18.3.6. Automating the Initial Configuration of Cloud Instances Using cloud-init

- set the default locale
- configure the host name
- configure network interfaces
- generate private SSH keys
- add SSH keys to the user's
.ssh/authorized_keysdirectory - set up ephemeral mount points
Cloud-init is used with Red Hat's cloud products. See documentation on using cloud-init with Red Hat products:
