Upgrade overview

The upgrade procedure for Project Quay depends on the type of installation you are using.

The Project Quay Operator provides a simple method to deploy and manage a Project Quay cluster. This is the preferred procedure for deploying Project Quay on OpenShift.

The Project Quay Operator should be upgraded using the Operator Lifecycle Manager (OLM) as described in the section "Upgrading Quay using the Quay Operator".

The procedure for upgrading a proof of concept or highly available installation of Project Quay and Clair is documented in the section "Standalone upgrade".

Upgrading the Project Quay Operator Overview

The Project Quay Operator follows a synchronized versioning scheme, which means that each version of the Operator is tied to the version of Project Quay and the components that it manages. There is no field on the QuayRegistry custom resource which sets the version of Project Quay to deploy; the Operator can only deploy a single version of all components. This scheme was chosen to ensure that all components work well together and to reduce the complexity of the Operator needing to know how to manage the lifecycles of many different versions of Project Quay on Kubernetes.

Operator Lifecycle Manager

The Project Quay Operator should be installed and upgraded using the Operator Lifecycle Manager (OLM). When creating a Subscription with the default approvalStrategy: Automatic, OLM will automatically upgrade the Project Quay Operator whenever a new version becomes available.

Warning

When the Project Quay Operator is installed by Operator Lifecycle Manager, it might be configured to support automatic or manual upgrades. This option is shown on the OperatorHub page for the Project Quay Operator during installation. It can also be found in the Project Quay Operator Subscription object by the approvalStrategy field. Choosing Automatic means that your Project Quay Operator will automatically be upgraded whenever a new Operator version is released. If this is not desirable, then the Manual approval strategy should be selected.

Upgrading the Project Quay Operator

The standard approach for upgrading installed Operators on OpenShift Container Platform is documented at Upgrading installed Operators.

In general, Project Quay supports upgrades from a prior (N-1) minor version only. For example, upgrading directly from Project Quay 3.0.5 to the latest version of 3.5 is not supported. Instead, users would have to upgrade as follows:

  1. 3.0.5 → 3.1.3

  2. 3.1.3 → 3.2.2

  3. 3.2.2 → 3.3.4

  4. 3.3.4 → 3.4.z

  5. 3.4.z → 3.5.z

This is required to ensure that any necessary database migrations are done correctly and in the right order during the upgrade.

In some cases, Project Quay supports direct, single-step upgrades from prior (N-2, N-3) minor versions. This simplifies the upgrade procedure for customers on older releases. The following upgrade paths are supported for Project Quay 3.13:

  • 3.11.z → 3.13.z

  • 3.12.z → 3.13.z

For users on standalone deployments of Project Quay wanting to upgrade to 3.13, see the Standalone upgrade guide.

Upgrading Project Quay to version 3.13

To update Project Quay from one minor version to the next, for example, 3.12.z → 3.13, you must change the update channel for the Project Quay Operator.

Procedure

  1. In the OpenShift Container Platform Web Console, navigate to Operators → Installed Operators.

  2. Click on the Project Quay Operator.

  3. Navigate to the Subscription tab.

  4. Under Subscription details click Update channel.

  5. Select stable-3.13 → Save.

  6. Check the progress of the new installation under Upgrade status. Wait until the upgrade status changes to 1 installed before proceeding.

  7. In your OpenShift Container Platform cluster, navigate to Workloads → Pods. Existing pods should be terminated, or in the process of being terminated.

  8. Wait for the following pods, which are responsible for upgrading the database and alembic migration of existing data, to spin up: clair-postgres-upgrade, quay-postgres-upgrade, and quay-app-upgrade.

  9. After the clair-postgres-upgrade, quay-postgres-upgrade, and quay-app-upgrade pods are marked as Completed, the remaining pods for your Project Quay deployment spin up. This takes approximately ten minutes.

  10. Verify that the quay-database uses the postgresql-13 image, and clair-postgres pods now uses the postgresql-15 image.

  11. After the quay-app pod is marked as Running, you can reach your Project Quay registry.

Upgrading to the next minor release version

For z stream upgrades, for example, 3.12.1 → 3.12.2, 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 Project Quay Operator upgrades automatically to the newest z stream. This results in automatic, rolling Project Quay updates to newer z streams with little to no downtime. Otherwise, the update must be manually approved before installation can begin.

Upgrading from Project Quay 3.12 to 3.13

With Project Quay 3.13, the volumeSize parameter has been implemented for use with the clairpostgres component of the QuayRegistry custom resource definition (CRD). This replaces the volumeSize parameter that was previously used for the clair component of the same CRD.

If your Project Quay 3.12 QuayRegistry custom resource definition (CRD) implemented a volume override for the clair component, you must ensure that the volumeSize field is included under the clairpostgres component of the QuayRegistry CRD.

Important

Failure to move volumeSize from the clair component to the clairpostgres component will result in a failed upgrade to version 3.13.

For example:

spec:
  components:
  - kind: clair
    managed: true
  - kind: clairpostgres
    managed: true
    overrides:
      volumeSize: <volume_size>

Changing the update channel for the Project Quay Operator

The subscription of an installed Operator specifies an update channel, which is used to track and receive updates for the Operator. To upgrade the Project Quay Operator to start tracking and receiving updates from a newer channel, change the update channel in the Subscription tab for the installed Project 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.

Manually approving a pending Operator upgrade

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 Project Quay Operator has a pending upgrade, this status will be displayed in the list of Installed Operators. In the Subscription tab for the Project 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:

Subscription tab including upgrade Channel and Approval strategy

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

Installed Operators

Upgrading a QuayRegistry resource

When the Project Quay Operator starts, it immediately looks for any QuayRegistries it can find in the namespace(s) it is configured to watch. When it finds one, the following logic is used:

  • If status.currentVersion is unset, reconcile as normal.

  • If status.currentVersion equals the Operator version, reconcile as normal.

  • If status.currentVersion does not equal the Operator version, check if it can be upgraded. If it can, perform upgrade tasks and set the status.currentVersion to the Operator’s version once complete. If it cannot be upgraded, return an error and leave the QuayRegistry and its deployed Kubernetes objects alone.

Upgrading a QuayEcosystem

Upgrades are supported from previous versions of the Operator which used the QuayEcosystem API for a limited set of configurations. To ensure that migrations do not happen unexpectedly, a special label needs to be applied to the QuayEcosystem for it to be migrated. A new QuayRegistry will be created for the Operator to manage, but the old QuayEcosystem will remain until manually deleted to ensure that you can roll back and still access Quay in case anything goes wrong. To migrate an existing QuayEcosystem to a new QuayRegistry, use the following procedure.

Procedure

  1. Add "quay-operator/migrate": "true" to the metadata.labels of the QuayEcosystem.

    $ oc edit quayecosystem <quayecosystemname>
    metadata:
  labels:
    quay-operator/migrate: "true"

  2. Wait for a QuayRegistry to be created with the same metadata.name as your QuayEcosystem. The QuayEcosystem will be marked with the label "quay-operator/migration-complete": "true".

  3. After the status.registryEndpoint of the new QuayRegistry is set, access Project Quay and confirm that all data and settings were migrated successfully.

  4. If everything works correctly, you can delete the QuayEcosystem and Kubernetes garbage collection will clean up all old resources.

Reverting QuayEcosystem Upgrade

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

Procedure

  1. Delete the QuayRegistry using either the UI or kubectl:

    $ kubectl delete -n <namespace> quayregistry <quayecosystem-name>

  2. If external access was provided using a Route, change the Route to point back to the original Service using the UI or kubectl.

Note

If your QuayEcosystem was managing the PostgreSQL database, the upgrade process will migrate your data to a new PostgreSQL database managed by the upgraded Operator. Your old database will not be changed or removed but Project Quay will no longer use it once the migration is complete. If there are issues during the data migration, the upgrade process will exit and it is recommended that you continue with your database as an unmanaged component.

Supported QuayEcosystem Configurations for Upgrades

The Project Quay Operator reports 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 Project Quay’s config.yaml file.

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.

  • LoadBalancer without custom hostname: After the QuayEcosystem is marked with label "quay-operator/migration-complete": "true", delete the metadata.ownerReferences field from existing Service before deleting the QuayEcosystem to prevent Kubernetes from garbage collecting the Service and removing the load balancer. A new Service will be created with metadata.name format <QuayEcosystem-name>-quay-app. Edit the spec.selector of the existing Service to match the spec.selector of the new Service so traffic to the old load balancer endpoint will now be directed to the new pods. You are now responsible for the old Service; the Quay Operator will not manage it.

  • LoadBalancer/NodePort/Ingress with custom hostname: A new Service of type LoadBalancer will be created with metadata.name format <QuayEcosystem-name>-quay-app. Change your DNS settings to point to the status.loadBalancer endpoint provided by the new Service.

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.

Standalone upgrade

In general, Project Quay supports upgrades from a prior (N-1) minor version only. For example, upgrading directly from Project Quay 3.8 to the latest version of 3.13 is not supported. Instead, users would have to upgrade as follows:

  1. 3.8.z → 3.9.z

  2. 3.9.z → 3.10.z

  3. 3.10.z → 3.11.z

  4. 3.11.z → 3.12.z

  5. 3.12.z → 3.13.z

This is required to ensure that any necessary database migrations are done correctly and in the right order during the upgrade.

In some cases, Project Quay supports direct, single-step upgrades from prior (N-2, N-3) minor versions. This exception to the normal, prior minor version-only, upgrade simplifies the upgrade procedure for customers on older releases. The following upgrade paths are supported for Project Quay 3.13:

  • 3.10.z → 3.13.z

  • 3.11.z → 3.13.z

  • 3.12.z → 3.13.z

For users wanting to upgrade the Project Quay Operator, see Upgrading the Project Quay Operator Overview.

This document describes the steps needed to perform each individual upgrade. Determine your current version and then follow the steps in sequential order, starting with your current version and working up to your desired target version.

See the Project Quay Release Notes for information on features for individual releases.

The general procedure for a manual upgrade consists of the following steps:

  1. Stop the Quay and Clair containers.

  2. Backup the database and image storage (optional but recommended).

  3. Start Clair using the new version of the image.

  4. Wait until Clair is ready to accept connections before starting the new version of Quay.

Accessing images

Project Quay image from version 3.4.0 and later are available from registry.redhat.io and registry.access.redhat.com, with authentication set up as described in Red Hat Container Registry Authentication.

Upgrading the Clair PostgreSQL database

If you are upgrading Project Quay to version 13, you must migrate your Clair PostgreSQL database version from PostgreSQL version 13 → version 15. This requires bringing down your Clair PostgreSQL 13 database and running a migration script to initiate the process.

Use the following procedure to upgrade your Clair PostgreSQL database from version 13 → to version 15.

Important

Clair security scans might become temporarily disrupted after the migration procedure has succeeded.
Procedure

  1. Stop the Project Quay container by entering the following command:

    $ sudo podman stop <quay_container_name>

  2. Stop the Clair container by running the following command:

    $ sudo podman stop <clair_container_id>

  3. Run the following Podman process from SCLOrg’s Data Migration procedure, which allows for data migration from a remote PostgreSQL server:

    $ sudo podman run -d --name <clair_migration_postgresql_database> (1)
  -e POSTGRESQL_MIGRATION_REMOTE_HOST=<container_ip_address> \ (2)
  -e POSTGRESQL_MIGRATION_ADMIN_PASSWORD=remoteAdminP@ssword \
  -v </host/data/directory:/var/lib/pgsql/data:Z> \ (3)
  [ OPTIONAL_CONFIGURATION_VARIABLES ]
  registry.redhat.io/rhel8/postgresql-15

    1. Insert a name for your Clair PostgreSQL 15 migration database.

    2. Your new Clair PostgreSQL 15 database container IP address. Can obtained by running the following command: sudo podman inspect -f "{{.NetworkSettings.IPAddress}}" postgresql-quay.

    3. You must specify a different volume mount point than the one from your initial Clair PostgreSQL 13 deployment, and modify the access control lists for said directory. For example:

      $ mkdir -p /host/data/clair-postgresql15-directory
      $ setfacl -m u:26:-wx /host/data/clair-postgresql15-directory

      This prevents data from being overwritten by the new container.

  4. Stop the Clair PostgreSQL 13 container:

    $ sudo podman stop <clair_postgresql13_container_name>

  5. After completing the PostgreSQL migration, run the Clair PostgreSQL 15 container, using the new data volume mount from Step 3, for example, </host/data/clair-postgresql15-directory:/var/lib/postgresql/data>:

    $ sudo podman run -d --rm --name <postgresql15-clairv4> \
  -e POSTGRESQL_USER=<clair_username> \
  -e POSTGRESQL_PASSWORD=<clair_password> \
 	-e POSTGRESQL_DATABASE=<clair_database_name> \
  -e POSTGRESQL_ADMIN_PASSWORD=<admin_password> \
  -p 5433:5432 \
  -v </host/data/clair-postgresql15-directory:/var/lib/postgresql/data:Z> \
    registry.redhat.io/rhel8/postgresql-15

  6. Start the Project Quay container by entering the following command:

    $ sudo podman run -d --rm -p 80:8080 -p 443:8443 --name=quay \
-v /home/<quay_user>/quay-poc/config:/conf/stack:Z \
-v /home/<quay_user>/quay-poc/storage:/datastorage:Z \
{productrepo}/{quayimage}:{productminv}

  7. Start the Clair container by entering the following command:

    $ sudo podman run -d --name clairv4 \
-p 8081:8081 -p 8088:8088 \
-e CLAIR_CONF=/clair/config.yaml \
-e CLAIR_MODE=combo \
registry.redhat.io/quay/clair-rhel8:{productminv}

Upgrading a geo-replication deployment of standalone Project Quay

Use the following procedure to upgrade your geo-replication Project Quay deployment.

Important

  • When upgrading geo-replication Project Quay deployments to the next y-stream release (for example, Project Quay 3.7 → Project Quay 3.8), or geo-replication deployments, you must stop operations before upgrading.

  • There is intermittent downtime down upgrading from one y-stream release to the next.

  • It is highly recommended to back up your Project Quay deployment before upgrading.
Prerequisites

  • You have logged into registry.redhat.io

Note

  4. On System A of your highly available Project Quay deployment, run the new image version, for example, Project Quay 3.13:

    # sudo podman run --restart=always -p 443:8443 -p 80:8080 \
   --sysctl net.core.somaxconn=4096 \
   --name=quay01 \
   -v /mnt/quay/config:/conf/stack:Z \
   -v /mnt/quay/storage:/datastorage:Z \
   -d registry.redhat.io/quay/quay-rhel8:{productminv}

  5. Wait for the new Project Quay container to become fully operational on System A. You can check the status of the container by entering the following command:

    $ sudo podman ps
    Example output
    CONTAINER ID  IMAGE                                      COMMAND         CREATED        STATUS            PORTS                                        NAMES
70b9f38c3fb4  registry.redhat.io/quay/quay-rhel8:v{producty} registry        2 seconds ago   Up 2 seconds ago   0.0.0.0:82->8080/tcp, 0.0.0.0:445->8443/tcp  quay01

  6. Optional: Ensure that Project Quay is fully operation by navigating to the Project Quay UI.

  7. After ensuring that Project Quay on System A is fully operational, run the new image versions on System B and on System C.

    1. On System B of your highly available Project Quay deployment, run the new image version, for example, Project Quay 3.13:

      # sudo podman run --restart=always -p 443:8443 -p 80:8080 \
   --sysctl net.core.somaxconn=4096 \
   --name=quay02 \

   -d registry.redhat.io/quay/quay-rhel8:{productminv}

    2. On System C of your highly available Project Quay deployment, run the new image version, for example, Project Quay 3.13:

      # sudo podman run --restart=always -p 443:8443 -p 80:8080 \
   --sysctl net.core.somaxconn=4096 \
   --name=quay03 \
   -v /mnt/quay/config:/conf/stack:Z \
   -v /mnt/quay/storage:/datastorage:Z \
   -d registry.redhat.io/quay/quay-rhel8:{productminv}

  8. You can check the status of the containers on System B and on System C by entering the following command:

    $ sudo podman ps

Upgrading a geo-replication deployment of Red Hat Quay on OpenShift Container Platform

Use the following procedure to upgrade your geo-replicated Red Hat Quay on OpenShift Container Platform deployment.

Important

  • When upgrading geo-replicated Red Hat Quay on OpenShift Container Platform deployment to the next y-stream release (for example, Project Quay 3.7 → Project Quay 3.8), you must stop operations before upgrading.

  • There is intermittent downtime down upgrading from one y-stream release to the next.

  • It is highly recommended to back up your Red Hat Quay on OpenShift Container Platform deployment before upgrading.
Note
Procedure

This procedure assumes that you are running the Project Quay registry on three or more systems. For this procedure, we will assume three systems named System A, System B, and System C. System A will serve as the primary system in which the Project Quay Operator is deployed.

  1. On System B and System C, scale down your Project Quay registry. This is done by disabling auto scaling and overriding the replica county for Project Quay, mirror workers, and Clair if it is managed. Use the following quayregistry.yaml file as a reference:

    apiVersion: quay.redhat.com/v1
kind: QuayRegistry
metadata:
  name: registry
  namespace: ns
spec:
  components:
    …
    - kind: horizontalpodautoscaler
      managed: false (1)
    - kind: quay
      managed: true
      overrides: (2)
        replicas: 0
    - kind: clair
      managed: true
      overrides:
        replicas: 0
    - kind: mirror
      managed: true
      overrides:
        replicas: 0
    …

    1. Disable auto scaling of Quay, Clair and Mirroring workers

    2. Set the replica count to 0 for components accessing the database and objectstorage

      Note

      You must keep the Project Quay registry running on System A. Do not update the quayregistry.yaml file on System A.

  2. Wait for the registry-quay-app, registry-quay-mirror, and registry-clair-app pods to disappear. Enter the following command to check their status:

    oc get pods -n <quay-namespace>
    Example output
    quay-operator.v3.7.1-6f9d859bd-p5ftc               1/1     Running     0             12m
quayregistry-clair-postgres-7487f5bd86-xnxpr       1/1     Running     1 (12m ago)   12m
quayregistry-quay-app-upgrade-xq2v6                0/1     Completed   0             12m
quayregistry-quay-redis-84f888776f-hhgms           1/1     Running     0             12m

  3. On System A, initiate a Project Quay upgrade to the latest y-stream version. This is a manual process. For more information about upgrading installed Operators, see Upgrading installed Operators. For more information about Project Quay upgrade paths, see Upgrading the Project Quay Operator.

  4. After the new Project Quay registry is installed, the necessary upgrades on the cluster are automatically completed. Afterwards, new Project Quay pods are started with the latest y-stream version. Additionally, new Quay pods are scheduled and started.

  5. Confirm that the update has properly worked by navigating to the Project Quay UI:

    1. In the OpenShift console, navigate to Operators → Installed Operators, and click the Registry Endpoint link.

      Important

      Do not execute the following step until the Project Quay UI is available. Do not upgrade the Project Quay registry on System B and on System C until the UI is available on System A.

  6. Confirm that the update has properly worked on System A, initiate the Project Quay upgrade on System B and on System C. The Operator upgrade results in an upgraded Project Quay installation, and the pods are restarted.

    Note

    Because the database schema is correct for the new y-stream installation, the new pods on System B and on System C should quickly start.

  7. After updating, revert the changes made in step 1 of this procedure by removing overrides for the components. For example:

    apiVersion: quay.redhat.com/v1
kind: QuayRegistry
metadata:
  name: registry
  namespace: ns
spec:
  components:
    …
    - kind: horizontalpodautoscaler
      managed: true (1)
    - kind: quay
      managed: true
    - kind: clair
      managed: true
    - kind: mirror
      managed: true
    …

    1. If the horizontalpodautoscaler resource was set to true before the upgrade procedure, or if you want Project Quay to scale in case of a resource shortage, set it to true.

Upgrade Quay Bridge Operator

To upgrade the Quay Bridge Operator (QBO), change the Channel Subscription update channel in the Subscription tab to the desired channel.

When upgrading QBO from version 3.5 to 3.7, a number of extra steps are required:

  1. You need to create a new QuayIntegration custom resource. This can be completed in the Web Console or from the command line.

    upgrade-quay-integration.yaml
    - apiVersion: quay.redhat.com/v1
  kind: QuayIntegration
  metadata:
    name: example-quayintegration-new
  spec:
    clusterID: openshift (1)
    credentialsSecret:
      name: quay-integration
      namespace: openshift-operators
    insecureRegistry: false
    quayHostname: https://registry-quay-quay35.router-default.apps.cluster.openshift.com

    1. Make sure that the clusterID matches the value for the existing QuayIntegration resource.

  2. Create the new QuayIntegration custom resource:

    $ oc create -f upgrade-quay-integration.yaml

  3. Delete the old QuayIntegration custom resource.

  4. Delete the old mutatingwebhookconfigurations:

    $ oc delete mutatingwebhookconfigurations.admissionregistration.k8s.io quay-bridge-operator

Downgrading Project Quay

Project Quay only supports rolling back, or downgrading, to previous z-stream versions, for example, 3.12.3 → 3.12.2. Rolling back to previous y-stream versions (3.13 → {producty-n1}) is not supported. This is because Project Quay updates might contain database schema upgrades that are applied when upgrading to a new version of Project Quay. Database schema upgrades are not considered backwards compatible.

Important

Downgrading to previous z-streams is neither recommended nor supported by either Operator based deployments or virtual machine based deployments. Downgrading should only be done in extreme circumstances. The decision to rollback your Project Quay deployment must be made in conjunction with the Project Quay support and development teams. For more information, contact Project Quay support.
