Management

Default

Docker is configured to look for images on Docker Hub by default.

Start/Stop

  • Start your registry
docker run -d -p 5000:5000 --name registry registry:2
  • Stop the registry and remove all data
docker container stop registry && docker container rm -v registry

Push/Pull

When you use

  • the docker pull or docker run commands, the required images are pulled from your configured registry.
  • the docker push command, your image is pushed to your configured registry.

Example:

  • Tag the image so that it points to your registry
docker image tag ubuntu localhost:5000/myfirstimage

docker push localhost:5000/myfirstimage

docker pull localhost:5000/myfirstimage
