Based on debian:stretch-slim, this minimal image comes with the latest Python 2 and/or 3 versions pre-installed. A default docker user is also configured with the necessary permissions for running pip install --user . Useful for running any server-side code that does not require a Desktop environment.

Common applications include test-runners that require versions of Python 2 and/or Python 3 installed (e.g tox) or any environments that require just one version of Python 2 and Python 3 installed (e.g. jupyter notebook servers).

There are two main tags currently maintained:

• transcriptic/python-minimal:2-3
• transcriptic/python-minimal:35-36-37

For 2-3, images from https://hub.docker.com/_/python/ are used and parameterized with $PYTHON2_VERSION and $PYTHON3_VERSION for specifying required versions of Python 2 and Python 3 respectively. This is useful when a single version of Python 2 and Python 3 is required.

For 35-36-37, this contains the latest builds of Python 3 supported, and is useful for testing environments that require Python 3.5, Python 3.6 and Python 3.7.

In all cases, the build arg $uid is used for specifying the build-user, which is helpful when executing with a mounted volume for continuous integration tools such as Jenkins

# Running `tox` on a mounted volume
docker build --build-arg uid=1000 -t lib_test .
docker run --user 1000 -v `pwd`:/home/docker/lib_test lib_test tox

# Specified versions of Python 2/3 (including minor versions)
docker build --build-arg PYTHON2_VERSION=2.7.14 PYTHON3_VERSION=3.6.7 -t my_lib_test .

This is currently hosted on https://hub.docker.com/r/transcriptic/python-minimal/
