Accessing external hosts from docker container -


i trying dockerize application. have 2 servers, server1 , server2. server1 uses webservice hosted on server2. have in /etc/default/docker on server1:

docker_opts="--dns 8.8.8.8 --dns 8.8.4.4 --iptables=false"

as understand prevents docker making changes iptables, overriding ufw settings. ufw status shows this:

status: active                          action      --                         ------      ---- 22                         allow       anywhere 443                        allow       anywhere 2375/tcp                   allow       anywhere 22 (v6)                    allow       anywhere (v6) 443 (v6)                   allow       anywhere (v6) 2375/tcp (v6)              allow       anywhere (v6)

now trouble not able access server2 app runs in container on server1. if don't use --iptables=false flag can access server2. can access server2 container without having sacrifice ufw ?

if matters , both server1 , server2 on digitalocean , have private networking enabled.
