Running Docker container with --privileged flag after OS reboot?

Question

Docker

Good afternoon colleagues, tell me after starting the container with the --privileged flag, the container receives the necessary privileges and works, in particular, it deletes and creates rules with iptables, the container with fail2ban,
but after restarting the OS, the container starts successfully, but already apparently without this flag, as a result, the necessary melted in Iptables do not get and fail2ban does not work out the blocking rules
Who solved this problem if it is solvable?
And the second question, in the default RancherOS console, the time zone is set to UTC, how to change it without resorting to changing the type of the console itself to debian centos, etc.
