docker-static-python

This repository is a fork of the update python version branch in my fork of andrew-d/static-binaries. The goal of this repository is to separate out the Python parts from the upstream collection of packages.

Version

This Docker image provides Python-2.7.15rc1 with the following modules and software statically compiled in to the python binary:

Usage

By default the image will run python -sS /entrypoint.py but if you would prefer a Python shell invoke:

$ docker run -ti thedoh/static-python:2.7.15rc1-r1
Python 2.7.15rc1 (default, May 17 2018, 15:15:27)
[GCC 5.3.0] on linux2

psutil Notes

The package is included to illustrate the possibility of compiling third party modules into the Python static image. The psuutil package is patched with two patches (below) to force the psutil Python library code to not look in its directory (from . import) and rather to anywhere the requirement can be met (such as from within the python binary).

A common use case will be to pip install some set of requirements for use. Since some of those requirements may have C code to compile it is thus a requirement to statically compile that code into the python binary because there are no shared Python objects to link against. The inclusion of psutil demonstrates this process.

Entrypoint.py

A sample entrypoint.py to call an app using Factory pattern might be:

import sys
import os

sys.path.append("/usr/src/app")

os.chdir("/usr/src/app")

from your.app import make_app

app = make_app()

app.run()

If you prefer to execv instead:

import sys
import os


os.chdir("/")

os.execv("/python", ["-s","-S","/myapp.py"])
# No code runs after here

Or subprocess:

import sys
import os


os.chdir("/")

import subprocess

subprocess.call(["/python", "-s","-S","/myapp.py"])
# Code execution continues
