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

When you are building a new image you often want to run a new container each time and with the same name. I found the easiest way was to start the container with the --rm option:

--rm        Automatically remove the container when it exits

e.g.

docker run --name my-micro-service --rm 

Sadly it's used almost randomly in the examples from the docs
