feat: Cloudflare DNS-01 ACME + Docker hardening + sysctl
CI/CD / syntax-check (push) Successful in 42s
CI/CD / deploy (push) Failing after 52s
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

feat: major infrastructure improvements
CI/CD / deploy (push) Has been cancelled
CI/CD / syntax-check (push) Successful in 1m7s
Reliability:
- Add swap role (2GB, swappiness=10, idempotent via /etc/fstab)
- Add mem_limit to plane-worker (512m) and plane-beat (256m)
- 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)
- Add comment explaining file provider architecture
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
- Enable Traefik /ping endpoint for health checks
Backups:
- Add backup role: pg_dump for forgejo + plane DBs, tar for
vaultwarden and forgejo data
- 7-day retention, daily cron at 03:00
- Backup script at /usr/local/bin/backup-services
