cloud-init-datasources

Configures cloud-init to only use an explicit list of data sources.

Cloud-init contains a growing collection of data source modules and most are enabled by default. This causes cloud-init to query each data source on first boot. This can cause delays or even boot problems depending on your environment.

Including this element without setting DIB_CLOUD_INIT_DATASOURCES will cause image builds to fail.

Environment Variables

DIB_CLOUD_INIT_DATASOURCES

Required:

Yes

Default:

None

Description:

A comma-separated list of valid data sources to limit the data sources that will be queried for metadata on first boot.

Example:

DIB_CLOUD_INIT_DATASOURCES="Ec2" will enable only the Ec2 data source.

Example:

DIB_CLOUD_INIT_DATASOURCES="Ec2, ConfigDrive, OpenStack" will enable the Ec2, ConfigDrive and OpenStack data sources.

Warning

Use of the ConfigDrive data source is only considered, by default, for initial network configuration per cloud-init documentation. It is recommended that you utilize OpenStack in addition to ConfigDrive to collect all available metadata and configuration. As a result of configuration drive use, cloud-init’s automatic metadata discovery network activation is disabled.
