New recipe, collective.recipe.buildoutcache

This recipe generate a buildout-cache archive. We use pre-generated buildout-cache folder for speed up buildout duration.

Introduction

This recipe generate a buildout-cache archive. We use pre-generated buildout-cache folder for speed up buildout duration. The archive contains one single buildout-cache folder. In this folder, there are 2 folders:

  • eggs: contains all eggs use by your buildout except eggs which have to be compiled.
  • downloads: contains zip eggs which must be compiled (as AccessControl, lxml, Pillow, ZODB, ...)

Before starting a buildout, we download and extract buildout-cache and use it on our buildout. We add eggs-directory and download-cache parameters on buildout section like this:

[buildout]

eggs-directory = buildout-cache/eggs download-cache = buildout-cache/downloads

 

Use case

In our organization, we have a Jenkins server. We created a Jenkins job which generate buildout-cache.tar.gz2 every night and push it into a file server.

We also use Docker, our Dockerfiles download and untar buildout-cache before starting buildout, so creation of docker image became very faster !

 

How it works

Simply, you have to add an parts with this recipe on your buildout project.

Like this :

[buildout]

parts = ... makebuildoutcachetargz [makebuildoutcachetargz] recipe = collective.recipe.buildoutcache

You can use some parameters for changing name of your archive, use another working directory than ./tmp or use another buildout file than buildout.cfg for eggs downloads, See https://github.com/collective/collective.recipe.buildoutcache.

For recipe installation you can make this command line:

./bin/buildout install makebuildoutcachetargz

And start recipe script:

./bin/makebuildoutcachetargz

 

Conclusion

Use collective.recipe.buildoutcache and decrease time lost with your buildout ;)
