Datasources¶
Datasources are sources of configuration data for cloud-init that typically
come from the user (i.e., user-data) or come from the cloud that created the
configuration drive (i.e., meta-data). Typical user-data includes files,
YAML, and shell scripts whereas typical meta-data includes server name,
instance id, display name, and other cloud specific details.
Any meta-data processed by cloud-init’s datasources can be inspected. See
Instance-data for more information.
How to configure which datasource to use¶
In most cases, users of cloud-init should not have to configure
cloud-init to specify which datasource cloud-init is running on;
cloud-init should be able to identify the platform.
There are exceptions, however, when the datasource does not
identify itself to cloud-init. In this case, the
datasource detection may be overridden by configuring a single datasource
in the datasource_list
or by using kernel command line arguments.
