DEVELOPMENT STOPPED. EOL.

bleetz

Fast KISS deployment tool.

Why bleetz ?

I tried Capistrano, Minas. They are great (No irony) but not for me.

I prefere when I know what is going on.

Requirements

You need rubygems installed.

Tested with Ruby:

• 1.8.7
• 1.9.2
• 1.9.3
• 2.0.0-preview1

Installation

gem install bleetz

or for development:

git clone https://github.com/TibshoOT/bleetz.git
gem build bleetz.gemspec
gem install ./bleetz

Configuration

There are two files. Main configuration file and .bleetz file:

• Main configuration is located where you want.
• .bleetz has to be in bleetz binary call directory.

For example:

$ mkdir -p ~/bleetz
$ touch ~/bleetz/bleetz.conf
$ mkdir a_project_path
$ cd a_project_path
$ echo 'config: \'~/bleetz/bleetz.conf\'' > .bleetz
$ bleetz -l

Following options have to be written in ~/bleetz/bleetz.conf in our example.

Not the most important but...

The most helpful to understand your configuration, comment !

# This is a fraking great comment !

SSH configuration

Bleetz has wrapped net-ssh library options to configure your ssh connection(s).

Mandatory:

Option	Conf symbol	Type
Host	:host	String
Username	:username	String

Optionnal:

These options are set by default but you can overide them (if you are sure what you are doing...)

Option	Conf symbol	Type	Default value
Port	:port	Integer	22
Proxy Command	:proxycmd	String	empty
Timeout	:timeout	Integer	10
Private Key	:keys	Array of String	["~/.ssh/id_dsa", "~/.ssh2/id_dsa", "~/.ssh/id_rsa", "~/.ssh2/id_rsa"]
Compression	:compression	String	'none'
Compression level	:compression_level	Integer	6
Encryption	:encryption	String || Array of String	'3des-cbc'
Host key	:host_key	String || Array of String	'ssh-dss'

Check example file here.

Generally, you don't have to change these options except :port, :timeout and :keys.

How to configure

You have to use set function. In order to configure a user, you can do this:

set :username, 'a_login'

Actions

This is the main feature of Bleetz. Actions.

Actions are kind of functions where you write shell script that will be executed over SSH.

Bleetz has been coded to deploy code but you can use it for different purpose (restart some services, backup, etc).

Defining action

To define an action:

action(:action_name) {
  # blabla
}

or

action :action_name do
  # blabla
end

If you want to put a description, you can do this:

action(:action_name, "a fraking awesome description") {
}

You will see why you've put this after :action_name (See Usage chapter, -l option).

Write shell script

Imagine that you want to write an action that print "42".

action(:forty_two) {
  shell "echo '42'"
}

This part will execute echo 42 after SSH connection.

Yo dawg, I heard you like to call action, so I put an action in an action so...

You can !

Taking our previous :forty_two action:

action(:forty_two) {
  shell "echo '42'"
}

Imagine that you want print 42 in another action, :new_action here, but you want to stay DRY:

action(:forty_two) {
  shell "echo '42'"
}

action :new_action, "A description !" do
  shell "echo 'I will print 42 !'"
  call :forty_two
end

That's it. If you call :new_action, 'I will print 42 !' and '42' will be printed after SSH connection. :)

Callbacks

If you want to run LOCAL shell scripts with bleetz before or after action, you can !

before(:test) {
  shell "echo 'Command will be runned in local before ssh'"
}

action(:test) {
  shell "echo 'Command over ssh'"
}

after(:test) {
  shell "echo 'Command will be rrunned in local after ssh'"
}

After and Before callback are called ONLY FOR THE MAIN action. Don't worry about calls in action.

Example, if you have defined this:

before(:test) {
  shell "echo 'Command will be runned in local before ssh'"
}

action(:test) {
  shell "echo 'Command over ssh'"
}

after(:test) {
  shell "echo 'after ssh command in local'"
}

before(:testbis) {
  shell "echo 'Command will be runned in local before ssh'"
}

action(:testbis) {
  call :test
  shell "echo 'Command over ssh'"
}

If you call bleetz test, that will execute before(:test), action(:test) and finally, after(:test).

If you call bleetz testbis, that will execute before(:testbis), action(:testbis), action(:test), that's all.

.bleetz file (YAML)

At the moment, there is only one option. Mandatory if you don't use -c command option.

Attribute	Argument	Explanation
config	A configuration filee path	Tell bleetz binary to check configuration file without giving -c .

Example:

$ cat .bleetz

You should see:

config: 'a/path/to/bleetz/configuration/file'

Usage

It's important to notice that action name has to be put at end of command.

Available options

Option	Need an argument ?	Explanation
-c	Yes, a configuration file	If you want to skip .bleetz file, use -c option.
-h	No.	Display help.
-l	No.	List configured actions in configuration file.
-s	No.	Test configured SSH connection.
-t	Yes, action's name.	Test actions, just print commands.
-v	No.	Verbose mode.
-V	No.	Display version.

Examples

List available actions:

bleetz -c /etc/bleetz.conf -l

Test SSH connction (with .bleetz file):

bleetz -s

Test :deploy action:

bleetz -c /etc/bleetz.conf -t deploy

Exexute :deploy action in verbose mode (with .bleetz file):

bleetz -v deploy
