Monitor Cloudflare IP range for changes and auto-update configs for various services.
⚠️ WARNING: This container is no longer in active development. Consider using alternatives.
Cloudflare IP range does not change too frequently. Nevertheless, Cloudflare recommends monitoring that list on a regular basis. This container monitors Cloudflare IP range for changes and auto-updates configuration of several services. Currently, these services are supported:
- nginx (set_real_ip_from, real_ip_header directives)
- nftables (tcp dport https ip saddr CLOUDFLARE_IP counter accept directive)
- iptables (both ipv4 and ipv6)
Here is a basic snippet to help you get started creating a container.
docker run -dit --restart unless-stopped \
--name cloudflare-ips \
-v </path/to/config/dir>:/opt/cloudflare-ips \
-e CF_INTERVAL=300 \
-e PUID=1000 \
-e PGID=1000 \
