Like others have asked, how exactly did you create these containers? If they were through Portainer did you use a compose file in a stack or did you use the GUI the entire way?

This will nuke them assuming you don’t have something recreating them.

docker ps -a # find your rogue container, copy the container id, my example is a0ff66a83c73
docker stop a0ff66a83c73
docker rm a0ff66a83c73

My suggestion is to go through the process you did to try to deploy them and clean it up from that direction.
