For cloud-init with UC20, you have the following options:

  1. Put it in the root of your gadget snap as cloud.conf
  2. Put it in the ubuntu-seed partition at <ubuntu-seed>/data/etc/cloud/cloud.cfg.d/ with filenames ending with .cfg
  3. Provide through external filesystems that cloud-init will by default searches, for example the NoCloud datasource will search for drives labeled CIDATA with files in the root labeled meta-data and user-data
  4. Put it in ubuntu-seed, and let snapd filter out unsafe configuration from the config so only certain keys are allowed

Option 1 is always allowed with UC20, regardless of model assertion grade. Option 2 is only allowed with model assertion grade dangerous Option 3 is allowed only with model assertion grade dangerous and signed (so this does not work for secured). Option 4 is currently being worked on and will be allowed for model assertions grade signed and dangerous.

Here’s a table of allowed cloud-init methods vs the model assertion grade
