I've got a new server spun up with Ubuntu Server and LXC installed for apt. I've been reading the docs and trying to understand how to import images/templates. I'm having a hard time understanding how to import a list of public images and specifically how to setup a new instance with Alpine. I believe this can be done with a tarball of the ISO (from the man page) but there's also a remote option.
The LXC container list here: https://us.images.linuxcontainers.org/ says these are available via lxc-download template which I assumed was a command to trigger a template but now I'm just more confused.
