# Playbook: app/configure_app.yml
# Purpose: Configure OS + app runtime on app project guests created via provision_vms.yml
# Targets: app_all or per-project group created dynamically
# Tags: app, configure
#
# Usage:
# - Run one project: ansible-playbook -i inventories/production playbooks/app/site.yml -e app_project=projectA
# - Run all projects: ansible-playbook -i inventories/production playbooks/app/site.yml
