Chatops (Operations automation with a bot)

1 - About

Chatops:

  • The important phases of development cycle are brought in one place, in one room, a chat room through a bot.
  • Automating common operations task with a bot.
  • Breaking communication wall between different teams.

The bot is the primary control for the whole infrastructure.

The chat becomes a console

By placing tools directly in the middle of the conversation, everyone is pairing all of the time. Teaching by making things visible.

3 - Chat

  • Campfire is a web-based group chat tool that lets you set up password-protected chat rooms in just seconds. Invite a client, colleague, or vendor to chat, collaborate, and make decisions. Link to a room on your intranet for internal communications.

Ryan wrote Hubot at Github.

4.1.1 - rolling a new version


git checkout -b git-gh13
# bump version number
git commit -am 'Bump git version'
git push origin git-gh13
# create pull request

Change as passed CI (ie Build was succesful)

  • Deploy

hubot deploy puppet to production

  • noop means simulate what happens on that branch git-gh13 against the file server fs1, noop mode simulates the changes

hubot puppet noop git-gh13 fs1 


hubot puppet force git-gh13 fs1


hubot graph me -1h @collectd.load(fs1)

  • The pull request is good, we want to push it in production (everywhere)

#merge pull request

  • To ensure that the master is green

ci runs
# Build 1087 (eragaf66&&) of puppet/master was successful (399s)

  • When the CI passes, the code is deploy in production

auto deploy

  • Now a new version of git is on master. It has been shipped everywhere.

# Puppet shipped it on a interval but you can push it 
hubot puppet force production fs

  • Graph of everything (of all file servers)

hubot graph me -1h @collectd.load(fs*)

  • Logs to make sure that we didn't break anything.

hubot log me hooks github/github
