我有2个容器正在使用服务器的端口5001和5000运行。该服务器可以是Docker集群的一部分。当我使用Docker swarm leave --force离开docker群时，我的物理端口的重定向已消失。

[98-swarm-hello-world *]$ docker swarm init
Swarm initialized: current node (srlmoh6a2nm28biifgv7vpjb1) is now a manager.
To add a worker to this swarm, run the following command:
docker swarm join --token SWMTKN-1-1hws6so0lpikgc1e0ztlhpobj7ejvg0hg4lk0k22wsdss4ntri-7l6eoo7cimlhmpzputbjpo6qt 192.168.65.3:2377
To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.

目前端口仍然在这里，但随后是：
[98-swarm-hello-world *]$ docker swarm leave --force
Node left the swarm.

编辑：我的图片可能有问题，另一张图片（使用docker container run --rm --name nginx -p 80:80 -d nginx创建），端口仍然暴露：

编辑2：我的映像没有建立，我只是在运行一个容器。
这是compose file：
