SyncWrap

Description

A rather direct provisioning and deployment system in ruby, bash over ssh, and rsync. SyncWrap is a refreshingly straightforward, DSL-free non-framework with no central server or repository requirements. The “magic”, if any, lies in the elegant component model, the shell command queue, and a few powerful methods like rput (augmented rsync).

Features

Synopsis

Simplest example. Place the following in a sync.rb file:

class Greeter < SyncWrap::Component
  def install
    say_it
  end

  def say_it
    sh <<-SH
      echo "Hello from #{host.name}"
    SH
  end
end

host 'localhost', Greeter.new

Try it via the command line:

gem install syncwrap
syncwrap --help
syncwrap -f ./sync.rb --list  # -f default; list
syncwrap                      # Run it
syncwrap -v                   # Run it with full verbose output
syncwrap -v Greeter.say_it    # Without Greeter#install default

Output from syncwrap -v (minus the terminal color):

== localhost #<Module:0x00000001e95678>::Greeter#install: enqueue
<-- sh localhost (-v coalesce live)
echo "Hello from localhost"
Hello from localhost
--> Exit 0 (success)

See more elaborate examples, including ec2 provider support, in the examples directory and LAYOUT.

Components

Component hierarchy implementing SyncWrap::Distro, for common methods like dist_install and other distribution-specific behaviors:

Components implementing #install:

Component wish list

The above only represents my more recent project needs. Pull requests to add, for example, the following would be well received:

SyncWrap makes it reasonable to implement any of the above yourself.
