# bootstrap.sh — Install ArgoCD via Helm and apply the root App-of-Apps
# Run this once inside the VM after `vagrant up`.
#
# Usage:
#   cd /vagrant
#   ./scripts/bootstrap.sh
#
# What it does:
#   1. Creates the argocd namespace
#   2. Installs ArgoCD via Helm using manifests/argocd/values.yaml
#   3. Waits for ArgoCD server to be ready
#   4. Applies apps/root.yaml  (App-of-Apps entry point)
#   5. Prints the initial admin password and a port-forward hint
