UpCloud
*******

The `UpCloud`_ datasource consumes information from UpCloud's `metadata
service`_. This metadata service serves information about the
running server via HTTP over the address ``169.254.169.254`` available in
every DHCP-configured interface. The metadata API endpoints are fully
described in `UpCloud API documentation`_.

Providing user data
===================

When creating a server, user data is provided by specifying it as
``user_data`` in the API or via the server creation tool in the control panel.
User data is immutable during the server's lifetime, and can be removed by
deleting the server.
