Docker - Name is already in use by container

Question

Running the docker registry with below command always throws an error:

dev:tmp me$ docker run 
     -d --name registry-v1 
     -e SETTINGS_FLAVOR=local 
     -e STORAGE_PATH=/registry 
     -e SEARCH_BACKEND=sqlalchemy 
     -e LOGLEVEL=DEBUG 
     -p 5000:5000 
     registry:0.9.1
Error response from daemon: Conflict. The name "registry-v1" is already in use by container f9e5798a82e0. You have to delete (or rename) that container to be able to reuse that name.

How to prevent this error ?

Answer 1

I got confused by this also. There are two commands relevant here:

docker run  # Run a command in a **new** container

docker start  # Start one or more stopped containers
