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.
Full documentation is available.
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.
Contents:
Installing this package gets you a shell command, cloudservers
, that you
can use to interact with any Rackspace compatible API (including OpenStack).
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
If you are using OpenStack or another Rackspace compatible API, you can
optionally define its authentication url with --url
. Or set it as
an environment variable as well:
export CLOUD_SERVERS_URL=http://myserver:port/v1.0/
You'll find complete documentation on the shell by running
cloudservers help
:
usage: cloudservers [--username USERNAME] [--apikey APIKEY] [--url AUTH_URL] <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]. --url AUTH_URL Defaults to env[CLOUD_SERVERS_URL] or https://auth.api.rackspacecloud.com/v1.0 if undefined. 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 [, AUTH_URL]) >>> 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.
