@gsuberland yeah there were never problems with library version clashes in Python, perl, ruby .... 🙄 😛
containers also provide a decent level of isolation from the underlying host, and other processes running on the host, which can be very handy.
@raesene those problems didn't go away when we invented containers though. plenty of stuff relies on libs which then desync their version requirements from each other and cause problems within the container. the solution to that is stuff like venv, and better cross-version interop in language tools, not "pack a whole virtual machine (or near as damnit) to go with it, with all the extra complexity that entails".
@gsuberland @raesene
Well, the tools I use requre venvs, which are on the same scale as minimalistic linux image on top of which their docker images are built. And given that one package which should be installed from git and was updated last time in 2016 can cause the whole library hell in the system - docker is a tool of choice for many things.
