Networking

Command	Description
docker network ls	List all existing Docker networks. Displays details such as network name, ID, driver type, and scope.
docker network create <network-name>	Create a new user-defined network with the specified name. By default, it uses the bridge driver.
docker network create --driver <driver-name> <network-name>	Create a network using a specific driver (e.g., bridge, overlay, host, or none).
docker network rm <network-name>	Remove a Docker network. The network must not be in use by any containers.
docker network inspect <network-name>	Display detailed information about a network, including connected containers, IP ranges, and driver type.
docker run --network <network-name> <image>	Start a container and connect it to a specific network at runtime.
docker network connect <network-name> <container-id>	Connect an existing container to a specified network.
docker network disconnect <network-name> <container-id>	Disconnect a container from a specific network.
docker network prune	Remove all unused Docker networks. Be cautious as it deletes networks not being used by containers.
docker-compose up	Automatically creates and manages a network for the services defined in the docker-compose.yml file.
docker network create --subnet=<CIDR> <network-name>	Create a network with a custom subnet (CIDR notation).
