jah: A Ruby repository from nofxx

Talk to/config your machines. Like a god.

Install

gem install jah

To create a config repo:

jah new <path>

To create a config file for XMPP:

Just run it for the first time to create a config file. Use jah install to force the wizard again. Jah will try to find a jah.yaml file on ~/.jah or /etc.

Support

ArchLinux (tested)
Mac OS X (tested)
CentOS (tested)
Debian (tested)
BSD

Gems required for config mode:

Capistrano

Gems required for XMPP mode:

Blather
EventMachine

Modes

Jah has two modes you can use separately:

Config

Jah new will create a tree like this:

 |- hosts.yml
 |- config
 |  |- deploy.rb
 |- example
 |  |- deploy.rb
 |  |- files/
 |  |- scripts/

THIS IS ALL SUBJECT TO BIG CHANGE! Some nice DSL coming soon hehe...

hosts.yml

In hosts.yml, you inform all your servers and which profiles you want in them.

config

Config deploy is just a "system wide" place for your custom tasks.

profile

Example is a sample profile: Deploy works as you might expect, you can define tasks and use capistrano syntax all along.

Daemon

Notification/command dispatch via XMPP!

XMPP

Chat with your server with your favorite XMPP client (pidgin, adium..) Receive reports and failures realtime! Send commands and

POST

The old school way. Set up a Jah Web Server, and give Jah it`s address. Jah will periodically post info. You can send commands through SSH.

DUMP

AkA: Security freak. Jah just writes to tmp/ or whatever a dump file, Jah Web securely connects (scp) and downloads the data to parse.

XMPP Bot

Execute sh commands:

pwd
$> /home/jah

Executing ruby statements:

! 2 + 2
=> 4

! def foo; "hi"; end
! foo
=> "hi"

Execute Jah commands:

cpu?
msweet: 0.14, 0.25, 0.14

mem?
msweet: 53%

net?
7 connections
[ips...]

ok?
[Personalized cool phrase...]

Group session:

me: ok?
msweet: I'm fine, thanks..
ssaint: Kinda busy right now..
naomi: I need you! NOW!

System commands

PubSub

Create a pubsub:

pub create foo
jah: Done.

Publish to it:

foo: pubbin and dubbin from jah!
jah: Published.

My pubs:

pub mine
jah: Pubsubs
Owner: foo

All pubs:

pub all
jah: All Pubsubs
=> /foo
=> /bar

Subscribe to bar:

pub sub bar
jah: Done.

Unsubscribe to bar:

pub unsub bar
jah:Done.

Destroy a pub:

pub destroy foo
jah: Done.

Use God?

God commands

Start, stop, restart, monitor and unmonitor words on the beginning of a phrase will make Jah add a "god" on the front of it, making it trivial to work with your services:

start nginx
restart nanites
unmonitor postgresql

Note on Patches/Pull Requests

Fork the project.
Make your feature addition or bug fix.
Add tests for it. This is important so I don't break it in a future version unintentionally.
Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
Send me a pull request. Bonus points for topic branches.
