docker群组成限制
我有一个swarm manager和两个swarm节点，我想根据我在docker deamon上定义的一些标签启动一个容器。 这是我试过的命令：
docker -H :2376 run -e constraint:node==docker2 image/restservice docker: Error response from daemon: Unable to find a node that satisfies the following conditions [available container slots] [node==docker2]. 这里是我得到的，如果我与群体运行docker信息。

我错过了吗？
在群模式上，首先你不要运行容器本身。 您运行将运行容器的服务。 而你的约束没有以正确的方式给予服务创造。 我认为最好的方式来学习正确的方法是通过docker服务创buildcli引用。 https://docs.docker.com/engine/reference/commandline/service_create/
