As finding the answer to this question has proven somewhat complicated, I’ll note my approach here for future reference (excerpt): Basically, copy pem (Base64 encoded) versions of your CA trust chain into /var/lib/boot2docker/certs/. You can’t use… Continue Reading Docker – Add trusted root ca to local docker-machine swarm
