What is the right way to add data to an existing named volume in Docker?

Question

I was using Docker in the old way, with a volume container:

docker run -d --name jenkins-data jenkins:tag echo \"data-only container for Jenkins\"
         


        

Answer 1

You don't need to start some container to add data to already existing named volume, just create a container and copy data there:

docker container create --name temp -v my-jenkins-volume:/data busybox
docker cp . temp:/data
docker rm temp
