I didn’t myself, but talked to a colleague recently who set it up for our company. Apparently it was quite tricky to get the various containers set up just right, as they need to communicate with each other but also be user facing and have proper certs and so on. I don’t have any details, but usually this guy is very good at deploying stuff, so if he admits to struggling I know it must be seriously hard.
I’ve been running my current setup with ZFS and ECC the last 10 years. With data archiving (don’t want to lose my kids‘ photos) ECC is important to me, as bit flips could otherwise break files even with ZFS.
