Docker swarm 创建启动服务

docker service create 创建的服务,用docker service ls查看状态是运行中的,但是docker ps查看,没有任何启动。 Since --detach=false was not specified, tasks will be created in the background. In a future release, --detach=false will become the default. 这个又是什么意思。

Is there a way to 'normalize' this, so connecting by name will work no matter how the container is launched?</p> </div>
