Ozone syncs registries so that you can configure accesses to push to registries. This is done by mapping a registry to a microservice for better organization of builds.
Steps to Create a Registry
Once you log in to Ozone, select Setup>Resources>Registries as shown below
Once you are on the registry page, click on the Create a new registry integration button on the top right corner
Once you have created the registry integration that resides with your requirement, you will be able to view the images and the latest tags synced to Ozone under Resources>Setup> Registries
