How to export Docker-machine configuration to be used on other machines

Question

What's the best way to move docker-machine machines (remote not local host) from one computer to another (osx to windows). I have to change the config.json files for all the machines so it works on another computer, because the path to the certs and machine are all hardcoded in the config file.

while this approach works, it's a bit tedious if we need to share them with everyone on the team. Is there a way to export or import the machine? or there are other ways to archive what I am trying to do.

Until this feature gets implemented natively (see Issue 23), you can use this import/export script I've written.

Export (on host A)

$ docker-machine ls
NAME       ACTIVE   DRIVER         STATE     URL                            SWARM   DOCKER    ERRORS
dev        -        digitalocean   Running   tcp://example.com:2376                 v1.10.1

$ ./docker-machine-export.sh dev
Exported machine to dev.zip

$ ls
docker-machine-import.sh
docker-machine-export.sh
dev.zip

Import (on host B)

$ docker-machine ls
NAME       ACTIVE   DRIVER         STATE     URL                            SWARM   DOCKER    ERRORS

$ ./docker-machine-import.sh dev.zip
Exported machine to dev.zip

$ docker-machine ls
NAME       ACTIVE   DRIVER         STATE     URL                            SWARM   DOCKER    ERRORS
dev        -        digitalocean   Running   tcp://example.com:2376                 v1.10.1
