A Continuous Packaging Pipeline

A list of tools mentioned in my Ignite talk from Devopsdays Rome 2012 on a continuous packaging pipeline, with links and short description for each tool.

The talk slides are at https://speakerdeck.com/mpasternacki/a-continuous-packaging-pipeline; a longer blog post will be written soon.

Vendorificator

Available at https://github.com/3ofcoins/vendorificator/ or with gem install vendorificator

Include third party modules in your git repo, using pristine branches to sanely maintain local changes, upgrades, and merges.

# Trace 'print' statement calls cluttering your test suite output.
#
# It is not that simple to track 'print' statement in Python 2.x - it
# cannot be monkey-patched itself, because it's not a function. So we
# override sys.stdout and check the backtrace when stdout is written
# to.
#
# The overload happens only if TRACE_PRINT environment variable is
# set. By default, only the offending file name and line number is
# printed; if TRACE_PRINT environment variable is set to 'traceback',

# Chef resources describing how to set up package repository server,
# simplified fromactual cookbook (not open sourced yet). Sets up apt
# repository in /srv/apt directory, with system user "apt-repo". Packages
# are GPG-signed to prevent apt-get from complaining on every install.
# 
# Directory /srv/apt should be reachable to clients via http or other
# means. This is left as an exercise for the reader.

#!./bin/knife exec

# A knife exec script to change chef node's name, preserving all the attributes.
#
# Usage: knife exec rename-node.rb old-name new-name
#
# Script retrieves the Node object, changes its 'name' attribute,
# creates new Node object with updated name and rest of attributes
# untouched. Then it deletes old Node and Client objects from
# database, and logs into the server to update it:

# Example usage:
# perl_module_build "0.3601"

define :perl_module_build do
  execute "/usr/local/bin/cpan_install Module::Build" do
    cwd "/root"
    path [ "/usr/local/bin", "/usr/bin", "/bin" ]
    not_if { `perl -mModule::Build -e 'print $Module::Build::VERSION'`.to_f >= params[:name].to_f }
  end

#
# check_with_hysteresis.pl - hysteresis for nagios service checks' limits
#
# Usage: check_with_hysteresis.pl $LASTSERVICESTATE$ default check --- STATE1 check for state1 --- STATE2 check for state2 ...
#
# If $LASTSERVICESTATE$ is STATE1, "check for state1" will be
# executed, if it's STATE2, "check for state2" will be executed, and
# so on; if state is undefined, "default check" wil be executed.

# knife.rb config snippet to make knife ssh command use your own login

# Data bag items in 'projects' can declare 'include_recipes' property

# to be declared in 'depends'. This code loads the data bag JSON from
# files, and declares all needed dependencies.
