docker swarm - unable to connect to nginx container

I have setup Docker swarm on single node and have created a container on it running nginx server but i am unable to connect to nginx server on specified port. Also, i am not able to attach to container. Any help is much appreciated.

[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

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

Above elinks command is unable to connect to url.

Solution

  • It works!!

    [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

    This works and connects to nginx running on port 80.

    Thanks!!
