Is it possible to use custom engine images instead of boot2docker when using “docker-machine create”? If yes, any directions about what expects docker-machine in that image so it gets properly configured? I’m using vmwarevsphere driver.
The only option that I’ve seen is using the generic driver.
Try specifying your custom image (an ISO) with the parameter
--vmwarevsphere-boot2docker-url. It doesn’t look like any checks are done to see if it’s actually a boot2docker image.
It looks like docker-machine first installs docker and some dependencies on the VM then inserts the SSH key into it and generates certificates.
Hope this helps!
