Offline map cannot be used when docker is running

[miku54]

Hi danielsnider, I encountered a problem similar to rocklinsuv:, ，but I cannot use the same steps to solve the problem.
When I tried to run "sudo docker run -p 8080:8080 -d -t -v ~/mapproxy:/mapproxy danielsnider/mapproxy", it initially downloaded the docker image, and then returned a series of numbers and characters for the second time. For example, "5d23e78...". Then I checked the MapProxy demo http://127.0.0.1:8080/demo, but I could not get the picture of the map when I opened the webpage normally. I also currently live in a country without Google.. (><) Is there a solution to use topographic maps instead of Google Maps instead of WTMS?
