So let’s spin up an Ubuntu container with the following command − You can now attach the new network when launching the container. Sudo docker network create –-driver bridge new_nw The command will output the long ID for the new network. Name − This is the name given to the network. This can be done with the following command − Syntaxĭocker network create –-driver drivername nameĭrivername − This is the name used for the network driver. The goal of libnetwork is to deliver a robust Container Network Model that provides a consistent programming interface and the required network abstractions for applications. You can list the network by running the following command: sudo docker network ls. In this example, we'll create a network called net1 and run an ubuntu container inside it: sudo docker network create net1. One can create a network in Docker before launching containers. Libnetwork provides a native Go implementation for connecting containers. You can create a new network with docker network create command. Now if we inspect our network name via the following command, you will now see that the container is attached to the bridge. Sudo docker run –it ubuntu:latest /bin/bash Let’s spin up an Ubuntu container with the following command −
#Docker network container driver#

Now let’s run a container and see what happens when we inspect the network again. After the docker installation you have 3 networks by default. The output of the above command is shown below − The command will output all the details about the network. Networkname − This is the name of the network you need to inspect. If you want to see more details on the network associated with Docker, you can use the Docker network inspect command. The output of the above command is shown below Inspecting a Docker network The command should pull the hello-world container from Docker Hub (the Docker registry containing the ready-to-use container images), spin it up and have it generate some output to your screen. The command will output all the networks on the Docker Host. This command can be used to list all the networks associated with Docker on the host. Now let’s look at some commands associated with networking in Docker. This is a bridge between the Docker Host and the Linux Host.

Check if the container instance has an IP address. If not, you will next to fix that first before moving on to the next step. This adapter is created when Docker is installed on the Docker Host. Check if the Docker network interface is up and running (with a command like ip or ifconfig). If you do an ifconfig on the Docker Host, you will see the Docker Ethernet adapter. Docker takes care of the networking aspects so that the containers can communicate with other containers and also with the Docker Host.
