IIRC, you can't add EBS or EFS volumes to Fargate tasks, and with EBS volumes you don't have concurrent access between multiple build runners. You can attach EFS to fargate tasks. My more general point there was that it feels like a lot of complexity disappears if you don't have an ephemeral build service and can just use docker as docker. Something I'd missed in my first readthrough was about using existing running containers - that makes me a little uneasy but "start from scratch" and "update a running system" are fair points to find tradeoffs between them. It all feels like trying to push the tools to work in a way they weren't really intended to.
