Set port forwarding to existing Docker container

[romko]

hi,

I have problem with my docker containter. I want to setup port forwarding from container to host - the port must be fixed.

I changed value in qnap.json config i I see the value of port forwarding in container settings. But after I started the container the port of the host is changing to random one (allways port numer rises +1)

Maybe I should clear the cache of Container Station?

I had a similar problem as well.
In order to fix the ports, i had to export the container, then reimport it again.
During the import phase, you can define the ports and it will be fixed.
