Scenarios
Cloud-init primarily allows you to customize configurations during the first initialization of an instance. If an imported image is not installed with the cloud-init service, the instance that is enabled based on this image cannot be initialized normally, causing a failure in the normal import of this image. This document describes how to install the cloud-init service. The following three methods are recommended for installing cloud-init:
By downloading the cloud-init binary package.
By manually downloading the cloud-init source package.
By using the cloud-init package from the software source.
