CloudInit logs

[cristian98149]

Hi,
is there a way to view logs about errors encauntered during cloud-init execution?

For example, if a something in cloud-init file (for example a command) fails, how can we get logs about this?

Thank you

Hi!

on version lower than 2.0.0, the "cloud-init" stages execution is done via systemd services so you should be able to gather their logs with a simple journalctl -u cos-setup-STAGE

The service names are as follows:

cos-setup-rootfs
cos-setup-initramfs
cos-setup-network
cos-setup-boot
cos-setup-fs
cos-setup-reconcile

For versions higher or equal to 2.0.0, the rootfs and initramfs stages are now run via immucore and that stores the rootfs and initramfs logs to the /run/immucore dir.

It also allows you to enable debug mode for the runs by settings rd.immucore.debug in the cmdline
