Docker Kata 5: Docker Networking
Learn how to list containers, ping between containers, create a user-defined network, and run containers on the network.
Docker uses software-defined networking to provide containers with a means to connect to a network. Software-defined networking uses software, instead of physical devices such as hardware load balancers and routers, to define a TCP/IP network. The Docker Engine provides a set of predefined networks on which to run containers. Administrators can also define custom networks to support a wide variety of network configurations. This kata will demonstrate how to work with Docker networks.
Step 1: List all networks
First,
The command to list all Docker networks is given below.
docker network ls
The output will be something like:
Commands
Parameter | Description |
| This is the parent command. |
| This lists all the networks when used with the |
The docker network ls command lists all the defined Docker networks. Docker adds three networks on installation: bridge, host, and none.
The bridge network is the default network on which all containers are run.
The host network is the host’s network adapter. Containers on this network share the host’s network ...
