What is the default docker network?

When you start Docker, a default bridge network (also called bridge ) is created automatically, and newly-started containers connect to it unless otherwise specified. You can also create user-defined custom bridge networks. User-defined bridge networks are superior to the default bridge network.

How do I find my docker network?

Does a Docker container have its own IP address?

IP address and hostname By default, the container is assigned an IP address for every Docker network it connects to. The IP address is assigned from the pool assigned to the network, so the Docker daemon effectively acts as a DHCP server for each container. Each network also has a default subnet mask and gateway.

How does Docker network work?

Docker (and probably any container technology) uses linux network namespaces to isolate container network from host network . When Docker creates and runs a container; it creates a separate network namespace (container network) and puts the container into it. Then, Docker connects the new container network to linux bridge docker0 using a veth pair.

What is Docker network interface?

The interface docker 0 is not ordinary. The docker 0 is an Ethernet bridge, virtual and is used for forwarding network packets automatically through any kind of network interfaces which are attached to docker 0. This enables the communication between Docker containers within its peer groups and also with host system.

What is Docker bridge network?
