Overview
- Where is the local registry stored?
- What is "the disk image"?

Installation and Uninstallation
Configuration
Docker Buildkit
Docker 19.03.13 comes with Docker buildkit enabled and that causes problems while building image - an image build fails if a base image is not cached. To disable it:
1. Set DOCKER_BUILDKIT=0
export DOCKER_BUILDKIT=0
or
2. Preferences → Docker Engine → edit "buildkit": false → Apply and Restart.

Local Volume Location
The docker volume inspect command reports the local volume mountpoint as:
/var/lib/docker/volumes/localenv_psqlvol/_data
However, that path is relative to the Docker VM
Docker Desktop File Sharing
To expose local directories as "hostPaths" in pods deployed on Docker Desktop Kubernetes, those directories must exist under the "shared directories" declared in Preferences → Resources → File Sharing. As a special case, if we want to share files under the Mac's host /tmp, the hostPath should be /private/tmp/[...].
