After checking the information, it seems that it is currently not possible to directly modify the port expose on the original container, and the docker update command does not support it. This demand is very loud.
Submitting the current container into an image and then running it from the new image is also a compromise.
--- update
ModifyDockerfile里的exposeand then build it again.
If you don’t want to rebuild the container, you can expose it indocker run使用--expose参数指定，相当于覆盖Dockerfile.

You shouldn’t be able to change the port now. You can look at the docker update option
