If I attempt to use docker-compose up with a piped-in docker-compose file I experience a failure:
me@me-desktop:/tmp$ echo "version: '3'
services:
container1:
image: quay.io/my-org/image
container2:
image: quay.io/my-org/image
" | docker-compose -f - up
Traceback (most recent call last):

However, if I write this same configuration to a docker-compose.yml file and run docker-compose up the two containers come up just fine. Unfortunately for my test setup, I need to be able to pipe and can’t write to disk.
Was wondering if anyone has experienced this or had guidance, thanks!
