The --iptables option only applies to the Docker daemon; it's not a per-container option. The corollary is that this isn't something you could ever set from your docker-compose.yaml file.

You would need to modify the options passed to the Docker daemon; on Red Hat systems and derivatives this means you would modify /etc/sysconfig/docker and updte the OPTIONS= line (and restart Docker). There will be a similar process for other distributions.

On Ubuntu/Debian systems, you edit


    /etc/default/docker

so that docker_opts is uncommented and contains the iptables addition:


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

So if someone is trying to use this


    --iptables=false

setting so that they can manually control their own firewall (e.g., UFW), then they should clear the iptable rules appropriately after enabling this docker setting (and restarting docker/server). – Dolan Antenucci Apr 8, 2017 at 4:05

Could check out saltstack if you're looking for this level of automation. They have a dockerng state which allows you to specify options.
