This project is DEPRECATED and not any longer supported
Package Python software as an RPM including all dependencies (even the interpreter).
This solves the problem of an outdated Python (2.6) on RHEL since we can now deploy self-contained RPMs that are independent.
The source of truth for the software to be installed is the Python package index at: https://pypi.python.org/pypi
See the file
snakepit.yaml for details on how to build a spec file for
You can then:
$ snakepit snakepit.yaml
Which will produce a
For more information on options:
$ snakepit -h
Building the resulting
The resulting spec file requires the
make-opt-writable rpm which you can
build using the
make-opt-writable.spec (included in repository) file. This is
required due to very low-level reasons related to the way in which miniconda
Furthermore, the spec file is of a special flavour of
svn2rpm which can be
found at: https://github.com/immobilienscout24/svn2rpm/. You may not yet be
able to use the spec files w/o this tool and the surrounding boilerplate.
How does it work?
For a given product to build an RPM for---let's call it
snakepit will create a spec file. The spec file works as
- Install anaconda/miniconda to
- Install the product into that installtion using
- Setup any symlinks from
- Copy the whole installation into the buildroot
It is available from PyPi: https://pypi.python.org/pypi/snakepit
To install, do:
$ pip install snakepit
Use PyRun as Python distribution to build a spec-file
You do not need any make-opt-writable rpm or svn2rpm. Simply build your spec- file in userspace and reduce the rpm size more than by half.

Getting in touch
Please use the conda mailinglist at: https://groups.google.com/a/continuum.io/forum/#!forum/conda
This tool is in an early alpha stage and the output is guaranteed to change. Feedback, comments and pull-requests welcome, but please do bear in mind that, this is work in progress and therefore probably full of many, many horrible bugs.

- Install optional dependencies, e.g.
- What if we want to install conda packages?
- What if we have a complex dependency chain?
- What if we want to install multiple products?
- Ability to package additional things, such as bash completions, cron-jobs and so on.
- Ability to install from a git-repo
- Ability to run all tests before creating the RPM (usually not possible if from PyPi)
- Add a 'minimum_snakepit_version' number and abort if snakepit is too old.
- Include git-hash of snakepit in spec
- Include version number of conda-dist
- Download .sh installer via Source0
- What about the illegibility of the spec file template
- Decouple from make-opt-writable
- Decouple svn2rpm
--posthooks for the spec file
- Release number should also contain the python version
- Augment the description with complete metadata
- Automagically determine the symlinks. (either by doing deltas during install, or by inspecting the metadata.)
- Change package name from
conda-distto something the user can select.
- In case we want to install c-extensions, we may need to add c-compiler and
other things to the
- Specify template file via
- Allow outputing the spec file on stdout using
- Decide if it should be '--build' or '--release'
- If no file specified, it should look for a
The idea is to have a one-step conversion from any Pypi software to an RPM package.
- Automatic choices where possible, e.g. for the Python interpreter, symlinks for bin/* files etc.
- Naming conventions: ** RPM Name = Pypi name ** RPM Version = Pypi version ** RPM Release = Build Nr, Python Interpreter Version etc. ** RPM Licence = Licence from PyPI ** RPM Summary = First line of Package description from PyPi ** RPM Description = Full description from PyPi + Metadatasection at the end ** RPM Packager = logged in user + snakepit
- Consider "snakepyt" as name
- Figure out how to get the cram-plugin to write coverge data too
- Maybe we can delete things from the miniconda install that are not required
since it is now static. E.g. stuff in
pkg. This would help to reduce the size of the final RPM.
- Consider https://github.com/pyinstaller/pyinstaller as an alternative
- Delete pip and conda after installing everything to remove the temptation to install things as root on the box. In fact, perhaps make a 'debug' yaml flag that allows to craete such packages.
