> it's not so scary when it's something you do so frequently
Yeah, I've found this to be the trick for ongoing hassle-free maintenance too. Make tearing stuff down and up frequent enough and you'll feel confident and safe when you're required to do so to recover from something.
Scariest are applications/services/servers that has been running for years but never restarted nor ever restored. Those scare me.
Cattle, not kittens. My favorite thing about deploying containerized apps? They’re completely fungible and I never have to care about an individual instance. Oh, it hung due to some weird network interaction? Spawn a new one, then come back to see what went wrong with this one before you kill it.
