Looking for Docker Trusted Registry?
Docker Trusted Registry (DTR) is a commercial product that enables complete image management workflow, featuring LDAP integration, image signing, security scanning, and integration with Universal Control Plane. DTR is offered as an add-on to Docker Enterprise subscriptions of Standard or higher.
Go to Docker Trusted Registry{: class="button outline-btn" }
What it is
The Registry is a stateless, highly scalable server side application that stores and lets you distribute Docker images. The Registry is open-source, under the permissive Apache license.
Why use it
You should use the Registry if you want to:
- tightly control where your images are being stored
- fully own your images distribution pipeline
- integrate image storage and distribution tightly into your in-house development workflow
Alternatives
Users looking for a zero maintenance, ready-to-go solution are encouraged to head-over to the Docker Hub, which provides a free-to-use, hosted Registry, plus additional features (organization accounts, automated builds, and more).
Users looking for a commercially supported version of the Registry should look into Docker Trusted Registry.
Requirements
The Registry is compatible with Docker engine version 1.6.0 or higher.
Basic commands
Start your registry
docker run -d -p 5000:5000 --name registry registry:2
Pull (or build) some image from the hub
docker pull ubuntu
Tag the image so that it points to your registry
docker image tag ubuntu localhost:5000/myfirstimage
Push it
docker push localhost:5000/myfirstimage
Pull it back
docker pull localhost:5000/myfirstimage
Now stop your registry and remove all data
docker container stop registry && docker container rm -v registry
