Chapter 2. Running Red Hat Quay in debug mode


Red Hat recommends gathering your debugging information when opening a support case. Running Red Hat Quay in debug mode provides verbose logging to help administrators find more information about various issues. Enabling debug mode can speed up the process to reproduce errors and validate a solution for things like geo-replication deployments, Operator deployments, standalone Red Hat Quay deployments, object storage issues, and so on. Additionally, it helps the Red Hat Support to perform a root cause analysis.

2.1. Running a standalone Red Hat Quay deployment in debug mode

Running Red Hat Quay in debug mode provides verbose logging to help administrators find more information about various issues. Enabling debug mode can speed up the process to reproduce errors and validate a solution.

Use the following procedure to run a standalone deployment of Red Hat Quay in debug mode.

Procedure

  1. Enter the following command to run your standalone Red Hat Quay deployment in debug mode:

    $ podman run -p 443:8443 -p 80:8080 -e DEBUGLOG=true  -v /config:/conf/stack -v /storage:/datastorage -d {productrepo}/{quayimage}:{productminv}
    Copy to Clipboard Toggle word wrap
  2. To view the debug logs, enter the following command:

    $ podman logs quay
    Copy to Clipboard Toggle word wrap

2.2. Running the Red Hat Quay Operator in debug mode

Use the following procedure to run the Red Hat Quay Operator in debug mode.

Procedure

  1. Enter the following command to edit the QuayRegistry custom resource definition:

    $ oc edit quayregistry <quay_registry_name> -n <quay_namespace>
    Copy to Clipboard Toggle word wrap
  2. Update the QuayRegistry to add the following parameters:

    spec:
      - kind: quay
        managed: true
        overrides:
          env:
          - name: DEBUGLOG
            value: "true"
    Copy to Clipboard Toggle word wrap
  3. After the Red Hat Quay Operator has restarted with debugging enabled, try pulling an image from the registry. If it is still slow, dump all dogs from all Quay pods to a file, and check the files for more information.
