Variables in profile?

[RandomUser]

Hi, is it possible to have variables in an LXD profile to be set from command line during lxc launch?

I don’t believe this is possible I’m afraid.

I have an idea for a workaround I suppose: defining a temporary profile, launching lxd launch and deleting that temporary profile afterwards. Do you see any disadvantages of that concept?

If you’re looking to apply specific overrides to individual instances, why don’t you just override them when you create the instance?

What are you looking to change?

I think you’re post is related to another thread, and this example here is effectively doing a per-instance override like I mentioned above:

Cloud-init on Alpine - how to use it?

Humm, if you can produce the yaml file then everything is possible. A simple example. indiana@mars:~$ more test.yaml #cloud-config users: - default - name: foo gecos: Foo indiana@mars:~$ lxc launch images:alpine/edge/cloud --config=user.user-data="$(cat test.yaml)" Creating the instance Instance name is: inspired-whale Starting inspired-whale indiana@mars:~$ lxc exec inspired-whale – getent passwd | grep -i foo foo:x:1000:1000:Foo:/home/foo:/bin/ash
