[kwlug-disc] going slightly script in script in dockerfile

[Mikalai Birukou]

I've asked about your opinion about use of `node -e <js-commands>` in a

Let me ask your opinion about use of `bash -c <bash-commands>` in 
dockerfile's ENTRYPOINT directive.

Is this go slightly too far? https://www.youtube.com/watch?v=Od6hY_50Dh0
