Validation before evaluate

[lagden]

System Info

OSX 10.15.6 (19G2021)
Docker version 19.03.12, build 48a66213fe
docker-compose version 1.27.2, build 18f557f9

Installed via https://www.docker.com/products/docker-desktop

Problem

I always use .env file to setup docker-compose.yml
and now an error occurred specifically in this property: deploy.resources.reservations.cpus

The example is here:
https://github.com/lagden/compose-issue

See below what happens:

Steps

1. Run docker-compose up
2. Problem: Error caused by deploy.resources.reservations.cpus validation
3. Comment property deploy.resources.reservations.cpus in docker-compose.yml (line 15)
4. Run again docker-compose up
5. OK
