for container in `lxc list mysql-rep --format=json | jq .[].name | tr -d
'"'`; do lxc exec $container -- apt update; done

Thanks, Stéphane, i'm very inattentive... Now it looks better.
Additional output format seems to be more comfortable than additional

And what do you think about the second question about ability to run

container name ? Is this feature looks useful?
