dockerfile-examples

See: Virtualenv (for Python), Snappy, Flatpack The main advantage of docker, as far as my understanding goes, is more of a prebuilt system configuration thing. Need a database? Load the prebuilt PostgreSQL image onto the respective machine. One thing I think should get more use in general is that Dockerfiles are essentially completely reproducible scripts[1]. Too many companies I've seen still use Word documents full of manual steps one can easily get wrong for all their machine setups (especially in the Windows world). If you want to test something quickly, you're bogged down for a day. [1]: example: https://github.com/kstaken/dockerfile-examples/blob/master/m...

And then of course the system inside the container needs to start up, configure, run init scripts, ... Did you count that in those 100 syscalls ? Take the example here: https://github.com/kstaken/dockerfile-examples/blob/master/n... Which does something a lot of these functions will do : get nodejs, use it to run a function. Just the apt-get update, on my machine just those instructions, ignoring actually running the function (because it's insignificant) does close to 1e6 syscalls.
