Docker app port redirection problem

Apps & App Center App Development
#1

My docker app “exposes” port 8080. As this port is used by a couple of technologies, I’d like to redirect it to 8070 and also request port 8070 exclusively. With these settings:

univentiondockerredirect

I’m getting this error:

What am I doing wrong?

If I simply switch the settings (“host port to be forwarded”: 8080, “container port”: 8070), the installation returns successfully. But this is, of course, not what I want.

Hi,

please try to remove the complete list of “ports to be acquired exclusively”. Those two lists (“exclusive” and “redirection”) are in fact put together, so you do not need to specify the ports in two places. The wording in the Provider Portal is not very helpful, though. Adding 8070 to the list of exclusive ports is essentially as if you would have added 8070/8070 to the list of port redirections. Therefore there is a conflict.

I am a bit puzzled why this should lead to such a traceback. I will look into it, but in the meantime, you should be fine with an empty “exclusive ports” list.

#3

Thank you, I’ve removed the ports-exclusive part and I got it to work you.
However, the other error keeps recurring at times and I don’t know why. I’m installing and uninstalling my app many times repeatedly to test it, and it seems the error occurs if I install, uninstall and then reinstall it without any changes in the provider-test-app-center. But I’m not sure…

I think, we found it. This is a very ugly bug and shall be fixed soon. Until then, you need to provide a translation to Description and LongDescription in the Provider Portal (Tab Translation). This indeed has nothing to do with any port configuration but is a general bug in the App Center.
