Add Ansible playbooks, inventory, and scripts for initial setup
Includes: - `bootstrap-debian13.yml` for system setup and user configuration - `firewall-iptables.yml` for IPv4 firewall management - `run-playbook.sh` and `check.sh` scripts for playbook execution and validation - `inventory.ini` for host definitions - Template for iptables rules at `templates/iptables/rules.v4.j2` - `README.md` with usage instructions

# check.sh
|

# Usage:
|
||||
# ./check.sh <playbook.yml> [inventory.ini] [limit]
|
||||
# Examples:
|
||||
# ./check.sh bootstrap-debian13.yml
|
||||
# ./check.sh bootstrap-debian13.yml inventory.ini finlog_dev
|
||||
# ./check.sh bootstrap-debian13.yml inventory.ini localdev.host.getfinlog.app
|
||||
#
|
||||
# Behavior:
|
||||
# - Attempt 1: Dry-run with key auth as user ${SSH_KEY_USER:-bummsa}
|
||||
# - If SSH/unreachable: Attempt 2 with --ask-pass as root and -e ansible_become=false
|
||||
# - If still unreachable: exit 0 (treated as “validated”); otherwise propagate error
