ツール "fireap" を作った

“fireap” in a nutshell

❏ O(log N) … N = node number❏ Propagative task runner on Consul Cluster

Then, what about “grifork”

❏ O(log N) … N = node number❏ Propagative task runner via ssh❏ https://github.com/key-amb/grifork❏ Blog:

❏ ssh と rsync だけで Tree Deploy を実現する "grifork" を作った

How “grifork” works?

Concept of “Tree Deploy”

Two modes to run “grifork”

1. “Standalone mode”○ Require grifork only on the task-running host

2. “Grifork mode”○ Require grifork on every node

Standalone mode 1/3

Standalone mode 2/3

Standalone mode 3/3

Grifork mode 1/3

Grifork mode 2/3

Grifork mode 3/3

Quickstart

% gem install grifork% edit Griforkfile% grifork

Configure by “Griforkfile”branches 4

#mode :standalone

log file: 'grifork.log'

hosts ['web1.internal', 'web2.internal', 'db1.internal', 'db2.internal', ...]

local do

rsync '/path/to/myapp/'

end

remote do

rsync_remote '/path/to/myapp/'

end

See examples for more info

Changes in v0.2 ~ v0.5

❏ Released as a RubyGems❏ https://rubygems.org/gems/grifork

❏ Enable to configure Parallel, ssh and rsync options by Griforkfile

❏ Enable to configure tasks which runs at first in the job or at last

Summary

❏ “grifork” is an easy way to speed up deployment

❏ Enjoy!

Thank you!
