FAQ

autoinstall

Other projects, such as Subiquity autoinstaller, use cloud-init to implement a subset of their features and have a YAML configuration format which combines cloud-init’s cloud-config with additional keys.

If you are an autoinstall user, please direct questions to their IRC channel (#ubuntu-server on Libera).

Can I use cloud-init as a library?

Please don’t. Some projects do. However, cloud-init does not currently make any API guarantees to either external consumers or out-of-tree datasources / modules. Current users of cloud-init as a library are projects that have close contact with cloud-init, which is why this (fragile) model currently works.

For those that choose to ignore this advice, logging in cloud-init is configured in cloud-init/cmd/main.py, and reconfigured in the cc_rsyslog module for obvious reasons.
