Introduction
The default behaviour of Docker is to assign IP addresses from its pool based on the order of containers being started. This means that you have a pool of IP addresses a bit like DNS that get randomly assigned, which in most cases is more than adequate. Sometimes you want to be clear on what container has what address and ensure everyone can talk to pass information on. The --link flag can achieve some of this but its not bi-directional, so we are going to build our own bridge. This will enable us to use a fixed IP address, avoiding the need to have linked containers. Now in Docker 1.7 they have a new experiment feature call 'SWARM' for clustering that will enable bi-directional linking, as its still in the testing phase its not something you might want in most situations.
How-To
First stop the Docker daemon and 'docker0' interface:
Then before the docker service is restarted we need to create our own bridge and set-up the configuration we need for our containers.
Make sure that the config is saved so that its applied at reboot:
Tell Docker about it and restart (Docker 1.7):
If you are using CentOS7 and docker 1.9x, then edit another configuration file:
Then reload and start docker:
Confirming new outgoing NAT masquerade is set up:
Start/Create Your Containers:
Now you can create new containers using the bridge or start existing ones. Start the containers:
Check the containers have been mapped up to the new range and bridge:
Pipework:
Now we need to install 'pipework' to manually set the system containers static address, so install pipework on the docker host:
Once this is complete you can assign the address you want to the relevant containers.
Add route entry for host to be able to connect container:
Finally a little test:
