We’ll briefly show how to start your own registry server at the end of this blog post. Obviously, the push will fail if no registry server answer locally on the port 5000. # Finally, push the new repository to its home location.ĭocker push localhost.localdomain:5000/ubuntu # The location becomes a permanent part of the repository name.ĭocker tag 8dbd9e392a96 localhost.localdomain:5000/ubuntu # Tag to create a repository with the full registry location. Ubuntu latest 8dbd9e392a96 12 weeks ago 263 MB (virtual 263 MB) # Then, find the image id that corresponds to the ubuntu repositoryĭocker images | grep ubuntu | grep latest Let’s say I want to push the repository “ubuntu” to my local registry, which runs on my local machine, on the port 5000: # First, make sure you have the "ubuntu" repository: It will look like my.registry.address:port/repositoryname. Now the new feature! To push to or pull from your own registry, you just need to add the registry’s location to the repository name. Implicitly that push and pull each access the Central Registry at, so nothing has changed with the default behavior and all the examples still work. # Push the Hipache image (if you're samalba!) The default way of pushing and pulling repositories from the Central Registry has not changed: # Pull the ubuntu base image: You’ll also need the Docker registry code. You’ll need the latest version of Docker (>=0.5.0) to use this new feature, and you must run this version as both the daemon and the client. You can decide if your registry is public or private. Today we are introducing an easy way to share repositories on your own registry so that you can control access to them and still share them among multiple Docker daemons. It is just as easy to push your own image (or collection of tagged images as a repository) to the same public registry so that everyone can benefit from your newly Dockerized service.īut sometimes you can’t share your repository with the world because it contains proprietary code or confidential information. One of the things that makes Docker so useful is how easy it is to pull ready-to-use images from a central location, Docker’s Central Registry.
