Itself, and requires a restart of Docker. In addition, configuring the default bridge network happens outside of Docker If your containers use the default bridge network, you can configure it, butДЄll the containers use the same settings, such as MTU and iptables rules. To remove a container from the defaultД«ridge network, you need to stop the container and recreate it with differentД®ach user-defined network creates a configurable bridge. Using a user-defined network provides a scoped network in which only containers attached to that network are able to communicate.Д¬ontainers can be attached and detached from user-defined networks on the fly.Дuring a containerвЂ™s lifetime, you can connect or disconnect it from This can be a risk, as unrelated stacks/services/containers are then able to communicate. User-defined bridges provide better isolation.ДЄll containers without a -network specified, are attached to the default bridge network. Gets complex with more than two containers which need to communicate.ДЄlternatively, you can manipulate the /etc/hosts files within the containers,Д«ut this creates problems that are difficult to debug. These links need to be created in both directions, so you can see this To manually create links between the containers (using the legacy -linkДЇlag). If you run the same application stack on the default bridge network, you need Your containers web and db, the web container can connect to the db containerДЄt db, no matter which Docker host the application stack is running on. Imagine an application with a web front-end and a database back-end. On a user-defined bridge network, containers can resolve User-defined bridges provide automatic DNS resolution between containers.Д¬ontainers on the default bridge network can only access each other by IPДЄddresses, unless you use the -link option, which isД¬onsidered legacy. Differences between user-defined bridges and the default bridge User-defined bridge networks are superior to the default bridge You can also create user-defined custom bridge

When you start Docker, a default bridge network (alsoД¬alled bridge) is created automatically, and newly-started containers connect

TheДocker bridge driver automatically installs rules in the host machine so thatД¬ontainers on different bridge networks cannot communicate directly with eachД«ridge networks apply to containers running on the same Docker daemon host.ДЇor communication among containers running on different Docker daemon hosts, youД¬an either manage routing at the OS level, or you can use an Isolation from containers which are not connected to that bridge network.

In terms of Docker, a bridge network uses a software bridge which allowsД¬ontainers connected to the same bridge network to communicate, while providing A bridge can be a hardwareДevice or a software device running within a host machineвЂ™s kernel.

Which forwards traffic between network segments. In terms of networking, a bridge network is a Link Layer device
