Question

我在单个节点上设置了Docker swarm，并在其上创建了一个运行nginx服务器的容器，但是我无法连接到指定端口上的nginx服务器。此外，我无法附加到容器。非常感谢任何帮助。

[user@hostname yum.repos.d]$ sudo docker swarm init
[user@hostname yum.repos.d]$ sudo docker info | grep -i "swarm: active"
Swarm: active
[user@hostname yum.repos.d]$
[user@hostname yum.repos.d]$ sudo docker node ls
ID                           HOSTNAME                      STATUS  AVAILABILITY  MANAGER STATUS

[user@hostname yum.repos.d]$ sudo docker service create --name web --publish 8080:80 nginx
[user@hostname ~]$ sudo docker ps -a
[sudo] password for user:

[user@hostname ~]$ elinks http://localhost:8080 //says request sent but  no response received.

以上elinks命令无法连接到网址。

它有效!!

[user@hostname ~]$ sudo docker service ps web
ID                  NAME                IMAGE               NODE                           DESIRED STATE       CURRENT STATE           ERROR               PORTS
xxxxxxxxxxxx        web.1               httpd:latest        hostname.myserver.com   Running             Running 3 minutes ago                       
[user@hostname ~]$ 
[user@hostname ~]$ elinks http://hostname.mylabserver.com:80

这适用于连接到在端口80上运行的nginx。

谢谢！
