• Use production docker images for cypress tests. As one of our contributors pointed out: It is bad practice to end-to-end test sth. else than the actual production images.
• Have a dedicated docker-compose.build-and-test.yml to test backend integration tests. The backend needs a database when doing integration tests. So there is no way around using docker-compose. But we could use production stage when we do cypress tests.
• Remove a couple of unused ports and DRY docker-compose.override.yml
• Build and tag all images first and then run docker-compose .. up - I hope this will avoid rebuilding the image.
• Reduce docker image size
