Docker-代理后面的机器和群
Docker-Machine and Swarm behind proxy
我正在训练在我的虚拟集群上设置 docker swarm。首先，我尝试使用 docker-machine.
在本地主机上安装 swarm-master
问题是机器需要使用代理来访问发现令牌。
首先我要一个带有 swarm create 的令牌。为此，我创建了这个文件：
$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"
我重启了守护进程，我可以拉取 swarm 镜像了：
$docker run -e "http_proxy=http://**.**.**.**:3128/" -e "https_proxy=http://**.**.**.**:3128/" swarm create
b54d8665e72939d2c611d8f9e99521b4
我想创建 swarm master 之后:
$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
结果：
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
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）：
$docker ps

是通用驱动程序的错误吗？

问题是无法使用 docker 机器在同一台机器上创建 swarm-master。所以我创建了两个 VM，一个带有 docker-machine（和 mh-keystore），另一个用于 swarm-master。
在本地主机上创建 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
安装swarm-master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：
$ docker-machine create \
-d generic --generic-ip-address 192.168.2.102 \
--swarm \
--swarm-discovery="consul://192.168.2.103:8500" \
