Causes: accidentally use kill -9 to delete the Podman container running java program process, start the container again with an error
Description of the problem: The problem is because the port is occupied, can not start
Solution: This is because the port is occupied, you can only find out which process is occupying the port through netstat (I am showing the PID/slirp4netns ), and then kill the process number of the occupied port PID with kill -9
