Red Hat Universal Base Images (UBI)
Red Hat Universal Base Images (UBI) are OCI-compliant, container-based, operating system images with complementary runtime languages and packages that are freely redistributable. Like previous base images, they are built from portions of Red Hat Enterprise Linux (RHEL). You can find UBI images in the Red Hat container catalog, and they are buildable and deployable anywhere.
UBI are designed to be a foundation for cloud-native and web applications use cases developed in containers. Because the images are freely redistributable, you can build a containerized application using UBI, push it to your registry server, easily share it with others, then deploy it on non-Red Hat platforms. And since the application is built on Red Hat Enterprise Linux, you can be confident that Red Hat's UBI are reliable, secure, and performant.
