我对Docker Swarm有问题。
我已经创建了三个容器（db，back和web）。
Spring image是API REST，我想使用image web_prod（ReactJS）调用路由/用户。
在Swarm中，我有3名经理和3名工人。 所有服务（数据库，后台，Web）都已连接到网络（覆盖）编排。
我可以使用URL http://tasks.back:4000/users（与其他容器-）卷曲我的api，但是当我使用网络图像调用此地址时，没有任何结果。这个另一个容器在我的经理中运行（适当/卷曲）。
可能是集群和服务之间的问题。
检查我的服务网络：
docker@manager1:~$ docker service inspect web

在同一网络上的其他容器中出现：
docker@manager1:~$ docker run --rm -it --net=orchestration --name curl appropriate/curl http://tasks.back:4000/application
{"ip":"10.0.2.29","name":"back.api","id":null,"version":null}
如果您对此有个想法（当我在浏览器中通过图像网络调用api时没有结果） 我尝试使用管理器（192.168.25.80:4000），本地主机，图像名称等IP地址...
谢谢
