Docker Trusted Registry
If you’re anything like me, you think the idea of Docker Hub is a great one, a neat place to store images and even to share them among the community. However, my next inclination is to look at this through an Enterprise spyglass, which quickly turns my perspective from neat to insecure. In other words, you may not be comfortable with placing images in this public repository. Certainly not images that contain anything sensitive to your organization, anyway.
Here is where Docker Trusted Registry may be something to look into. Docker Trusted Registry is a container image repository system, similar in idea to Docker Hub, but it’s something that you can contain within your network, behind your own firewalls and security systems. This gives you a container image repository system without the risk of sharing sensitive information with the rest of the world.
