Chapter 4. Red Hat Quay Security Scanning with Clair

Red Hat Quay supports scanning container images for known vulnerabilities with a scanning engine such as Clair. This document explains how to configure Clair with Red Hat Quay.

4.1. Set up Clair in the Red Hat Quay config tool

Enabling Clair in Red Hat Quay consists of:

  • Starting the Red Hat Quay config tool. See the Red Hat Quay deployment guide for the type of deployment you are doing (OpenShift, Basic, or HA) for how to start the config tool for that environment.
  • Enabling security scanning, then generating a private key and PEM file in the config tool
  • Including the key and PEM file in the Clair config file
  • Start the Clair container

The procedure varies, based on whether you are running Red Hat Quay on OpenShift or directly on a host.

4.1.1. Enabling Clair on a Red Hat Quay OpenShift deployment

To set up Clair on Red Hat Quay in OpenShift, see Add Clair image scanning to Red Hat Quay.

4.1.2. Enabling Clair on a Red Hat Quay Basic or HA deployment

To set up Clair on a Red Hat Quay deployment where the container is running directly on the host system, do the following:

  1. Restart the Red Hat Quay config tool: Run the quay container again in config mode, open the configuration UI in a browser, then select Modify an existing configuration. When prompted, upload the quay-config.tar.gz file that was originally created for the deployment.

  2. Enable Security Scanning: Scroll to the Security Scanner section and select the "Enable Security Scanning" checkbox. From the fields that appear you need to create an authentication key and enter the security scanner endpoint. Here’s how:

    • Generate key: Click Create Key, then from the pop-up window type a name for the Clair private key and an optional expiration date (if blank, the key never expires). Then select Generate Key.

    • Copy the Clair key and PEM file: Save the Key ID (to a notepad or similar) and download a copy of the Private Key PEM file (named security_scanner.pem) by selecting "Download Private Key" (if you lose the key, you need to generate a new one). You will need the key and PEM file when you start the Clair container later.

      Close the pop-up when you are done. Here is an example of a completed Security Scanner config:

      Create authentication key and set scan endpoint

  3. Save the configuration: Click Save Configuration Changes and then select Download Configuration to save it to your local system.

  4. Deploy the configuration: To pick up the changes enabling scanning, as well as other changes you may have made to the configuration, unpack the quay-config.tar.gz and copy the resulting files to the config directory. For example: 

    $ tar xvf quay-config.tar.gz
config.yaml  ssl.cert  ssl.key
$ cp config.yaml ssl* /mnt/quay/config
    Copy to Clipboard Toggle word wrap

Next, start the Clair container and associated database, as described in the following sections.
