Docker Desktop for Mac OSCatalina Mount SD Card Volume in Container as loop device to flash SD Card with dd
I think this will work:
docker run -v /dev:/dev --privileged YOURIMAGE bashthen :
dd if=/dev/random of=/dev/disks2you need also to share /dev in your docker configurations , and I think it is some how risky to share it beside using the --privileged parameters .....
you will get the following message if you do not share /dev:
docker: Error response from daemon: Mounts denied:The path /dev/disk1s2is not shared from OS X and is not known to Docker.You can configure shared paths from Docker -> Preferences... -> File Sharing.See https://docs.docker.com/docker-for-mac/osxfs/#namespaces for more info.
