Installation and Uninstallation

Docker Mac Installation

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

https://docs.docker.com/docker-for-mac/#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/[...].

Also see:

hostPath on single-node Kubernetes Clusters (minikube, Docker_Desktop_Kubernetes)
