Why is Docker throwing below error message after running below commands ?

Command: docker run -d -p 4444:4444 --name selenium-hub selenium/hub:2.53.0

Error Message:-

C:\Program Files\Docker Toolbox\docker.exe: Error response from daemon: Conflict
. The name "/selenium-hub" is already in use by container 82d881a27df02c0499411f
5c831ed74d25ee1af77f6b7d4ff32e08202fa1b878. You have to remove (or rename) that
container to be able to reuse that name..
See 'C:\Program Files\Docker Toolbox\docker.exe run --help'.

Did you try to rename or reinstall ?
