Is it possible to assign a static public ip to a Docker Container?

Question

I have been trying to assign one of my five public ip\'s to my docker container. It seems like this should be possible because of the nature of docker and its uses. I found this

Answer 1

Docker 1.10 will allow you to specify a static IP-address for a container for each network it's connected to.

(Note that, for backward compatibility, this feature is only supported for custom networks, and only if a subnet is specified)

For example;

docker network create -d bridge --subnet 172.25.0.0/16 mynet

docker run -d --net=mynet --ip=172.25.3.3 nginx

For more information see the documentation pull request

Answer 2

The only way I know of to have a docker container use a static ip is using pipework.

Assuming you mean acquiring a DHCP lease and showing up on your router page -- Nothing comes to mind with docker. I don't think that is "the docker way". It's pretty simple with nspawn if you are using a systemd based distro, FWIW.

Possible Solution but I can't test it right now. Please let me know if this is incorrect.

Make virtual network interface with macvlan:

See https://superuser.com/questions/175475/ip-address-alias-assigned-by-dhcp

commands:

ip link add dev macvlan0 link eth0 type macvlan #macvlan0 being the name of the v-card (lol)

Connect container to virtual network interface with pipework:

see https://github.com/jpetazzo/pipework/#connect-a-container-to-a-local-physical-interface

commands:

pipework macvlan0 $($containerid) dhcp
