In Docker, there are several types of networks you can create, each serving different use cases:
-
Bridge Network:
- The default network type.
- Allows containers to communicate with each other on the same host while isolating them from other networks.
-
Host Network:
- Removes network isolation between the container and the Docker host.
- The container shares the host's network stack and can directly access the host's network interfaces.
-
Overlay Network:
- Enables communication between containers across multiple Docker hosts.
- Useful for multi-host setups, such as in Docker Swarm or Kubernetes.
-
Macvlan Network:
- Allows you to assign a MAC address to a container, making it appear as a physical device on the network.
- Useful for scenarios where you need containers to be directly accessible on the local network.
-
None Network:
- Disables all networking for the container.
- Useful for containers that do not need network access.
You can specify the network type when creating a network using the --driver option with the docker network create command.
