This is the official Opscode Knife plugin for Linode. This plugin gives knife the ability to create, bootstrap, and manage Linode instances.

Be sure you are running the latest version Chef. Versions earlier than 0.10.0 don’t support plugins:

gem install chef

This plugin is distributed as a Ruby Gem. To install it, run:

gem install knife-linode

Depending on your system’s configuration, you may need to run this command with root privileges.

In order to communicate with the Linode API you will have to tell Knife about your Linode API Key. The easiest way to accomplish this is to create some entries in your knife.rb file:

knife[:linode_api_key] = "Your Linode API Key"

If your knife.rb file will be checked into a SCM system (ie readable by others) you may want to read the values from environment variables:

knife[:linode_api_key] = "#{ENV['LINODE_API_KEY']}"

You also have the option of passing your Linode API Key into the individual knife subcommands using the -A (or --linode-api-key) command option

# provision a new m1.small Ubuntu 10.04 webserver  # FIXME: change from EC2 to linode
knife ec2 server create 'role[webserver]' -I ami-7000f019 -f m1.small -A 'Your AWS Access Key ID' -K "Your AWS Secret Access Key"

Additionally the following options may be set in your ‘knife.rb`:

• linode_flavor

• linode_image

• linode_kernel

• ssh_password

• bootstrap_version

• distro

• template_file

This plugin provides the following Knife subcommands. Specific command options can be found by invoking the subcommand with a --help flag

Provisions a new server in Linode and then perform a Chef bootstrap (using the SSH protocol). The goal of the bootstrap is to get Chef installed on the target system so it can run Chef Client with a Chef Server. The main assumption is a baseline OS installation exists (provided by the provisioning). It is primarily intended for Chef Client systems that talk to a Chef server. By default the server is bootstrapped using the ubuntu10.04-gems template. This can be overridden using the -d or --template-file command options.

Deletes an existing server in the currently configured Linode account. PLEASE NOTE - this does not delete the associated node and client objects from the Chef server.

Outputs a list of all servers in the currently configured Linode account. PLEASE NOTE - this shows all instances associated with the account, some of which may not be currently managed by the Chef server.
