Publishing Port

Check the port your project is using

Make sure you know which port your application is using, vue3 uses 8080 by default.

Specify port mapping

docker run -p <host_port>:<container_port> --name <name> <container_name|container_id>

Auto assign port mapping

docker run -P

If you mis-assign the EXPOSE in dockerfile, this auto assignment may not result in what you expect.
