Hello,
I am getting an error in one of my projects, creating an lxd profile from a templated cloud-init (user-data) file. I am on ubuntu 20.04, with lxd 4.0.9 for reference.
Here is the error:
2022-11-17 01:57:19,902 - util.py[WARNING]: Failed loading yaml blob. Invalid format at line 2 column 1: "while parsing a block mapping
in "<unicode string>", line 2, column 1:
users:
^
expected <block end>, but found '<block mapping start>'
in "<unicode string>", line 18, column 5:
repo_update: true
^"
2022-11-17 01:57:19,903 - cloud_config.py[WARNING]: Failed at merging in cloud config part from part-001: empty cloud config
If I use the cloud-init.cfg files separate, they work fine, just seems to be an issue on my syntax perhaps? I have checked my indentation on a few rounds with the cloud-init config files.
Here is the cloud-init cfg file that I import to lxd profile.
## template: jinja

When I remove the lines at “repo_update…” and below, the config applies fine.
I am adding these cfg files to the lxd profile with:
lxc profile set profilename user.user-data - < cloud-init.cfg
Is there some special formatting we need when using jinja2 templating? I don’t understand why the same formatting works fine in a different profile without the jinja strings. Maybe my syntax is wrong, but when I was only adding the user accounts, all profiles worked fine across all my projects. It’s when I added the package directives it started giving errors in /var/log/cloud-init.log. Can share the logs if it will help.
Thank you, hoping someone has run into this, and can school me on my ignorance.
