why I can't start a docker container because the port be allocated?

Question

Terminal screenshot

use lsof to show a port, but every port return same info...

[kfadmin@master fundrisksys]$ lsof -i:136
24223   /usr/bin/bash   /dev/pts/0
24223   /usr/bin/bash   /dev/pts/0
24223   /usr/bin/bash   /dev/pts/0
24223   /usr/bin/bash   /dev/pts/0

[kfadmin@master fundrisksys]$ lsof -i:7895
24223   /usr/bin/bash   /dev/pts/0
24223   /usr/bin/bash   /dev/pts/0
24223   /usr/bin/bash   /dev/pts/0
24223   /usr/bin/bash   /dev/pts/0

I can't use any port, it shows same info: Bind for 0.0.0.0:8001 failed: port is already allocated

I try to kill the pid, but the terminal will be killed

Did you try to run a docker ps -a? Maybe you have a stopped container that has reserved this port.

Use netstat -tulpn or ss -tulpn and look at used ports. Find app and pid that uses this port.
