grifork - fast propagative task runner -
- 1. “grifork” - fast task runner via ssh - @key_amb at the 40th Ginza.rb #ginzarb
- 2. Who am I ? ❏ @key_amb ❏ Software Engineer ❏ Serverside, Web ❏ https://github.com/key-amb ❏ https://rubygems.org/profiles/key-amb
- 3. Before “grifork” - “fireap” ❏ https://github.com/key-amb/fireap ❏ Consul クラスタ上で動作する S3 非依存の pull 型デプロイ ツール "fireap" を作った
- 4. “fireap” in a nutshell ❏ O(log N) … N = node number ❏ Propagative task runner on Consul Cluster
- 5. 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
- 7. Concept of “Tree Deploy”
- 8. Two modes to run “grifork” 1. “Standalone mode” ○ Require grifork only on the task-running host 2. “Grifork mode” ○ Require grifork on every node
- 12. Grifork mode 1/3
- 13. Grifork mode 2/3
- 14. Grifork mode 3/3
- 15. Quickstart % gem install grifork % edit Griforkfile % grifork
- 16. 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
- 17. 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
- 18. Summary ❏ “grifork” is an easy way to speed up deployment ❏ Enjoy!
- 19. Thank you!
