You need a privileged account to an OpenShift 4.5 or later cluster on which to deploy the Red Hat Quay Operator. That account must have the ability to create namespaces at the cluster scope.

Each Red Hat Quay application pod has the following resource requirements:

The Red Hat Quay Operator will create at least one application pod per Red Hat Quay deployment it manages. Ensure your OpenShift cluster has sufficient compute resources for these requirements.

By default, the Red Hat Quay Operator uses the ObjectBucketClaim Kubernetes API to provision object storage. Consuming this API decouples the Operator from any vendor-specific implementation. Red Hat OpenShift Data Foundation provides this API via its NooBaa component, which will be used in this example.

Red Hat Quay can be manually configured to use any of the following supported cloud storage options:

To create the first user using the /api/v1/user/initialize API, set the FEATURE_USER_INITIALIZE parameter to true. Unlike all other registry API calls which require an OAuth token that is generated by an OAuth application in an existing organization, the API endpoint does not require authentication.

After you have deployed Red Hat Quay, you can use the API to create a user, for example, quayadmin, assuming that no other users have already been created. For more information see Using the API to create the first user.

Set the config option BROWSER_API_CALLS_XHR_ONLY to false to allow general access to the Red Hat Quay registry API.

After deploying Red Hat Quay, you can create a user. It is suggested that the first user be given administrator privileges with full permissions. Full permissions can be configured in advance by using the SUPER_USER configuration object. For example:

...
SERVER_HOSTNAME: quay-server.example.com
SETUP_COMPLETE: true
SUPER_USERS:
  - quayadmin
...

After you have configured a super user, you can restrict the ability to create new users to the super user group. Set the FEATURE_USER_CREATION to false to restrict user creation. For example:

...
FEATURE_USER_INITIALIZE: true
BROWSER_API_CALLS_XHR_ONLY: false
SUPER_USERS:
- quayadmin
FEATURE_USER_CREATION: false
...

To use new Red Hat Quay 3.8 functionality, enable some or all of the following features:

...
FEATURE_UI_V2: true
FEATURE_LISTEN_IP_VERSION:
FEATURE_SUPERUSERS_FULL_ACCESS: true
GLOBAL_READONLY_SUPER_USERS:
      -
FEATURE_RESTRICTED_USERS: true
RESTRICTED_USERS_WHITELIST:
      -
...

To use new Red Hat Quay 3.7 functionality, enable some or all of the following features:

...
FEATURE_QUOTA_MANAGEMENT: true
FEATURE_BUILD_SUPPORT: true
FEATURE_PROXY_CACHE: true
FEATURE_STORAGE_REPLICATION: true
DEFAULT_SYSTEM_REJECT_QUOTA_BYTES: 102400000
...

The following config.yaml parameters are suggested for automation:

...
FEATURE_USER_INITIALIZE: true
BROWSER_API_CALLS_XHR_ONLY: false
SUPER_USERS:
- quayadmin
FEATURE_USER_CREATION: false
...

Some configuration examples for unmanaged storage are provided in this section for convenience. See the Red Hat Quay configuration guide for full details for setting up object storage.

If you want the Operator to manage object storage for Quay, your cluster needs to be capable of providing object storage via the ObjectBucketClaim API. Using the Red Hat OpenShift Data Foundation (ODF) Operator, there are two supported options available:

To use the standalone instance option, continue reading below. For production deployment of ODF, please refer to the official documentation.

Requirements:

If you are using an externally managed PostgreSQL database, you must manually enable pg_trgm extension for a successful deployment.

This section describes the database configuration fields available for Red Hat Quay deployments.

DB_CONNECTION_ARGS:
  sslmode: verify-ca
  sslrootcert: /path/to/cacert

DB_CONNECTION_ARGS:
  ssl:
    ca: /path/to/cacert

Recommendations:

Use the following procedure to create a config bundle secret that includes your own SSL/TLS certificate and key pair.

Use the following procedure to use an external Redis database.

If you wish to use an external Redis database, set the component as unmanaged in the QuayRegistry instance:

Horizontal Pod Autoscalers (HPAs) have been added to the Clair, Quay, and Mirror pods, so that they now automatically scale during load spikes.

As HPA is configured by default to be managed, the number of Clair, Quay, and Mirror pods is set to two. This facilitates the avoidance of downtime when updating or reconfiguring Red Hat Quay by the Operator or during rescheduling events.

apiVersion: quay.redhat.com/v1
kind: QuayRegistry
metadata:
  name: example-registry
  namespace: quay-enterprise
spec:
  components:
    - kind: horizontalpodautoscaler
      managed: false

Use the following procedure to prevent the Red Hat Quay Operator from creating a route.

If you install the Red Hat Quay Operator in a single namespace, the monitoring component is automatically set to unmanaged. Use the following reference to explicitly disable monitoring.

apiVersion: quay.redhat.com/v1
kind: QuayRegistry
metadata:
  name: example-registry
  namespace: quay-enterprise
spec:
  components:
    - kind: monitoring
      managed: false

To enable monitoring in this scenario, see the section Enabling monitoring when the Red Hat Quay Operator is installed in a single namespace.

To disable mirroring explicitly:

apiVersion: quay.redhat.com/v1
kind: QuayRegistry
metadata:
  name: example-registry
  namespace: quay-enterprise
spec:
  components:
    - kind: mirroring
      managed: false

Use the oc get pods command to view the deployed components:

$ oc get pods -n quay-enterprise

A default deployment shows the following running pods:

As HPA is configured by default to be managed, the number of pods for Quay, Clair and repository mirroring is set to two. This facilitates the avoidance of downtime when updating / reconfiguring Quay via the Operator or during rescheduling events.

$ oc get hpa -n quay-enterprise

In the events, you should see that the change is blocked until you set up the appropriate config:

    - lastTransitionTime: '2022-03-28T12:56:49Z'
      lastUpdateTime: '2022-03-28T12:56:49Z'

        is missing necessary fields
      reason: ConfigInvalid
      status: 'True'

Browse to the config editor endpoint and then enter the username, typically quayconfig, and the corresponding password to access the config tool:

In the following example, you will update your configuration file by changing the default expiration period of deleted tags.

After applying the changes, the config tool notifies you that the changes made have been submitted to your Red Hat Quay deployment:

+

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:

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.

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

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

With Red Hat Quay 3.7, reconfiguring Quay through the UI no longer generates a new login password. The password now generates only once, and remains the same after reconciling QuayRegistry objects.

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

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

The dashboard shows various statistics including:

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:

Select a sample metric, for example, quay_org_rows:

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

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:

Select the QuayPodFrequentlyRestarting rule detail to configure the alert:

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

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

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.

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

In the cluster used in this example, there are three master nodes and six worker nodes:

$ oc get nodes
NAME                                               STATUS   ROLES    AGE     VERSION
user1-jcnp6-master-0.c.quay-devel.internal         Ready    master   3h30m   v1.20.0+ba45583

user1-jcnp6-worker-b-65plj.c.quay-devel.internal   Ready    worker   3h21m   v1.20.0+ba45583
user1-jcnp6-worker-b-jr7hc.c.quay-devel.internal   Ready    worker   3h21m   v1.20.0+ba45583
user1-jcnp6-worker-c-jrq4v.c.quay-devel.internal   Ready    worker   3h21m   v1.20.0+ba45583
user1-jcnp6-worker-c-pwxfp.c.quay-devel.internal   Ready    worker   3h21m   v1.20.0+ba45583
user1-jcnp6-worker-d-h5tv2.c.quay-devel.internal   Ready    worker   3h22m   v1.20.0+ba45583
user1-jcnp6-worker-d-m9gg4.c.quay-devel.internal   Ready    worker   3h21m   v1.20.0+ba45583

Label the final three worker nodes for infrastructure use:

$ oc label node --overwrite user1-jcnp6-worker-c-pwxfp.c.quay-devel.internal node-role.kubernetes.io/infra=
$ oc label node --overwrite user1-jcnp6-worker-d-h5tv2.c.quay-devel.internal node-role.kubernetes.io/infra=
$ oc label node --overwrite user1-jcnp6-worker-d-m9gg4.c.quay-devel.internal node-role.kubernetes.io/infra=

Now, when you list the nodes in the cluster, the last 3 worker nodes will have an added role of infra:

$ oc get nodes
NAME                                               STATUS   ROLES          AGE     VERSION
user1-jcnp6-master-0.c.quay-devel.internal         Ready    master         4h14m   v1.20.0+ba45583
user1-jcnp6-master-1.c.quay-devel.internal         Ready    master         4h15m   v1.20.0+ba45583
user1-jcnp6-master-2.c.quay-devel.internal         Ready    master         4h14m   v1.20.0+ba45583
user1-jcnp6-worker-b-65plj.c.quay-devel.internal   Ready    worker         4h6m    v1.20.0+ba45583
user1-jcnp6-worker-b-jr7hc.c.quay-devel.internal   Ready    worker         4h5m    v1.20.0+ba45583
user1-jcnp6-worker-c-jrq4v.c.quay-devel.internal   Ready    worker         4h5m    v1.20.0+ba45583
user1-jcnp6-worker-c-pwxfp.c.quay-devel.internal   Ready    infra,worker   4h6m    v1.20.0+ba45583
user1-jcnp6-worker-d-h5tv2.c.quay-devel.internal   Ready    infra,worker   4h6m    v1.20.0+ba45583
user1-jcnp6-worker-d-m9gg4.c.quay-devel.internal   Ready    infra,worker   4h6m    v1.20.0+ba45583

With an infra node being assigned as a worker, there is a chance that user workloads could get inadvertently assigned to an infra node. To avoid this, you can apply a taint to the infra node and then add tolerations for the pods you want to control.

$ oc adm taint nodes user1-jcnp6-worker-c-pwxfp.c.quay-devel.internal node-role.kubernetes.io/infra:NoSchedule
$ oc adm taint nodes user1-jcnp6-worker-d-h5tv2.c.quay-devel.internal node-role.kubernetes.io/infra:NoSchedule
$ oc adm taint nodes user1-jcnp6-worker-d-m9gg4.c.quay-devel.internal node-role.kubernetes.io/infra:NoSchedule

If you have already deployed Quay using the Quay Operator, remove the installed operator and any specific namespace(s) you created for the deployment.

Create a Project resource, specifying a node selector and toleration as shown in the following example:

kind: Project
apiVersion: project.openshift.io/v1
metadata:
  name: quay-registry
  annotations:
    openshift.io/node-selector: 'node-role.kubernetes.io/infra='
    scheduler.alpha.kubernetes.io/defaultTolerations: >-
      [{"operator": "Exists", "effect": "NoSchedule", "key":
      "node-role.kubernetes.io/infra"}
      ]

Use the oc apply command to create the project:

$ oc apply -f quay-registry.yaml
project.project.openshift.io/quay-registry created

Any subsequent resources created in the quay-registry namespace should now be scheduled on the dedicated infrastructure nodes.

When installing the Quay Operator, specify the appropriate project namespace explicitly, in this case quay-registry. This will result in the operator pod itself landing on one of the three infrastructure nodes:

$ oc get pods -n quay-registry -o wide
NAME                                    READY   STATUS    RESTARTS   AGE   IP            NODE                                              
quay-operator.v3.4.1-6f6597d8d8-bd4dp   1/1     Running   0          30s   10.131.0.16   user1-jcnp6-worker-d-h5tv2.c.quay-devel.internal

Create the registry as explained earlier, and then wait for the deployment to be ready. When you list the Quay pods, you should now see that they have only been scheduled on the three nodes that you have labelled for infrastructure purposes:

$ oc get pods -n quay-registry -o wide
NAME                                                   READY   STATUS      RESTARTS   AGE     IP            NODE

Use the following procedure check if the cluster-monitoring-config ConfigMap object exists.

Use the following procedure check if the user-workload-monitoring-config ConfigMap object exists.

Use the following procedure to enable monitoring for user-defined projects.

Use the following procedure to create a Service object to expose Red Hat Quay metrics.

Use the following procedure to configure OpenShift Monitoring to scrape the metrics by creating a ServiceMonitor resource.

You can access the metrics in the OpenShift Container Platform console under Monitoring → Metrics. In the Expression field, enter quay_ to see the list of metrics available:

For example, if you have added users to your registry, select the quay-users_rows metric:

Use the following procedure to resize the NooBaa PVC.

After a few minutes (depending on the size of the PVC), the expanded size should reflect in the PVC’s Capacity field.

The following environment variables are used in the Red Hat Quay Operator to override component images:

When the Red Hat Quay Operator is installed in a cluster through the Operator Lifecycle Manager (OLM), the managed component container images can be easily overridden by modifying the ClusterServiceVersion object.

Use the following procedure to apply overrides to a running Operator.

Note that this is done at the Operator level, so every QuayRegistry will be deployed using these same overrides.

Red Hat Quay users can run an unmanaged Clair configuration with the Red Hat Quay OpenShift Container Platform Operator. This feature allows users to create an unmanaged Clair database, or run their custom Clair configuration without an unmanaged database.

An unmanaged Clair database allows the Red Hat Quay Operator to work in a geo-replicated environment, where multiple instances of the Operator must communicate with the same database. An unmanaged Clair database can also be used when a user requires a highly-available (HA) Clair database that exists outside of a cluster.

In some cases, users might want to run a custom Clair configuration with a managed Clair database. This is useful in the following scenarios:

Clair uses a set of components called updaters to handle the fetching and parsing of data from various vulnerability databases. Updaters are set up by default to pull vulnerability data directly from the internet and work for immediate use. However, some users might require Red Hat Quay to run in a disconnected environment, or an environment without direct access to the internet. Clair supports disconnected environments by working with different types of update workflows that take network isolation into consideration. This works by using the clairctl command line interface tool, which obtains updater data from the internet by using an open host, securely transferring the data to an isolated host, and then important the updater data on the isolated host into Clair.

Use this guide to deploy Clair in a disconnected environment.

For more information about Clair updaters, see "Clair updaters".

Java scanning depends on a public, Red Hat provided API service called Code Ready Dependency Analytics (CRDA). CRDA is only available with internet access and is not enabled by default.

Use the following procedure to integrate the CRDA service with a custom API key and enable CRDA for Java and Python scanning.

Clair’s Red Hat Enterprise Linux (RHEL) scanner relies on a Common Product Enumeration (CPE) file to map RPM packages to the corresponding security data to produce matching results. These files are owned by product security and updated daily.

The CPE file must be present, or access to the file must be allowed, for the scanner to properly process RPM packages. If the file is not present, RPM packages installed in the container image will not be scanned.

In addition to uploading CVE information to the database for disconnected Clair installations, you must also make the mapping file available locally:

indexer:
 scanner:
    repo:
      rhel-repository-scanner:
        repo2cpe_mapping_file: /data/cpe-map.json
    package:
      rhel_containerscanner:
        name2repos_mapping_file: /data/repo-map.json

The tls component allows you to control TLS configuration.

If you set tls to unmanaged, you supply your own ssl.cert and ssl.key files. In this instance, if you want your cluster to support builders, you must add both the Quay route and the builder route name to the SAN list in the cert, or use a wildcard.

To add the builder route, use the following format:

[quayregistry-cr-name]-quay-builder-[ocp-namespace].[ocp-domain-name]:443

Builders require SSL/TLS certificates. For more information about SSL/TLS certificates, see Adding TLS certificates to the Red Hat Quay container.

If you are using Amazon Web Service (AWS) S3 storage, you must modify your storage bucket in the AWS console, prior to running builders. See "Modifying your AWS S3 storage bucket" in the following section for the required parameters.

Red Hat Quay geo-replication supports the use of different and multiple replication targets, for example, using AWS S3 storage on public cloud and using Ceph storage on premise. This complicates the key requirement of granting access to all storage backends from all Red Hat Quay pods and cluster nodes. As a result, it is recommended that you use the following:

This will result in the public cloud instance of Red Hat Quay having access to on premise storage, but the network will be encrypted, protected, and will use ACLs, thereby meeting security requirements.

If you cannot implement these security measures, it may be preferable to deploy two distinct Red Hat Quay registries and to use repository mirroring as an alternative to geo-replication.

To update Quay from one minor version to the next, for example, 3.4 → 3.5, you need to change the update channel for the Quay Operator.

For z stream upgrades, for example, 3.4.2 → 3.4.3, updates are released in the major-minor channel that the user initially selected during install. The procedure to perform a z stream upgrade depends on the approvalStrategy as outlined above. If the approval strategy is set to Automatic, the Quay Operator will upgrade automatically to the newest z stream. This results in automatic, rolling Quay updates to newer z streams with little to no downtime. Otherwise, the update must be manually approved before installation can begin.

When upgrading from Red Hat Quay 3.3.z to 3.6.z, some users might receive the following error: Switch auth v3 requires tenant_id (string) in os_options. As a workaround, you can manually update your DISTRIBUTED_STORAGE_CONFIG to add the os_options and tenant_id parameters:

  DISTRIBUTED_STORAGE_CONFIG:
    brscale:
    - SwiftStorage
    - auth_url: http://****/v3
      auth_version: "3"
      os_options:
        tenant_id: ****
        project_name: ocp-base
        user_domain_name: Default
      storage_path: /datastorage/registry
      swift_container: ocp-svc-quay-ha
      swift_password: *****
      swift_user: *****

The subscription of an installed Operator specifies an update channel, which is used to track and receive updates for the Operator. To upgrade the Quay Operator to start tracking and receiving updates from a newer channel, change the update channel in the Subscription tab for the installed Quay Operator. For subscriptions with an Automatic approval strategy, the upgrade begins automatically and can be monitored on the page that lists the Installed Operators.

If an installed Operator has the approval strategy in its subscription set to Manual, when new updates are released in its current update channel, the update must be manually approved before installation can begin. If the Quay Operator has a pending upgrade, this status will be displayed in the list of Installed Operators. In the Subscription tab for the Quay Operator, you can preview the install plan and review the resources that are listed as available for upgrade. If satisfied, click Approve and return to the page that lists Installed Operators to monitor the progress of the upgrade.

The following image shows the Subscription tab in the UI, including the update Channel, the Approval strategy, the Upgrade status and the InstallPlan:

The list of Installed Operators provides a high-level summary of the current Quay installation:

If something goes wrong during the automatic upgrade from QuayEcosystem to QuayRegistry, follow these steps to revert back to using the QuayEcosystem:

The Quay Operator will report errors in its logs and in status.conditions if migrating a QuayEcosystem component fails or is unsupported. All unmanaged components should migrate successfully because no Kubernetes resources need to be adopted and all the necessary values are already provided in Quay’s config.yaml.

Database

Ephemeral database not supported (volumeSize field must be set).

Redis

Nothing special needed.

External Access

Only passthrough Route access is supported for automatic migration. Manual migration required for other methods.

Clair

Nothing special needed.

Object Storage

QuayEcosystem did not have a managed object storage component, so object storage will always be marked as unmanaged. Local storage is not supported.

Repository Mirroring

Nothing special needed.
