Unable build docker-compose file with advanced network configuration

[mik-laj]

Hello,

I wanted to build images with docker buildx bake command, but my file has the following network configuration.

networks:
  example.com:
    name: example.com
    driver: bridge
    ipam:
      config:
        - subnet: 10.5.0.0/24
          ip_range: 10.5.0.0/24
          gateway: 10.5.0.254

but I got the following error:

error: networks.example.com.ipam.config.0 Additional property gateway is not allowed
Error: Process completed with exit code 1.

Docker-Buildx 0.5.1

Is this a valid compose file? Seems to fail in the parser that is not part of build itself.

This file is supported by docker-conoose, so i think, it is valid file. Whats else should i check?
See: https://github.com/mik-laj/presto-kerberos-docker/blob/master/docker-compose.yml

Thanks for raising this @mik-laj. I think this is because of differences in how we parse Compose files in docker-compose vs buildx. I've created a ticket to track updating the parser in buildx: #634.
