## Docker Networking design as of Docker v1.6
|
|
|
|
Prior to libnetwork, Docker Networking was handled in both Docker Engine and libcontainer.
|
|
Docker Engine makes use of the Bridge Driver to provide single-host networking solution with the help of linux bridge and IPTables.
|
|
Docker Engine provides simple configurations such as `--link`, `--expose`,... to enable container connectivity within the same host by abstracting away networking configuration completely from the Containers.
|
|
For external connectivity, it relied upon NAT & Port-mapping
|
|
|
|
Docker Engine was responsible for providing the configuration for the container's networking stack.
|
|
|
|
Libcontainer would then use this information to create the necessary networking devices and move them in to a network namespace.
|
|
This namespace would then be used when the container is started.
