bootstrap.sh
|
|
#
|
|
# Wat het doet:
|
|
# 1. Detecteert de URL van jouw fork op basis van de git remote
|
|
# 2. Maakt de argocd namespace aan
|
|
# 3. Installeert ArgoCD via Helm (manifests/argocd/values.yaml)
|
|
# 4. Wacht tot ArgoCD klaar is
|
|
# 5. Past apps/project.yaml toe
|
|
# 6. Genereert apps/root.yaml met jouw fork-URL en past het toe
|
|
# 7. Print het admin-wachtwoord en een port-forward hint
