About Project Quay

Project Quay is a container registry platform for secure storage, distribution, and governance of containers and cloud-native artifacts. You can deploy it as a standalone component or as an Operator on OpenShift Container Platform.

Project Quay includes the following features and benefits:

  • Granular security management

  • Fast and robust at any scale

  • High velocity CI/CD

  • Automated installation and updates

  • Enterprise authentication and team-based access control

  • OpenShift Container Platform integration

Project Quay is regularly released, containing new features, bug fixes, and software updates. You can upgrade Project Quay for both standalone and OpenShift Container Platform deployments.

Important

Project Quay only supports rolling back, or downgrading, to previous z-stream versions, for example, {producty-n1}.2 → {producty-n1}.1. Rolling back to previous y-stream versions ({producty} → {producty-n1}) is not supported. This is because Project Quay updates might contain database schema upgrades that are applied when upgrading to a new version of Project Quay. Database schema upgrades are not considered backwards compatible.

Downgrading to previous z-streams is neither recommended nor supported by either Operator based deployments or virtual machine based deployments. Downgrading should only be done in extreme circumstances. The decision to rollback your Project Quay deployment must be made in conjunction with the Project Quay support and development teams. For more information, contact Project Quay support.
