Question

In my docker-compose.yml I have external: false but docker-compose config gives me external: true.

What is the reason for this change of value? My assumption was that this command just validates the file and performs only cosmetic changes.

How to reproduce

$> cat docker-compose.yml
version: '3.4'

volumes:
      test-volume:
          name: test-name
          external: false

services:
    test-service:
        image: test-image

$> docker-compose -f docker-compose.yml config
services:
  test-service:
    image: test-image
version: '3.4'
volumes:
  test-volume:
    external: true
    name: test-name

$> docker-compose --version
docker-compose version 1.21.2, build a133471

Update:

@Nicola proved that this is a bug: https://github.com/docker/compose/issues/6037

I verified this behaviour and what you described, in my opinion, deserves an issue in https://github.com/docker/compose/issues
