Docker compose containers quit very slowly

[nk9]

When you quit the EasyOCR example Docker compose container with Ctrl-C, you have to wait 10 seconds for the process to gracefully quit. This is because the container lacks an init process, so the EasyOCR process is itself running as PID 1.

Fortunately, it's very easy to fix with Docker compose's init setting. With that added, the process quits in 0.1s. 100x faster!

I will submit a PR for the easyocr example, since that's the one I've tested. But this is probably an issue in all the other containers as well. I'd be happy to submit a PR making the change for all of them.
