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 a network adapter is NOT a requirement. See server context in their 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 can 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 having 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 the value. If this field does not exist, the default value is “net”.
