There must be something wrong with the OSX implementation then? Container images should be static and won't be duplicated across multiple instances. Maybe I'm wrong about how it should work. My impression was that if I had a 1 GiB image, I could spin up 50 of these, and still use roughly 1 GiB of memory (assuming running process es don't need to allocate much themselves).

Edit: From testing by spinning up 10 MySQL servers, sure looks to be the case. Each runtime allocated approx 215 MiB of memory, which is what the available system memory was reduced by for each. The container image itself was approx 400 MiB.
