hi,
I created dind-machine, a simple wrapper for docker-machine, since I love docker-machine's simplicity but also experienced some drawbacks. It's a pain sharing your docker-machine setup with others! The configuration files works only on a specific machine due to the usage of absolute paths. So just sharing the docker-machine folder ~/.docker does not do the trick. You still need to adapt your configuration to the new environment. dind-machine simply moves docker-machine into docker and uses a docker volume for persistence. So you get both: absolute paths inside the container (/root/.docker) and any path you wish on the host. Another nice property of this solution: you do not need install docker-machine locally, you just pull the nukapi/dind-machine docker image.
What do you think about this?
