docker-machine support is broken for 0.5.0

[lukaso]

Fails in 2 ways:

1. Does not detect that docker-machine is already running, and stops loading with Machine "xxx" is already running.

2. Is unable to find the ssh key because the correct inspect command should be:

docker-machine inspect --format="{{.HostOptions.AuthOptions.StorePath}}" "$DOCKER_MACHINE_NAME"

instead of:

docker-machine inspect --format="{{.StorePath}}" "$DOCKER_MACHINE_NAME"

which returns <no value>.

Are you interested in submitting a PR for these? :)

[lukaso]

Yes, though I don't know if it's version specific. So I can do a PR to cover the exact failures I'm seeing.

@lukaso I just upgraded yesterday, I'll try to reproduce your issue and patch it, because this is very likely to become a blocker for me then. Unless you manage to send PR before me that is :)

Here is the pull request #134. It is working for me.

Have you noticed keys being moved?

Here is my set up, it might be out of date now:

❯❯❯ docker-machine inspect --format="{{.HostOptions.AuthOptions.StorePath}}" dev                                                             master
/Users/jacob/.docker/machine
❯❯❯ find /Users/jacob/.docker/machine/ -name 'id_*'                                                                                        elastic_test
/Users/jacob/.docker/machine//machines/dev/id_rsa
/Users/jacob/.docker/machine//machines/dev/id_rsa.pub

So for my setup I would require:

  DOCKER_HOST_SSH_KEY="$DOCKER_MACHINE_STORE_PATH/machines/$DOCKER_MACHINE_NAME/id_rsa"

Fixed in #136.
