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.
