fccbd1a45a feat: Cloudflare DNS-01 ACME + Docker hardening + sysctl
Some checks failed
CI/CD / syntax-check (push) Successful in 42s
Details
CI/CD / deploy (push) Failing after 52s
Details 
Cloudflare DNS-01 ACME:
- Switch Traefik cert resolver from httpChallenge to dnsChallenge
  using Cloudflare provider (resolvers: 1.1.1.1, 1.0.0.1)
- Add CLOUDFLARE_DNS_API_TOKEN env to Traefik container
- Add CF_ZONE_ID + cloudflare_dns_api_token to all/main.yml
- Store API token in Ansible Vault

Docker daemon hardening:
- Add log-driver: json-file with max-size 10m / max-file 3
  (prevents disk fill from unbounded container logs)
- Add live-restore: true (containers survive Docker daemon restart)

Kernel hardening (sysctl):
- New roles/base/tasks/sysctl.yml via ansible.posix.sysctl
- IP spoofing protection (rp_filter)
- Disable ICMP redirects and broadcast pings
- SYN flood protection (syncookies, backlog)
- Disable IPv6 (not used)
- Restrict kernel pointers and dmesg to root
- Disable SysRq, suid core dumps

aa9706bbc4 feat: comprehensive security hardening
Some checks failed
CI/CD / syntax-check (push) Successful in 43s
Details
CI/CD / deploy (push) Failing after 59s
Details 
Traefik:
- Enable access logs → /var/log/traefik/access.log (needed for CrowdSec)
- Add global security headers middleware: HSTS, X-Frame-Options, CSP,
  nosniff, XSS filter, referrer policy, permissions policy
- Add rate limiting: default 100/s, API 30/s, admin 10/s (strict)
- Add Authelia ForwardAuth middleware for SSO integration

CrowdSec (new service):
- Analyzes Traefik access logs + auth.log in real time
- Community IP reputation blocklist (crowdsecurity/traefik + http-cve)
- Firewall bouncer: bans malicious IPs at kernel level (iptables)

Authelia (new service, auth.csrx.ru):
- 2FA/SSO portal with TOTP (Google Authenticator)
- Protects: traefik.csrx.ru, sync.csrx.ru, /god-mode/ in Plane
- Session: 12h expiry, 30m inactivity, Redis backend
- argon2id password hashing

Container security:
- Add security_opt: no-new-privileges to traefik, vaultwarden,
  forgejo, grafana, authelia

CI/CD security:
- Remove hardcoded server IP 87.249.49.32 from workflow
- Use SSH_KNOWN_HOSTS secret instead of ssh-keyscan (prevents MITM)
- Added SSH_KNOWN_HOSTS secret to Forgejo

Reliability:
- Add swap role (2GB, swappiness=10, idempotent via /etc/fstab)

- Add health checks to all services (traefik, vaultwarden, forgejo,
  plane-*, syncthing, prometheus, grafana, loki)

Code quality:
- Remove Traefik Docker labels (file provider used, labels were dead code)

Observability:
- Add AlertManager with Telegram notifications
- Add Prometheus alert rules: CPU, RAM, disk, swap, container health
- Add Loki + Promtail for centralized log aggregation
- Add Loki datasource to Grafana

6afd298730 fix: commit encrypted vault file so CI can decrypt it
All checks were successful
CI/CD / syntax-check (push) Successful in 2m0s
Details
CI/CD / deploy (push) Successful in 7m43s
Details 
vault.yml was in .gitignore so CI jobs had no vault variables.
The file is AES-256 encrypted — safe to commit to a private repo.
The password stays in ~/.vault-password-file (still gitignored).
