How to change binding port of Docker private repository in Nexus by using configuration file?

Hi Tai Bui Chi,
There is no config file that holds this value - it is persisted in the database. What I’d suggest is:

  1. Please disable the HTTPS connector (uncheck the check box and save Repository config).
  2. Verify there is nothing using your desired port (18080).
  3. Re-enable the HTTPS connector on your desired port.

I hope that helps.
