I am using the letsencrypt and the mariadb containers to host 19 websites (so far). I really appreciate the ease of use, and the automatic certificate renewal. Great work.
My concern is that I’ve placed all my eggs in the same basket, and if something goes wrong with a container upgrade, all the websites I host will go offline. They are mostly WordPress/WooCommerce websites, so there’s an actual cost involved if they’re not up and running.
I take daily backups of each website’s database, nginx configuration and of course all the files. But still, it would take me a lot of time to bring everything back up and running again.
How do you guys handle this kind of concern? Or I’m I being paranoid here? Is there a way to be more at ease when upgrading containers?
