Hi Mohamed

Beware users have to put their *public* key in .ssh/authorized_keys

It's not possible to upload ssh keys at the momment via the API. The use
case is understandable but it's not sure if the API should cover every
possible case of  container configuration ( though patches welcome !)

Note it might be also to do this 'pct exec' which allows the host to
execute commands directly in the container
for instance

pct exec 142 cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 8 (jessie)"
NAME="Debian GNU/Linux"
VERSION="8 (jessie)"

You could try to script around this.
