ASXP.IO Ansible

Post-cloud-init configuration for asxpio servers.

Playbooks

setup-servers.yaml

Post-deployment verification (cloud-init handles base setup).

ansible-playbook playbooks/setup-servers.yaml

wireguard.yaml

Deploy WireGuard VPN server on asxpio-ops (10.20.0.10).

# Initial deployment
ansible-playbook playbooks/wireguard.yaml

# Add new clients to inventory/host_vars/asxpio-ops.yaml, then re-run
ansible-playbook playbooks/wireguard.yaml

Client configs fetched to ./wireguard-configs/asxpio-ops/

wireguard-client.yaml

Deploy WireGuard client configs to servers.

ansible-playbook playbooks/wireguard-client.yaml

Deploys asxpio-services.conf (10.20.0.20) to asxpio-services server.

ssh-harden.yaml

Harden SSH configuration with network restrictions and strong cryptography.

ansible-playbook playbooks/ssh-harden.yaml

Security measures:

• Shell access (asxpi/deploy/root): Only from VPC (10.10.0.0/20) or WireGuard (10.20.0.0/24)
• Forgejo git user: Public access on asxpio-ops for git operations (ssh://forgejo@git.asxp.io/...)
• Strong crypto: ChaCha20-Poly1305, AES-GCM, RSA-SHA2, Ed25519
• iptables: SSH blocked on asxpio-services except from trusted networks
• Enhanced sshd_config: MaxAuthTries 3, MaxSessions 5, no X11 forwarding

Access after hardening:

• Admin access: Connect via WireGuard VPN first, then SSH
• Git operations: Public access to asxpio-ops (Forgejo handles authentication)
• Internal VPC: Servers can SSH to each other via 10.10.0.0/20

deploy-traefik.yaml

Deploy Traefik reverse proxy with Let's Encrypt on asxpio-ops.

ansible-playbook playbooks/deploy-traefik.yaml

Features:

• Automatic HTTPS with Let's Encrypt (HTTP challenge)
• Dashboard accessible only via WireGuard (http://10.20.0.10:8080)
• Shared Docker network for service discovery
• Certificates stored in /opt/traefik/letsencrypt/
• Logs in /opt/traefik/logs/

deploy-forgejo.yaml

Deploy fresh Forgejo Git server on asxpio-ops (no data migration).

ansible-playbook playbooks/deploy-forgejo.yaml

Configuration:

• Forgejo 12.x with SQLite database
• HTTP: port 3000 (internal), exposed via Traefik at git.asxp.io
• SSH: port 2222 (external) → 22 (container)
• Actions enabled with 365-day artifact retention
• LFS enabled, OAuth2 enabled
• Data stored in /opt/forgejo/data/

Important: Configure secrets in inventory/host_vars/asxpio-ops.yaml:

forgejo_secret_key: "YOUR-SECRET-KEY"
forgejo_internal_token: "YOUR-INTERNAL-TOKEN"
forgejo_jwt_secret: "YOUR-JWT-SECRET"
forgejo_lfs_jwt_secret: "YOUR-LFS-JWT-SECRET"
letsencrypt_email: "admin@asxp.io"

deploy-forgejo-runner.yaml

Deploy Forgejo Runner on asxpio-services for CI/CD.

ansible-playbook playbooks/deploy-forgejo-runner.yaml

Configuration:

• Forgejo Runner 11.x with Docker execution
• 14 pre-configured labels (ubuntu, debian, arch, node, python, nginx, alpine)
• Connects to Forgejo via VPC (http://10.10.0.10:3000)
• Requires manual registration after deployment

Post-deployment registration:

# 1. Get registration token from Forgejo:
#    Site Administration > Actions > Runners > Generate Token

# 2. Register the runner:
ssh asxpio-services
docker exec -it forgejo-runner forgejo-runner register --no-interactive \
  --token YOUR_REGISTRATION_TOKEN \
  --name runner-asxpio-services \
  --instance http://10.10.0.10:3000

# 3. Restart runner:
cd /opt/forgejo-runner && docker compose restart

backup-forgejo.yaml

Backup Forgejo from old server (10.0.0.1).

ansible-playbook playbooks/backup-forgejo.yaml

What it does:

1. Stops Forgejo service temporarily
2. Creates dump: forgejo dump -c /etc/forgejo/app.ini
3. Creates additional archive of:
   • Database: /srv/gitea/gitea.db
   • Repositories: /srv/gitea/data/
   • SSH keys: /var/lib/forgejo/.ssh/
   • Runner registration: /var/lib/forgejo-runner/.runner
4. Fetches backups to local machine: /tmp/forgejo-backups/
5. Restarts Forgejo service

Backup includes: Database, repositories (~513MB), configuration, SSH keys, runner registration.

restore-forgejo.yaml

Restore Forgejo backup to new server (10.20.0.10 via WireGuard).

ansible-playbook playbooks/restore-forgejo.yaml

Prerequisites:

• Traefik deployed and running
• Forgejo deployed (fresh instance)
• Backup files in /tmp/forgejo-backups/

What it does:

1. Stops Forgejo container
2. Extracts dump backup to /opt/forgejo/
3. Restores database, repositories, SSH keys
4. Sets correct ownership (UID 1000)
5. Starts Forgejo container
6. Waits for health check

Post-restore verification:

# Test web interface
curl -I https://git.asxp.io

# Test git clone
git clone https://git.asxp.io/asxpi/infrastructure.git

# Test SSH access
git clone git@git.asxp.io:asxpi/infrastructure.git

Deployment Order

Phase 1: Infrastructure (Prerequisites)

# 1. Deploy VPN
ansible-playbook playbooks/wireguard.yaml
