我想在我的虚拟集群上设置docker swarm。首先，我尝试使用docker-machine在localhost上安装swarm-master。
问题是机器需要使用代理来访问发现令牌。
首先我问一个带有swarm创建的令牌。为此，我创建了这个文件：
$docker run -e "http_proxy=http://**.**.**.**:3128/" -e "https_proxy=http://**.**.**.**:3128/" swarm create
b54d8665e72939d2c611d8f9e99521b4
我重启了守护进程，我可以拉出群组图像：
$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
我想创建swarm master：
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...
Setting Docker configuration on the remote daemon...
Configuring swarm...
To see how to connect Docker to this machine, run: docker-machine env swarm-master
结果：
$docker ps

我在加入和管理容器的日志中有错误（我认为错误是因为容器不处理代理）：

答案 0 :(得分：1)
问题在于，无法使用docker机器在同一台机器上创建swarm-master。所以我创建了两个VM，一个用docker-machine（和mh-keystore），另一个用于swarm-master。
在localhost上创建mh-keystore：
$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
将swarm-master安装到另一台机器
$ 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
创建代理人：
$ docker-machine create \
-d generic --generic-ip-address 192.168.2.102 \
--swarm \
--swarm-discovery="consul://192.168.2.103:8500" \
swarm-agent-00
