Docker Network Types

Bridge Network (Default)

Used for communication between containers on the same host.
Created automatically when running containers.
Manually create: docker network create my_bridge_network
Docker Compose:

#yaml
networks:
  my_bridge_network:
    driver: bridge

Host Network

Containers share the host’s network namespace (no isolation).
Manually create: docker network create -d host my_host_network
Docker Compose:

# yaml
networks:
  my_host_network:
    driver: host

Overlay Network

Used in Swarm mode for multi-host communication.
Manually create: docker network create -d overlay my_overlay_network
Docker Compose:

Macvlan Network

Assigns containers unique IPs on the local network.
Manually create: docker network create -d macvlan --subnet=192.168.1.0/24 --gateway=192.168.1.1 -o parent=eth0 my_macvlan_network
Docker Compose:

None Network

Completely isolates the container (no networking).
Manually create: docker network create -d none my_none_network
Docker Compose:

Specify static ip address

Commands

docker network ls
docker network inspect $name
docker network connect $network $container: connect $container to $network
docker network create -d macvlan -o parent=enp86s0.4 vlan4_net: create network
docker network create -d macvlan --subnet=192.168.4.0/24 --gateway=192.168.4.1 -o parent=enp86s0.4 vlan4_net
