In my experience so far, containers are only really a bother if you're already doing things wrong and it's exposing practices that may be convenient in the short term but will bite you in the long term. I know in previous jobs the things that were obstacles to containerization were essentially anything that made a single server "special", but making "special" servers is a bad idea in the first place. Pets vs. cattle, etc. etc. Specific points.. > Must build an image before deploying and it takes time, so deploys are slow (of course we use CI to do it, it's not manual). How large are your images? Build times can be very variable, but if you have a good base image it can be very fast. I think on average my build times have been about 5-20 seconds. There's definitely an art to it, but dockerfiles are not in any way complicated and setting up a multi-stage build to cache the expensive parts (compiling C libs, etc.) is fairly straightforward. > If I need quick hot fix RIGHT NOW, I can't just log in, change couple of lines and restart, must go through full deploy cycle. Oh my god, just don't do this. This is such an antipattern. If you think you need this you're really doing things wrong. If you need a hotfix RIGHT NOW, you should hit that fancy roll-back button (which containers and their orchestrators make easy..) and then figure out what went wrong, instead of trying to use vim to fix some line of code in production. > Must remember that launched containers do not close when ssh breaks connection and they can easily linger for a couple of weeks. Huh? TBH I don't understand why you would be expecting a closed SSH connection to shut it down -- these things are almost always meant for running a service -- but this is a really minor thing. It sounds like you just don't want to change any of your current habits, not that the habits that containers encourage are somehow worse.
