Like mentioned above: you can use a container to copy from your host system into the Docker VM. This is how it worked for me: https://github.com/gesellix/inject-docker-certs
The linked project gives you:
- a simple script to generate CA and server certificates
- a docker image to perform the copy from your host into the VM
Interesting fact: I didn’t need to restart the Docker daemon anymore, so I’m not sure if that’s an improvement of the recently updated beta.
