With OpenShift Dedicated you can interact with images and set up imagestreams, depending on where the images' registries are located, any authentication requirements around those registries, and how you want your builds and deployments to behave.

Images overview

An imagestream comprises any number of container images identified by tags. It presents a single virtual view of related images, similar to a container image repository.

By watching an imagestream, builds and deployments can receive notifications when new images are added or modified and react by performing a build or deployment, respectively.
