Equivalent of (Debian packages) unattended-upgrades, needrestart ?

I'm considering using Alpine Linux for a couple of network servers that could really use extra hardening. They currently run Debian, which provides handy packages called 'unattended-upgrades' and 'needrestart' that, together, automate the process of downloading and installing security updates and restarting daemons (or rebooting the entire system) as necessary. I am reluctant to give up this automation, considering just how often remotely exploitable bugs have popped up in the past couple years -- Alpine avoids some of them, but I'd still be stuck with a dependency on OpenSSL, and the network services themselves need patching a little too often for me to be comfortable remembering to do it by hand.

Does Alpine have any equivalent? If so, what is it called? I haven't had any luck searching either the documentation or the package index.

(Yes, I could write a shell script and run it from cron, but I'd prefer something that has already been debugged.)
