But I was told docker fixes that with rapid reproducible rebuilds. /s

Are you the kind of person who is happy to reboot and call it fixed? Docker is for you.

Do you want to know why it failed and make changes to prevent the next failure? No docker, you are going to need to learn to document your build processes instead.

I'll leave it for the reader to decide which is the superior kind of person. Reboot monkey or tech with understanding who does proper documentation? Which way western man?
