I’m running mine on Raspberry Pis as docker containers in a K8s cluster running in my home lab. Each Ghost instance has two pods, and I use an external HAProxy running on pfSense to point to the K8s Ingress. There’s a single pod running MariaDB that all the Ghost instances share. While that works, the performance can be a little sluggish, which is to be expected. I use AWS CloudFront as a public endpoint which takes care of the performance issue.
