=====================
CloudSigma Datasource
=====================

This datasource finds metadata and user-data from the `CloudSigma`_ cloud platform.
Data transfer occurs through a virtual serial port of the `CloudSigma`_'s VM and the
presence of network adapter is **NOT** a requirement,

  See `server context`_ in the public documentation for more information.


Setting a hostname
~~~~~~~~~~~~~~~~~~

By default the name of the server will be applied as a hostname on the first boot.


Providing user-data
~~~~~~~~~~~~~~~~~~~

You can provide user-data to the VM using the dedicated `meta field`_ in the `server context`_
``cloudinit-user-data``. By default *cloud-config* format is expected there and the ``#cloud-config``
header could be omitted. However since this is a raw-text field you could provide any of the valid
`config formats`_.

You have the option to encode your user-data using Base64. In order to do that you have to add the
``cloudinit-user-data`` field to the ``base64_fields``. The latter is a comma-separated field with
all the meta fields whit base64 encoded values.

If your user-data does not need an internet connection you can create a
`meta field`_ in the `server context`_ ``cloudinit-dsmode`` and set "local" as value.
If this field does not exist the default value is "net".
