NOTE: Most of the contents of this repository have been migrated to the new devcontainers GitHub org (https://github.com/devcontainers). See https://github.com/devcontainers/template-starter and https://github.com/devcontainers/feature-starter for information on creating your own!
I worked around this for now by adding this:
"initializeCommand": "docker volume rm dind-var-lib-docker-${devcontainerId}",
