Or you could run Caddy which had a built in ACME client, but then you're running an extra daemon.

apache_mod_md eventually came along which works for me, but it's also got some lazy things (it mostly just manages requesting certs, you've got to have a frequent enough reload to pick them up; I guess that's ok because I don't think public Apache ever learned to periodically check if it needs to reopen access logs when they're rotated, so you probably reload Apache from time to time anyway)

Before that was workable, I did need some certs and used acme.sh by hand, and it was nicer than trusting a big thing running in a cron and restarting things, but it was also inconvenient becsause I had to remember to go do it.
