Thx @valentin69 for your feedback.

did you run eval "$(docker-machine env machine1)" from the MacOSX Host ?

[valentin69]

Absolutely :
$ env | grep DOCKER
DOCKER_HOST=tcp://192.168.99.101:2376
DOCKER_MACHINE_NAME=machine1
DOCKER_TLS_VERIFY=1
DOCKER_CERT_PATH=/Users/valentin/.docker/machine/machines/machine1

[jeanlaurent]

From your 1st message it sounds like machine1 ip is 192.168.99.100 and from your 2nd message your DOCKER_HOST is 192.168.99.101. I don't have all the details of what you did but it sounds like your need to refresh you env and/or recreate your machine.

[valentin69]

That is just because I destroyed the machine and recreated a new one (in my various attempts to find what's going wrong...).
machine1 * virtualbox Running tcp://192.168.99.101:2376
DOCKER_HOST=tcp://192.168.99.101:2376

The problem is still there :
$ docker images
An error occurred trying to connect: Get https://192.168.99.101:2376/v1.21/images/json: Service Unavailable

[jeanlaurent]

This is really weird.

Sounds like the machine is setup but maybe the docker daemon may not run.

can you check if the daemon is running by docker-machine ssh default and type in ps aux | grep 'docker daemon and report here the result ?

Although if it was the case, the docker-machine env default should report the problem beforehand.

What's your docker version ?

Nice to have seen each other in f2f @ dockercon

[valentin69]

Hi Jean Laurent,
Yes it was very nice seeing you at the Dockercon EU 15.
I ended up destroying the machines, cleanind ~/.docker/machine and installing the next version of the toolbox that was released just before Dockercon and it is working now.
Cleaning up the cache probably did the trick.

I had a similar problem on Windows (Docker Toolbox 1.10.3), but it was due to my proxy configuration.
I solved my problem with this : https://docs.docker.com/machine/reference/env/#excluding-the-created-machine-from-proxies
(adding NO_PROXY env variable).
