This flag interacts with the IP forwarding setting on your host system’s kernel

iptables

Enable Docker’s addition of iptables rules

ip_masq

Enable IP masquerading for bridge’s IP range.

socket_bind

Which local unix socket to bind the docker service to.

Which local unix socket to bind the docker service to.

root_dir

Specify a non-standard root directory for docker.

extra_parameters

Plain additional parameters to pass to the docker daemon

shell_values

Array of shell values to pass into init script config files
