problem with creating new docker-machine

[ctrlok]

Hi. I have problem with creating new VM by scaleway docker-machine driver.

There is part of debug output:

(bench-2) DBG |   IMAGEID           FROM                                NAME                      ZONE                ARCH

(bench-2) DBG | - b5c5261e          bootscript:x86-64-4-10-8-docker-1   x86_64 4.10.8 docker #1                       x86_64
Error creating machine: Error in driver during machine creation: Too many candidates for docker (2)
notifying bugsnag: [Error creating machine: Error in driver during machine creation: Too many candidates for docker (2)]

There is output from "[GET]: https://cp-par1.scaleway.com/bootscripts":

I was tried to fix it by setting defaultBootscript variable to 8fd15f37-c176-49a4-9e1d-10eb912942ea (I found that ID here). But it fail with start docker on instance. There is output from journalctl:

-- Unit docker.service has begun starting up.
Apr 09 09:42:51 bench-2 docker[11354]: Command "daemon" is deprecated, and will be removed in Docker 17.12. Please run `dockerd` directly.

So, I try older bootscript cd65a9a3-b9db-4b3f-85a7-9aaa9e29d5da and it was fixed my problem, but I don't think it is a permanent solution.

Actually, the issue was not fixed. I still see that problem. And my PR was about removing IP, not creating instances.

Github closes this issue, @bchatelard can you check the public status of bootscripts ?

[bchatelard]

@QuentinPerez two docker bootscripts were available one 4.9.20 and one 4.10.8
@tbillon just removed the longterm (4.9.20).

Having two docker bootscripts available is valid for me, i believe the issue here is how the server is created.
The lookup of the bootscript is searching a booscript where the name is like .*docker.*.

Probably too late to answer but I had same issue as @QuentinPerez had. Using image ID fixes the issue, I believe it's linked with Scaleway service specifics.
