Specify the favorite IP of the host network with docker-compose and start it

Thing you want to do

docker-compose up Specify any IP address of the host network and start it up.

What does it mean?

Basics are unnecessary and I think the correct way is to use service discovery such as nginx-proxy or treafik. However, I think there are rare use cases like ↓ that can not be done with that, so I will leave it as a memorandum.

--When you want to fix the IP such as in-house infrastructure --When you want to shift the IP and avoid port booking --8080,8081,8082 ... I want to see which port is free so that it will not be a battle

How to do

Use the macvlan network driver.

docker-compose.yml

version: "3.8"

services:
  web01:
    image: nginx
    networks:
      macvlan:
        ipv4_address: 192.168.1.10
    # ports
    #  - "80:80"I want to see docker's host network, the port is fully open with the specified IP, so the basics are unnecessary
    ...etc

  web01:
    image: nginx
    networks:
      macvlan:
        ipv4_address: 192.168.1.20
    # ports
    #  - "80:80"Port does not book because IP is different
    ...etc

...etc

networks:
  macvlan:
    driver: macvlan
    driver_opts:
      parent: eno1 #Specify the network interface of the terminal
    ipam:
      config:
        - subnet: 192.168.1.0/24
          gateway: 192.168.1.1
