Latest update.

I used expose in docker file and open the port.

However still problem occurs though, @BMitch's answer ports is also the necessary solution in this case.

For now, My first problem is solved. thank you very much.

Latest update.

I have some services in docker-swarm.

Latest update.

I logined manager and check services docker service ls and containers docker container ls.

then found out

service port is open and container port is not open.

When running container manually you can set like -p 8000:8000.

However in this case, container is launched by stack config yml, ports works for service but not for container.

So,How can I open the port of container??

docker service ls

I have some services in docker-swarm.

I am trying some staffs but in vain. So I change the way for test purpose.

Put my services as global on the manager in the most simple way.

In the same way I can access phpmyadmin and visualizer.

But even in this case I can't access to localhost:8000

I am afraid there is something blocking the ports in myapp/djangosrc??

It might be happen??
