How to Modify docker Configuration

  docker, question

For the existing container, how do I operate the original port -p 80:66 to change the port to -p 80:77, that is, to change the mapping from 66 to 77? Do you have to rebuild a container?

After checking the data, it seems that it is impossible to directly modify port expose on the original container at present, and docker update command is not supported. The demand is very high.

It is also a compromise to submit the current container to a mirror image and then run it from the new mirror image.

— update

ModifyDockerfileFrom insideexpose, and then build it.

If you do not want to rebuild the container, you candocker runUse--exposeParameter designation, equivalent to overrideDockerfileThis is the first time I’ve ever seen a movie.
