Add global lxd remote image server

LXD
1

Simple really: Is there any way to add a lxd remote server that is known to every user on a given lxd host? As far as I understand “lxc remote” needs to be executed for every user on the system that gets to use lxd. It would be very handy if I could provision remote lxd image servers per host together with the lxd instance itself instead of per user.

I can think of a few ways of doing that.

  1. Have a common account for working with LXD, and give users ssh access to it.
  2. Copy your $HOME/snap/lxd/current/.config/lxc somewhere where everyone has read access, and have everyone symlink their own $HOME/snap/lxd/current/.config/lxc to that.
  3. Create a container for managing LXD with a common account that users have ssh access to. The container can manage LXD simply by copying a working config in $HOME/snap/lxd/current/.config. It’s easier to just use https instead of unix sockets, but you can also proxy a unix socket if you want. This is a variation of 1 + 2.
  4. Give each user their own container, which has snap/lxd installed and attach a common LXD volume for all at the path $HOME/snap/lxd/…’

I have used 1 and 3 (just for myself).

$HOME/ snap/lxd/current/.config/lxc/config.yml don’t seems to contain remote definition

My remote:

 # lxc remote list
+-----------------+------------------------------------------+---------------+-------------+--------+--------+--------+
|      NAME       |                   URL                    |   PROTOCOL    |  AUTH TYPE  | PUBLIC | STATIC | GLOBAL |
+-----------------+------------------------------------------+---------------+-------------+--------+--------+--------+
| images          | https://images.linuxcontainers.org       | simplestreams | none        | YES    | NO     | NO     |
+-----------------+------------------------------------------+---------------+-------------+--------+--------+--------+
| my-remote       | https://xxx.yyy.fr:8443                  | lxd           | tls         | NO     | NO     | NO     |

And my config file:

# cat snap/lxd/current/.config/lxc/config.yml
default-remote: local
remotes:
  images:
    addr: https://images.linuxcontainers.org
    protocol: simplestreams
    public: true
  local:
    addr: unix://
    public: false
aliases: {}
