[Janjaap Bos]

Perhaps you can even turn that into a bash alias.

Andriy, (meanwhile) you can help yourself with (doing that sequentially)..

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 tools. But it
insignificantly.

And what do you think about the second question about ability to run
commands on multiplie containers simultaneously using regexps as container
name ? Is this feature looks useful?
