DPP

Distributed puppet runner (WiP)

A small toolbox for running distributed puppet (each node downloads repo and runs it without central puppet master)

Currently implemented features:

• Git as VCS
• Git GPG signing supported (list of allowed keys per repo)
• Ability to prepare deploy package ( dpp package, output in /tmp/dpp.tar.gz )
• Locking (only one puppet run at a time even if multiple instances are running)
• Signal support (USR1 to run puppet, USR2 to run repo update

Todo:

• ability to connect to main demon and run with "hijacked" output (puppet running by demon piping output to CLI tool)
• some kind of distributed KV support (+ Puppet glue code) to support inter-node coordination
• post last run stat to other node(s) for monitoring
• branch support

Building

make

Then put example config in /etc/dpp/config.yaml and run it

How it works

• Git fetch repos
• If gpg is enabled, verify origin/ branch for commit (requires last commit on top of branch to be signed)
• if commit is ok check it out to local dir
• generate a list of module paths for puppet, then run puppet with generated module and manifest path, repeat
