.. _datasource_cloudstack:
CloudStack
==========
`Apache CloudStack`_ expose user-data, meta-data, user password and account
sshkey thru the Virtual-Router. The datasource obtains the VR address via
dhcp lease information given to the instance.
For more details on meta-data and user-data,
refer the `CloudStack Administrator Guide`_.
URLs to access user-data and meta-data from the Virtual Machine. Here 10.1.1.1
is the Virtual Router IP:
.. code:: bash
http://10.1.1.1/latest/user-data
http://10.1.1.1/latest/meta-data
http://10.1.1.1/latest/meta-data/{metadata type}
Configuration
-------------
The following configuration can be set for the datasource in system
configuration (in `/etc/cloud/cloud.cfg` or `/etc/cloud/cloud.cfg.d/`).
The settings that may be configured are:
* **max_wait**: the maximum amount of clock time in seconds that should be
spent searching metadata_urls. A value less than zero will result in only
one request being made, to the first in the list. (default: 120)
* **timeout**: the timeout value provided to urlopen for each individual http
request. This is used both when selecting a metadata_url and when crawling
the metadata service. (default: 50)
An example configuration with the default values is provided below:
.. sourcecode:: yaml
datasource:
CloudStack:
max_wait: 120
timeout: 50
datasource_list:
