Build and deploy a FDU on a node?

[zrnapoleon]

For now, I have successfully installed the fog with its 5 plugins. But when i tried to deploy a LXD FDU:
$ python3 lifecycle_non_lxd_test.py 127.0.0.1:7887 fdu_lxd_test.json
Here lifecycle_non_lxd_test.py and fdu_lxd_test.json are based on:
https://github.com/atolab/fog05_demo/blob/master/fim_api/lifecycle_nonetwork.py
and
https://github.com/atolab/fog05_demo/blob/master/fim_api/fdu_lxd.json
with mu node ID:

and the net interface:

I got the following error:

Hope you can give me some help, thanks!

Hi @zrnapoleon, can you please paste the output of the LXD plugin?

This seems related to some permission issue to the user that is running the LXD plugin, to I guess we can get more information from that log

[zrnapoleon]

Hi @gabrik , the output of LXD plugin:

I see, this is some strange permisison error coming from LXD APIs.

Try to run this:

$ sudo -u fos python3
> from pylxd import Client
> c = Client()
> c.profiles.create('test') 

You should get the same error, can you confirm?

[zrnapoleon]

I did, but got a conection error when I rename the c = Client() before passing the test:

Ok, I still think LXD as some strange configuration.

Try this:

$ sudo -u fos python3
> from pylxd import Client
> c = Client(endpoint='https://127.0.0.1:8443', verify=False)
> c.profiles.create('test') 

And you should get the same unauthorized error

[zrnapoleon]

Yeah, it is, It return the same error : nor authorized

[gabrik]

Ok, can you paste the output of:

$ sudo -u fos groups

On our test machine it returns fos sudo lxd, you should get the same

[zrnapoleon]

Yeah , it is:
ubuntu@chenyanjun-3:~/fog05_demo/fim_api$ sudo -u fos groups
fos sudo lxd

[gabrik]

After some investigation, this can be related to canonical/pylxd#365, so you can try to add this environment variable in a system-wide manner:

echo "export LXD_DIR=/var/snap/lxd/common/lxd" >> /etc/environment/

Edit: you may need to reboot
