  1. Click on the link for the config editor secret:

    Config editor secret

  2. In the Data section of the Secret details screen, click Reveal values to see the credentials for logging in to the config editor:

4.1.3. Changing configuration
Copier lien

In this example of updating the configuration, a superuser is added via the config editor tool:

  1. Add an expiration period, for example 4w, for the time machine functionality:

    Add expiration period

  2. Select Validate Configuration Changes to ensure that the changes are valid

  3. Apply the changes by pressing the Reconfigure Quay button:

    Reconfigure

  4. The config tool notifies you that the change has been submitted to Quay:

    Reconfigured

Note

Reconfiguring Red Hat Quay using the config tool UI can lead to the registry being unavailable for a short time, while the updated configuration is applied.

4.2. Monitoring reconfiguration in the UI

4.2.1. QuayRegistry resource
Copier lien

After reconfiguring the Operator, you can track the progress of the redeployment in the YAML tab for the specific instance of QuayRegistry, in this case, example-registry:

ui monitor deploy update

Each time the status changes, you will be prompted to reload the data to see the updated version. Eventually, the Operator will reconcile the changes, and there will be no unhealthy components reported.

ui monitor deploy done

4.2.2. Events
Copier lien

The Events tab for the QuayRegistry shows some events related to the redeployment:

ui monitor deploy streaming events

Streaming events, for all resources in the namespace that are affected by the reconfiguration, are available in the OpenShift console under Home Events:

ui monitor deploy streaming events

4.3. Accessing updated information after reconfiguration
Copier lien

4.3.1. Accessing the updated config tool credentials in the UI
Copier lien

Since a new pod has been created for the config tool, a new secret will have been created, and you will need to use the updated password when you next attempt to login:

Config editor secret updated

4.3.2. Accessing the updated config.yaml in the UI
Copier lien

Use the config bundle to access the updated config.yaml file.

  1. On the QuayRegistry details screen, click on the Config Bundle Secret
  2. In the Data section of the Secret details screen, click Reveal values to see the config.yaml file

  3. Check that the change has been applied. In this case, 4w should be in the list of TAG_EXPIRATION_OPTIONS: 

    ...
SERVER_HOSTNAME: example-quay-openshift-operators.apps.docs.quayteam.org
SETUP_COMPLETE: true
SUPER_USERS:
- quayadmin
TAG_EXPIRATION_OPTIONS:
