docker error - '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_         


        

Answer 1

Cause

A container with the same name is still existing.

Solution

To reuse the same container name, delete the existing container by:

docker rm 

Explanation

Containers can exist in following states, during which the container name can't be used for another container:

• created
• restarting
• running
• paused
• exited
• dead

You can see containers in running state by using :

docker ps

To show containers in all states and find out if a container name is taken, use:

docker ps -a
