When trying to create a network in docker-compose.yml :

version: "3.5"
networks:
  frontend:
    name: custom_frontend
    driver: custom-driver-1

I faced to following issue:

ERROR: The Compose file './docker-compose.yml' is invalid because:
networks.frontend value Additional properties are not allowed ('name' was unexpected)

I was using Docker-compose version 1.17.1

This happened , because  docker-compose release, I was using (1.17.1) is not support version 3.5 (mentionned in docker-compose Yml file).
1.17.1 only supports up to 3.4:

How to fix it ?

You can run the following commands to upgrade docker-compose to a newer/latest version, (for example 1.28.5) :

curl -L https://github.com/docker/compose/releases/download/1.28.5/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

(The commands were copied from the releases page)

After upgrade, you can run docker-compose -f <your-compose-file> config to check whether the compose file is valid. If your compose file is valid it’ll just print it out.
