Creating your first user-defined bridge network

Whenever we want to connect one Docker container to another Docker container by the container name, then first we have to create a user-defined network. This is because Docker does not support automatic service discovery on the default bridge network. In this recipe, we will learn how to create our own bridge network.

How to do it…

Execute the docker network command to create a bridge network with the name as my-bridge-network, as follows:

$ docker network create my-bridge-network
 325bca66cc2ccb98fb6044b1da90ed4b6b0f29b54c4588840e259fb7b6505331

How it works…

Verify whether my-bridge-network has been created successfully by executing the following command:

$ docker network ls
 NETWORK ID NAME DRIVER
 20dc090404cb bridge bridge
 9fa39d9bb674 host host
 325bca66cc2c my-bridge-network bridge
 f36203e11372 none null

To see detailed information about my-bridge-network, run the docker network inspect command followed by the network name, as follows:

$ docker...
