4장. Virtual builds with Red Hat Quay on OpenShift Container Platform

To build container images in virtualized environments with Red Hat Quay on Red Hat Quay on OpenShift Container Platform, you can use virtual builds. Virtual builds run in unprivileged containers and provide isolation for your build processes.

With virtual builds, the build manager first creates the Job Object resource. Then, the Job Object creates a pod using the quay-builder-image. The quay-builder-image contains the quay-builder binary and the Podman service. The created pod runs as unprivileged. The quay-builder binary then builds the image while communicating status and retrieving build information from the build manager.
