Chapter 7. Quay Operator features

7.1. Console monitoring and alerting

Red Hat Quay provides support for monitoring Quay instances that were deployed using the Operator, from inside the OpenShift console. The new monitoring features include a Grafana dashboard, access to individual metrics, and alerting to notify for frequently restarting Quay pods.


To enable the monitoring features, the Operator must be installed in "all namespaces" mode.

7.1.1. Dashboard

In the OpenShift console, navigate to Monitoring → Dashboards and search for the dashboard of your desired Quay registry instance:

Choose Quay dashboard

The dashboard shows various statistics including:

  • The number of Organizations, Repositories, Users and Robot accounts
  • CPU Usage and Max Memory Usage
  • Rates of Image Pulls and Pushes, and Authentication requests
  • API request rate
  • Latencies

Console dashboard

7.1.2. Metrics

You can see the underlying metrics behind the Quay dashboard, by accessing Monitoring → Metrics in the UI. In the Expression field, enter the text quay_ to see the list of metrics available:

Quay metrics

Select a sample metric, for example, quay_org_rows:

Number of Quay organizations

This metric shows the number of organizations in the registry, and it is directly surfaced in the dashboard as well.

7.1.3. Alerting

An alert is raised if the Quay pods restart too often. The alert can be configured by accessing the Alerting rules tab from Monitoring → Alerting in the consol UI and searching for the Quay-specific alert:

Alerting rules

Select the QuayPodFrequentlyRestarting rule detail to configure the alert:

7.2. Clair for Red Hat Quay

Clair v4 (Clair) is an open source application that leverages static code analyses for parsing image content and reporting vulnerabilities affecting the content. Clair is packaged with Red Hat Quay and can be used in both standalone and Operator deployments. It can be run in highly scalable configurations, where components can be scaled separately as appropriate for enterprise environments.

7.2.1. Clair vulnerability databases

Clair uses the following vulnerability databases to report for issues in your images:

  • Ubuntu Oval database
  • Debian Oval database
  • Red Hat Enterprise Linux (RHEL) Oval database
  • SUSE Oval database
  • Oracle Oval database
  • Alpine SecDB database
  • VMWare Photon OS database
  • Amazon Web Services (AWS) UpdateInfo
  • (Python) database

For information about how Clair does security mapping with the different databases, see ClairCore Severity Mapping.

7.2.2. Clair on OpenShift Container Platform

To set up Clair v4 (Clair) on a Red Hat Quay deployment on OpenShift Container Platform, it is recommended to use the Red Hat Quay Operator. By default, the Red Hat Quay Operator will install or upgrade a Clair deployment along with your Red Hat Quay deployment and configure Clair automatically.

7.2.3. Testing Clair

Use the following procedure to test Clair on either a standalone Red Hat Quay deployment, or on an OpenShift Container Platform Operator-based deployment.


  • You have deployed the Clair container image.


  1. Pull a sample image by entering the following command:

    $ podman pull ubuntu:20.04
  2. Tag the image to your registry by entering the following command:

    $ sudo podman tag <>/<user-name>/ubuntu:20.04
  3. Push the image to your Red Hat Quay registry by entering the following command:

    $ sudo podman push --tls-verify=false
  4. Log in to your Red Hat Quay deployment through the UI.
  5. Click the repository name, for example, quayadmin/ubuntu.
  6. In the navigation pane, click Tags.

    Report summary

    Security scan information appears for scanned repository images

  7. Click the image report, for example, 45 medium, to show a more detailed report:

    Report details

    See all vulnerabilities or only those that are fixable

7.3. Federal Information Processing Standard (FIPS) readiness and compliance

The Federal Information Processing Standard (FIPS) developed by the National Institute of Standards and Technology (NIST) is regarded as the highly regarded for securing and encrypting sensitive data, notably in highly regulated areas such as banking, healthcare, and the public sector. Red Hat Enterprise Linux (RHEL) and OpenShift Container Platform support the FIPS standard by providing a FIPS mode, in which the system only allows usage of specific FIPS-validated cryptographic modules like openssl. This ensures FIPS compliance.

Red Hat Quay supports running on FIPS-enabled RHEL and OpenShift Container Platform environments from Red Hat Quay version 3.5.0.
