A small docker image) for python.
$ 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", "./your-daemon-or-script.py" ]
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
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)
