docker-machine-hypriot 0.4.1 findings about image-builder-rpi

[StefanScherer]

Using the latest docker-machine v0.6.0-rc2 binary also works "out-of-the-box" with some additional options:

docker-machine -D create -d generic --generic-ip-address 192.168.10.23 --generic-ssh-user pirate --engine-storage-driver overlay hypriotos

Creating a swarm probably needs the --swarm-image hypriot/rpi-swarm:latest, but I haven't tried it yet.

Ping @benediktarnold :-)

@jottr No problem 😃

OK, for the 0.6/0.7 HypriotOS images based on Raspbian you have to prepare the OS a little bit to work with standard docker-machine binary. Have a look at the blog post http://blog.hypriot.com/post/how-to-setup-rpi-docker-swarm/ beginning with Prepare your Pi’s for docker-machine.

In /etc/os-release the string raspbian must be changed to debian.

[StefanScherer]

Oh, there's another interesting option: --engine-install-url "https://get.docker.com"

So we could have a workaround with something like --engine-install-url "https://get.hypriot.com" 😄

Hopefully I'm not spamming:
If I read @StefanScherer post correctly, using the official docker-machine binary from 0.6.0-rc2 should be working out of the box.
I've tried with 0.6.0, build e27fb87 and 0.7.0-rc1:

@jottr The new SD image does not have a SSH login for root, only user pirate. You have to specify --generic-ssh-user pirate as well.

[jottr]

@StefanScherer so it seems I did indeed hijack this issue. I'm using the 0.7.0 Berry (beta) avalailable on the download page. Sorry for that.

The pirate user is not available. After copying my ssh key, I am able to ssh on to the pi as a root user.
Trying to to the same thing with

docker-machine -D create -d generic \
--generic-ip-address 192.168.2.134 \
--generic-ssh-user root \
--engine-storage-driver overlay rpi

results in the following error:
