Python 2.7 script to static binary

Notes V1

to get a standalone python you need to link all the modules staticaly
thius requires a custom build, because its dynamic in nature.
after the static lib's are overcome you run into some weird legacy code...
glibc.. a needed component to python is tricky it loads other modules
dynamically, and im not sure if the names are hard coded or not.
from what I understand, depending on the compiler there are 2 flavors of glibc, old/new
but you need a custom build for each os you want to drop it in.
so, a cent 5,6,7 build. but maybe diff vers of glibc too?
more testing to come. research says either way you should have 90% coverage per os
insanity...

Description

This docker creates a static version of python 2.7.16.
It uses cython to compile the python script into c code.
It compiles the c code and links it with the static pythoin binarys.
The output is a static / portable/ standalone binary.

Environment variables

PY_SCRIPT=script in mounted volume to compile
PY_SCRIPT_OUTPOUT=name of the binary to drop into mounted volume

Use

You must mount a volume to the "/build". This is where you drop your source .py file.

docker run -it \
           -v $(pwd)/build/:/build/ \
           -e PY_SCRIPT=my_script.py \
           -e PY_SCRIPT_OUTPUT=my_bin \
           pybin-onator

Building the image from scratch

git clone https://github.com/chris17453/pybin-onator.git
cd pybin-onator
make build

Testing

make test

Output

In the mounted directory you will have 4 new files.
File #1 -> my_script.py.c
File #2 -> my_bin
FILE #3 -> cython.output. my_script.py to my_script.py.c
FILE #4 -> gcc.output. The binary compiler action

Notes

these modules need help with deps that are not static, they failed
these modules dont exist...
