Issue type:
After deploying my stack in the swarm using a compose file everything work perfectly in the beginning but after a period of time (some times few hours , half day or even a day ) some container are not responding an we can access the service exposed on a specific port.
When I try to debug the issue with the command docker stack services test :
x43gw7k8sf57 test_webapi replicated 1/1 cm.registry.own:5000/cm/webapi:latest *:8888->8888/tcp
As you can see for the main container I can see that the post is published even if it’s not responding (I even checked inside the container and all the services are running perfectly and there is no issue with the api)
But when checking with docker ps

As you can see here the port is not exposed like the other container even though in the compose file the port is published ( ports: - “8888:8888”) and even when I inspect the container :
docker inspect --format='{{.NetworkSettings.Ports}}' 3466a8cce086
map[]
As you can see no port is mapped and for other containers I find all the ports published.
I made the test using swarm with 2 nodes and even in a single node (deploying only on the manager) , the webapi container stop responding every time
