Explanation

Macvlan is one of the features of Linux Kernel, and it is also a network solution that can be natively supported by Docker, which is configured through Macvlan for container networks and host networks Containers have the same network capabilities as hosts, and cross-node container access does not require NAT. Macvlan can be used on one of the host's network interfaces either Multiple virtual network interfaces are configured on the VLAN sub-interfaces for use by the container, and these virtual network interfaces have independent MAC addresses and IP addresses. ?Macvlan requires a physical NIC to support promiscuous mode, and the container gateway is on the physical switch, which has the disadvantage of not having IPAM (IP Address Mangement) and container IP Rely on manual configuration and management.
