Client library for Rackspace's Cloud Servers API
This is a client for Rackspace’s Cloud Servers API. There’s a Python API (the cloudservers module), and a command-line script (cloudservers). Each implements 100% of the Rackspace API.
You’ll also probably want to read Rackspace’s API guide (PDF) – the first bit, at least – to get an idea of the concepts. Rackspace is doing the cloud hosting thing a bit differently from Amazon, and if you get the concepts this library should make more sense.
Development takes place on GitHub. Bug reports and patches may be filed there.
Installing this package gets you a shell command, cloudservers, that you can use to interact with Rackspace.
You’ll need to provide your Rackspace username and API key. You can do this with the --username and --apikey params, but it’s easier to just set them as environment variables:
export CLOUD_SERVERS_USERNAME=jacobian export CLOUD_SERVERS_API_KEY=yadayada
You’ll find complete documentation on the shell by running cloudservers help:
usage: cloudservers [--username USERNAME] [--apikey APIKEY] <subcommand> ... Command-line interface to the Cloud Servers API. Positional arguments: <subcommand> backup-schedule Show or edit the backup schedule for a server. backup-schedule-delete Delete the backup schedule for a server. boot Boot a new server. delete Immediately shut down and delete a server. flavor-list Print a list of available 'flavors' (sizes of servers). help Display help about this program or one of its subcommands. image-create Create a new image by taking a snapshot of a running server. image-delete Delete an image. image-list Print a list of available images to boot from. ip-share Share an IP address from the given IP group onto a server. ip-unshare Stop sharing an given address with a server. ipgroup-create Create a new IP group. ipgroup-delete Delete an IP group. ipgroup-list Show IP groups. ipgroup-show Show details about a particular IP group. list List active servers. reboot Reboot a server. rebuild Shutdown, re-image, and re-boot a server. rename Rename a server. resize Resize a server. resize-confirm Confirm a previous resize. resize-revert Revert a previous resize (and return to the previous VM). root-password Change the root password for a server. show Show details about the given server. Optional arguments: --username USERNAME Defaults to env[CLOUD_SERVERS_USERNAME]. --apikey APIKEY Defaults to env[CLOUD_SERVERS_API_KEY]. See "cloudservers help COMMAND" for help on a specific command.
There’s also a complete Python API.
By way of a quick-start:
>>> import cloudservers >>> cs = cloudservers.CloudServers(USERNAME, API_KEY) >>> cs.flavors.list() [...] >>> cs.servers.list() [...] >>> s = cs.servers.create(image=2, flavor=1, name='myserver') ... time passes ... >>> s.reboot() ... time passes ... >>> s.delete()
What’s wrong with libcloud?
Nothing! However, as a cross-service binding it’s by definition lowest common denominator; I needed access to the Rackspace-specific APIs (shared IP groups, image snapshots, resizing, etc.). I also wanted a command-line utility.
