Docker-Machine and Swarm behind proxy - proxy

Question

I'm traing to set up docker swarm over my virtual cluster. First, I try to install the swarm-master on the localhost with docker-machine.
The problem is that the machine need to use a proxy to access the discovery token.
First I ask a token with swarm create. To do that, I created this file :
$cat /etc/systemd/system/docker.service.d/http_proxy.conf
[Service]
Environment="HTTP_PROXY=http://**.**.**.**:3128/" "HTTPS_PROXY=http://**.**.**.**:3128/" "NO_PROXY=localhost,127.0.0.1,192.168.2.100,192.168.2.101,192.168.2.102,192.168.2.103,192.168.2.104,192.168.2.105,192.168.2.106,192.168.2.107,192.168.2.108,192.168.2.194,192.168.2.110"
I restarted the daemon and I can pull the swarm image :
$docker run -e "http_proxy=http://**.**.**.**:3128/" -e "https_proxy=http://**.**.**.**:3128/" swarm create
b54d8665e72939d2c611d8f9e99521b4
After I want to create the swarm master :
$docker-machine create -d generic --generic-ip-address localhost \
--engine-env HTTP_PROXY=http://192.168.254.10:3128/ \
--engine-env HTTPS_PROXY=http://192.168.254.10:3128/ \
--engine-env NO_PROXY=localhost,192.168.2.102,192.168.2.100 \
--swarm --swarm-master --swarm-discovery \
token://b54d8665e72939d2c611d8f9e99521b4 swarm-master
Result :
Running pre-create checks...
Creating machine...
Waiting for machine to be running, this may take a few minutes...
Machine is running, waiting for SSH to be available...
Detecting operating system of created instance...
Provisioning created instance...
Copying certs to the local machine directory...
Copying certs to the remote machine...

Configuring swarm...
To see how to connect Docker to this machine, run: docker-machine env swarm-master
And I have errors in the logs of the join and manage container (I think the error come because the containers don't take care of the proxy) :
$docker ps

Is it a bug of the generic driver ?

Thank you :)

Answer 1

The problem was that it's not possible to use docker machine to create the swarm-master on the same machine. So I created two VM, one with docker-machine (and mh-keystore) and one other for swarm-master.
Creating the mh-keystore on localhost :
$docker-machine create -d generic --generic-ip-address localhost mh-keystore
$docker $(docker-machine config mh-keystore) run -d \
-p "8500:8500" \
-h "consul" \
progrium/consul -server -bootstrap
$docker ps
Installation of swarm-master to the other machine
$ docker-machine create \
-d generic --generic-ip-address 192.168.2.100 \
--swarm --swarm-image="swarm" --swarm-master \
--swarm-discovery="consul://192.168.2.103:8500" \
swarm-master
Creation of agent :
$ docker-machine create \
-d generic --generic-ip-address 192.168.2.102 \
--swarm \
--swarm-discovery="consul://192.168.2.103:8500" \
swarm-agent-00
