CiaB with docker-compose 2.0.1: key cannot contain a space

This Bug Report affects these Traffic Control components:

• CDN in a Box

Current behavior:

When trying to build or run CDN in a Box using docker-compose version 2.0.1, I get this error with exit code 15:

key cannot contain a space

Expected behavior:

CDB in a Box should not fail to build or run due to issues with spaces in keys

Steps to reproduce:

[user@computer cdn-in-a-box]$ git rev-parse HEAD

[user@computer cdn-in-a-box]$ docker-compose version
Docker Compose version 2.0.1
[user@computer cdn-in-a-box]$ docker-compose build
key cannot contain a space
