여기 지침에 따르면 Docker 버전 20.10.6-ce, 빌드 8728dd246c3a를 사용하는 openSUSE Tumbleweed에서 제대로 작동합니다.
https://github.com/mirumee/saleor-platform#how-to-run-it
그러나 Docker 버전 19.03.15, 빌드 99e3ed89195c가 포함된 openSUSE Leap 15.3에서는 migrate명령(마지막 명령)에서 오류가 발생합니다.
$ git clone https://github.com/mirumee/saleor-platform.git --recursive --jobs 3
$ cd saleor-platform
$ docker-compose build
$ docker-compose run --rm api python3 manage.py migrate
