我使用Docker Overlay网络创建了一个Docker多主机网络，该网络有4个节点：node0，node1，node2和node3。 Node0充当键值存储，其共享节点的信息，而node1，node2和node3绑定到键值存储。 
 
  
 
 这是node1网络： 
 
user@node1$ docker network ls
NETWORK ID          NAME                DRIVER
04adb1ab4833        RED                 overlay             
 [ . . ]
 
 至于node2网络： 
 
user@node2$ docker network ls
NETWORK ID          NAME                DRIVER
04adb1ab4833        RED                 overlay             
 [ . . ]
 
 container1正在node1上运行，该节点承载着名为RED的网络。 
 
user@node1$ docker ps -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                    PORTS               NAMES
f9bacac3c01d        ubuntu              "/bin/bash"         3 hours ago         Up 2 hours                                    container1
 
 Docker为属于RED覆盖网络的每个容器的/ etc / hosts添加了一个条目。 
 
user@node1$ docker exec container1 cat /etc/hosts

10.10.10.2  d82c36bc2659
127.0.0.1   localhost
 [ . . ]
10.10.10.3  container2
10.10.10.3  container2.RED
 
 从node2，我正在尝试访问在node1上运行的container1。 我尝试使用下面的命令运行container1但它返回错误。 
 
`user@node2$ docker docker exec -i -t container1 bash`
Error response from daemon: no such id: container1
 
 有什么建议吗？ 
 
 谢谢。 

I have created a Docker multi-host network using Docker Overlay network with 4 nodes: node0, node1, node2, and node3. Node0 act as key-value store which shares the information of nodes while node1, node2, and node3 are bound to the key-value store. 
 
 
Here are node1 networks:
 
user@node1$ docker network ls
NETWORK ID          NAME                DRIVER
04adb1ab4833        RED                 overlay             
 [ . . ]
 
As for node2 networks:
 
user@node2$ docker network ls
NETWORK ID          NAME                DRIVER
04adb1ab4833        RED                 overlay             
 [ . . ]
 
container1 is running on node1, that hosts the RED-named network.
 
user@node1$ docker ps -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                    PORTS               NAMES
f9bacac3c01d        ubuntu              "/bin/bash"         3 hours ago         Up 2 hours                                    container1
 
Docker added an entry to /etc/hosts for each container that belongs to the RED overlay network.
 
user@node1$ docker exec container1 cat /etc/hosts

10.10.10.2  d82c36bc2659
127.0.0.1   localhost
 [ . . ]
10.10.10.3  container2
10.10.10.3  container2.RED
 
From node2, I'm trying to access the container1 running on node1. I tried to run container1 using command below but it returns error. 
 
`user@node2$ docker docker exec -i -t container1 bash`
Error response from daemon: no such id: container1
 
Any suggestion?
 
Thanks.
