第3章 Prerequisites for Red Hat Quay on OpenShift


Here are a few things you need to know before you begin the Red Hat Quay on OpenShift deployment:

  • OpenShift cluster: You need a privileged account to an OpenShift 4.2 or later cluster on which to deploy the Red Hat Quay. That account must have the ability to create namespaces at the cluster scope.
  • Storage: AWS cloud storage is used as an example in the following procedure. As an alternative, you can create Ceph cloud storage using steps from the Set up Ceph section of the high availability Red Hat Quay deployment guide. The following is a list of other supported cloud storage:

  • Services: The OpenShift cluster must have enough capacity to run the following containerized services:

    • Database: We recommend you use an enterprise-quality database for production use of Red Hat Quay. PostgreSQL is used as an example in this document. Other options include:

      • Crunchy Data PostgreSQL Operator: Although not supported directly by Red Hat, the CrunchDB Operator is available from Crunchy Data for use with Red Hat Quay. If you take this route, you should have a support contract with Crunchy Data and work directly with them for usage guidance or issues relating to the operator and their database.
      • If your organization already has a high-availability (HA) database, you can use that database with Red Hat Quay. See the Red Hat Quay Support Policy for details on support for third-party databases and other components.
    • Key-value database: Redis is used to serve live builder logs and Red Hat Quay tutorial content to your Red Hat Quay configuration.
    • Red Hat Quay: The quay container provides the features to manage the Red Hat Quay registry.
    • Clair: The clair-jwt container provides Clair scanning services for the registry.
