/var/lib/cloud has the following structure:
- scripts/
per-instance/
per-boot/
per-once/
files in these directories will be run by 'run-parts' once per
instance, once per boot, and once per *ever*.
- seed/
<datasource>/
sys-user-data
user-data
meta-data
The 'seed/' directory allows you to seed a specific datasource
For example, to seed the 'nocloud' datasource you would need to
populate
seed/nocloud/user-data
seed/nocloud/meta-data
- instance -> instances/i-abcde
This is a symlink to the current instance/<instance-id> directory
created/updated on boot
- instances/
i-abcdefgh/
scripts/ # all scripts in scripts are per-instance
sem/
config-puppet
config-ssh
set-hostname
cloud-config.txt
user-data.txt
user-data.txt.i
obj.pkl
handlers/
data/ # just a per-instance data location to be used
boot-finished
# this file indicates when "boot" is finished
# it is created by the 'final_message' cloud-config
datasource # a file containing the class and string of datasource
- sem/
scripts.once
These are the cloud-specific semaphores. The only thing that
would go here are files to mark that a "per-once" script
has run.
- handlers/
"persistent" handlers (not per-instance). Same as handlers
from user-data, just will be cross-instance id
- data/
this is a persistent data location. cloud-init won't really
use it, but something else (a handler or script could)
previous-datasource
previous-instance-id
previous-hostname
to clear out the current instance's data as if to force a "new run" on reboot
do:
( cd /var/lib/cloud/instance && sudo rm -Rf * )
