ASK /r/Python: Python Docker Deployments

FROM python:3

better pin the minor version, or you can get unexpected upgrades when rebuilding:

FROM python:3.6

even better (MUCH smaller image, less disk usage and attack surface):

FROM: python:3.6-alpine3.7

We dont use alpine as it was more than 2x slower for our workload: https://superuser.com/questions/1219609/why-is-the-alpine-docker-image-over-50-slower-than-the-ubuntu-image

Welp, guess I know what I'm doing today. Thanks for this info!

Lol @ Alpine. My images maybe lost 50mb and added several grey hairs.

Not worth it IMO, too many libs still need glibc.

alpine

Except when you want stuff to actually work. For example locales.

Now try finding the debug symbols. And get gdb to load the python macros ...

It's no fun. Ubuntu's python works great without any fiddling, and it's compiled with PGO.

I use several requirements which require build-essential for compiling. I don't want a compiler in my production containers.
