|
\fBcloud-init\fR
|
|
has two services: cloud-init-firstboot and cloud-init.
|
|
cloud-init-fistboot service runs during first boot of a new cloud intance,
|
|
with the purpose of configuring the cloud instance for use of the end user.
|
|
cloud-init service runs in each boot after first boot, with the purpose of
|
|
maintaining the cloud instance in a right state (resize/fix partitions and/or
|
|
filesystems, reprocess user data and/or metadata, and more).
|
|
.PP
|
|
Various tasks can be performed, and all are optional. cloud-init can create
|
|
user accounts, user groups, register ssh keys, write content to files,
|
|
perform software update or install new software, and more.
