I don't run Redis, or anything else that has data storage, in a containerized environment. Those are dedicated machines to a dedicated purpose and I already have resource slicing and prioritization in place. They're called "virtual machines".
You might be fully aware, but containers doesn't have to be docker/kubernetes. Previously OpenVZ, and now LXC/LXD is great for replacing full VMs in a lot of scenarios. The isolation is great and it's way less resource intensive than full containers.
Quite aware, though others probably aren’t so it’s worth mentioning. But in my case, I press a button and I get an AWS or DigitalOcean or GCP instance.
I like containers for my stuff. It’s silly, IMO, to doubly encapsulate my datastores.
