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')

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')
# you might also want to add the server to security groups, which goes like this:
# AWS.servers.create(:image_id => 'ami-5ee70037', :groups => ['web', 'db'])

# 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('directoryname')

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

# delete the file
file.destroy

# delete the directory
directory.destroy
