Names field in docker ps -a command

When I run the "docker ps -a" command following command I fields:

CONTAINER ID        IMAGE                 COMMAND             CREATED             STATUS                      PORTS               NAMES
d69c6f81b591        paigeeworld/centos7   "/bin/bash"         10 minutes ago      Exited (0) 10 minutes ago                       sweet_curran

If I try to do a "docker run -it sweet_curran bash" I get an "unable to find image" error. What the "Names" field used for if I cannot use it to run the image?

If you don't name a container when you run it Docker will make up a random name for you. This is handy for differentiating different invocations of a container without resorting to hex values. You can see by checking the source all of the possible names that could be generated.
