A Secure Content Workflow from Docker Hub to DTR
Docker Hub is home to the world’s largest library of container images. Millions of individual developers rely on Docker Hub for official and certified container images provided by independent software vendors (ISV) and the countless contributions shared by community developers and open source projects. Large enterprises can benefit from the curated content in Docker Hub by building on top of previous innovations, but these organizations often require greater control over what images are used and where they ultimately live (typically behind a firewall in a data center or cloud-based infrastructure). For these companies, building a secure content engine between Docker Hub and Docker Trusted Registry (DTR) provides the best of both worlds – an automated way to access and “download” fresh, approved content to a trusted registry that they control.
Ultimately, the Hub-to-DTR workflow gives developers a fresh source of validated and secure content to support a diverse set of application stacks and infrastructures; all while staying compliant with corporate standards. Here is an example of how this is executed in Docker Enterprise 3.0:
Image Mirroring
DTR allows customers to set up a mirror to grab content from a Hub repository by constantly polling it and pulling new image Continue reading
