Buildout Examples

Examples from Fulvio Casali

Sample config/buildout.cfg.tmpl

This file is checked in to the config folder inside the buildout root.  First thing after checking out the buildout, one would copy it up one level, rename it to buildout.cfg, and uncomment the desired parts. In particular, one would uncomment the line config/devel.cfg for a local development instance, or config/staging.cfg or config/prod.cfg for a staging or a production site, respectively.

 [buildout]
extends =
#    config/prod.cfg
#    config/staging.cfg
    config/devel.cfg
#allow-hosts =
#    pypi.python.org
#    dist.plone.org

## Optional devel.cfg support.  If you're using devel.cfg from above,
## you can uncomment lines below to enable

parts +=
#    roadrunner
#    ptprofiler
#    zopeprofiler
#    zptdebugger
#    deadlockdebugger
#    ipzope

[instance1]
zcml-eggs +=
#    plone.reload
eggs +=
# Uncomment if using deadlockdebugger
#    threadframe
products +=
#    ${ptprofiler:location}
#    ${zopeprofiler:location}
#    ${zptdebugger:location}
# Also Uncomment threadframe in eggs above if using deadlockdebugger
#    ${deadlockdebugger:location}

SVN ignored files

Please note that the file buildout.cfg in our buildout root is never checked in, to avoid breaking production installations:

>svn propget svn:ignore
#
# applied by: svn propset svn:ignore -F ./IGNORE.txt .
#
.installed.cfg
.mr.developer.cfg

Sample config/varnish.cfg

[buildout]
extends = zeo.cfg

[varnish-build]
recipe = plone.recipe.varnish:build

[varnish]
recipe = plone.recipe.varnish:instance
backends = ${instance1:http-address}
bind = 127.0.0.1:8000
cache-size = 512M

Sample config/zeo.cfg

Please note that this config file does a bunch of stuff:

  • It configures ZEO
  • It configures two different backup cron jobs, a daily and a weekly one
  • It configures logrotation
  • It configures a cron job to restart supervisor, whenever the host is rebooted
  • And it also configures the Zope production instance parameters

The z3c.recipe.usercrontab recipe is a handy way to set up cron jobs.  Just note that the cron jobs will be installed for the user who runs buildout, so be careful to check what user you are currently logged in as.

Also, see below for the logrotate.conf.tmpl file.

Sample etc/logrotate.conf.tmpl

You will want to check this file in to SVN.  The file logrotate.conf is generated automatically by buildout expanding the variables in the ...tmpl file, and should not be checked in.
