Networking and bridging in docker containers

[ashay-maheshwari]

Docker containers are connected with a automatically created bridge called docker0. All containers are internally connected with docker0 bridge as in private network.

We need to expose those containers, so that they can be accessed from other machines in the network. This need exploration of networking and bridging option in docker.

We can create our own bridge and we can use that bridge for our containers.
I created the bridge using
docker network create -d bridge --subnet x.x.x.x/x --gateway x.x.x.x -o <options> <bridge-name>
after that we can create containers using this bridge as follows
docker run/create -itd --net <bridge-name> --name <name-of-the-container> busybox
