A small docker image) for python.

The total image size is 20.35 MB. This is achieved by using the great progrium/busybox as base image and the super small Egenix PyRun.


$ docker run -t -i --rm elyase/pyrun:3.4 python
eGenix PyRun 3.4.1 (release 2.0.1, default, Aug 26 2014, 11:51:10)
[GCC 4.6.4]
Thank you for using eGenix PyRun. Type "help" or "license" for details.


For a new image create a Dockerfile in your Python app project:

FROM elyase/pyrun:2.7
CMD [ "python", "./" ]



The official docker python image is too big (900 MB), the smallest python docker image runs at several hundred MBs. The reason for that is that a typical Ubuntu base image is more than 200MB in size plus ~100Mb for a basic python installation.

When is this useful?:

You have a small pure python script that you want to test/run in an isolated docker container.

Which python version is installed in the container?:

There are two image tags, one for python 2.7 and one for python 3.4. Ex:

$ docker pull elyase/pyrun:3.4

What are the drawbacks?:

Please refer to PyRun's page. Esentially: it is somewhat difficult to install dependencies and some less used modules are missing like readline, tkinter, multiprocessing, etc. In general everything should run like in a standard python distribution.

Can I install packages?

No, but I am planning on also making a pip compatible image.

Is this the smaller docker image for python?

No, this one is smaller (8.5MB)

Thank you for creating this tiny image that includes Python 3.4. It is brilliant and much smaller than the official Python images (and other DIY images) on DockerHub.
