To allow only a specific IP or network to access the containers, insert a Restrict connections to the Docker hostīy default, all external source IPs are allowed to connect to the Docker host. When a port gets exposed through Docker, you must add these rules to theĭOCKER-USER chain. If you expose a port through Docker, this port gets exposed no matter what Iptables-based firewall - are evaluated after these chains. Rules added to the FORWARD chain - either manually, or by another These rules are appliedīefore any rules Docker creates automatically. If you need to add rules which load beforeĭocker’s rules, add them to the DOCKER-USER chain. Add iptables policies before Docker’s rulesĭocker installs two custom iptables chains named DOCKER-USER and DOCKER,Īnd it ensures that incoming packets are always checked by these two chainsĪll of Docker’s iptables rules are added to the DOCKER chain.
