2022-03-17 21:23:00 UTC - Jacqueline Bruen: "Custom runtime images will be pulled from Docker Hub into the local platform registry upon the first invocation. This can lead to longer cold-start times on the first invocation with a new or updated image. Once images have been pulled down, they are cached locally." QUESTION: Where are these cached locally? I don't see the images when I do "docker image ls"

2022-03-17 21:29:39 UTC - Matt Welke: My understanding is that this is describing using Kubernetes as the platform upon which you deploy OpenWhisk, and that therefore the default behavior of Kubernetes is taken advantage of here, where the cluster nodes each contain a cache of pulled images. So OpenWhisk is relying on that behavior and counting on those caches to be hit.

I am just trying the locate the directory where these images are cached because "docker image ls" isn't picking them up.
