AWS ECS Memory Definition

Question

Is Memory for hard and soft limits for tasks in terms of RAM or is it in terms of storage memory? Mainly, does a docker volume that I attach to a container take up this memory?

Answer 1

No. Attached volumes are a straight read from the host disk, nothing to do with provisioned memory. tmpfs mounts are an exception, as they write to memory: https://docs.docker.com/storage/tmpfs/
