I love docker, it of course comes with some inefficiencies, but let's be real, getting an app to run on every possible environment with any possible other app or configuration or.... that could interfere with yours in some way is hell.

In an ideal world, something like docker is indeed not needed, but the past decades have proven beyond a doubt that alas, we don't live in this utopia. So something like docker that just sets up a private environment for the app so that nothing else can interfere with it.... why not? Anything i've got running on docker is just so stable. I never have to worry that any change i do might affect those apps. Updating them is automated, ...

Not wasting my and the developers time in exchange for a bit of computer resources, sounds like a good deal. If we find a better way for apps to be able to run on any environment, that would of course be even better, but we haven't, so docker it is :).
