Chapter 7. Running a custom Clair configuration with a managed Clair database

Procedure

1. Create a Quay configuration bundle secret that includes the clair-config.yaml by entering the following command:

   $ oc create secret generic --from-file config.yaml=./config.yaml --from-file extra_ca_cert_rds-ca-2019-root.pem=./rds-ca-2019-root.pem --from-file clair-config.yaml=./clair-config.yaml config-bundle-secret

   Example Clair config.yaml file

   indexer:
       connstring: host=quay-server.example.com port=5432 dbname=quay user=quayrdsdb password=quayrdsdb sslmode=disable
       layer_scan_concurrency: 6
       migrations: true
       scanlock_retry: 11
   log_level: debug
   matcher:
       connstring: host=quay-server.example.com port=5432 dbname=quay user=quayrdsdb password=quayrdsdb sslmode=disable
       migrations: true
   metrics:
       name: prometheus
   notifier:
       connstring: host=quay-server.example.com port=5432 dbname=quay user=quayrdsdb password=quayrdsdb sslmode=disable
       migrations: true

   Note
   • The database certificate is mounted under /run/certs/rds-ca-2019-root.pem on the Clair application pod in the clair-config.yaml. It must be specified when configuring your clair-config.yaml.
   • An example clair-config.yaml can be found at Clair on OpenShift config.

2. Add the clair-config.yaml file to your bundle secret, for example:

   apiVersion: v1
   kind: Secret
   metadata:
     name: config-bundle-secret
     namespace: quay-enterprise
   data:
     config.yaml: <base64 encoded Quay config>
     clair-config.yaml: <base64 encoded Clair config>

   Note
   • When updated, the provided clair-config.yaml file is mounted into the Clair pod. Any fields not provided are automatically populated with defaults using the Clair configuration module.

3. You can check the status of your Clair pod by clicking the commit in the Build History page, or by running oc get pods -n <namespace>. For example:

   $ oc get pods -n <namespace>
