= fog

fog helps you interact with cloud services. fog is a work in progress.

== Install

  sudo gem install fog

== Getting Started

You can start stumbling around as soon as you install with the fog command line tool.
After installing, just type 'fog' to get started.
If you don't have credentials setup it will let you know what to do.

Then just start playing around, fog should let you know if you are forget things.

For example if you try to create a server but leave out stuff:

  server = AWS.servers.create

You'll get reminded that things are missing.

  ArgumentError: image_id is required for this operation

So just add the missing stuff and you are off to the races:

  server = AWS.servers.create(:image_id => 'ami-5ee70037')
  # you might also want a security group, which would go more like this:
  # AWS.servers.create(:image_id => 'ami-5ee70037', :groups => ['secure'])
  # NOTE: currently you can only have one group at boot time, so the first
  # element of the array will be used (and the rest will be disregarded)

But don't forget to cleanup or you'll regret it when you get the bill:

  server.destroy

Rinse, repeat, enjoy!

== Working with Servers

Lets boot up a server on EC2

  require 'fog'

  # initialize a connection to Amazon Elastic Compute Cloud
  connection = Fog::AWS::EC2.new(
    :aws_access_key_id => id,
    :aws_secret_access_key => key
  )

  # boot a gentoo server
  server = connection.servers.new(:image_id => 'ami-5ee70037')

  # wait for it to be ready to do stuff
  server.wait_for { ready? }

  # DO STUFF

  # shutdown the server
  server.destroy

Now we will try again, but with Rackspace

  # initialize a connection to Rackspace Servers
  connection = Fog::Rackspace::Servers.new(
    :rackspace_api_key => key,
    :rackspace_username => username
  )

  # boot a gentoo server (flavor 1 = 256, image 3 = gentoo 2008.0)
  server = connection.servers.new(:flavor_id => 1, :image_id => 3, :name => 'my_server')

  # wait for it to be ready to do stuff
  server.wait_for { ready? }

  # DO STUFF

  # shutdown the server
  server.destroy

== Working with Directories and Files

  require 'fog'

  # initialize a connection to Amazon Simple Storage Solution
  connection = Fog::AWS::S3.new(
    :aws_access_key_id => id,
    :aws_secret_access_key => key
  )

  # create a directory
  directory = connection.directory.create(:name => 'directoryname')

  # create a new file in your directory
  directory.files.create(:key => 'filename', :body => 'filebody')

  # connect to your directory
  directory = connection.directories.get('filename')

  # get your file
  file = directory.files.get('filename')

  # delete the file
  file.destroy

  # delete the directory
  directory.destroy
