Chapter 7. Deploying Red Hat Quay using the Operator

Red Hat Quay on OpenShift Container Platform can be deployed using command-line interface or from the OpenShift Container Platform console. The steps are fundamentally the same.

7.1. Deploying Red Hat Quay from the command line

Use the following procedure to deploy Red Hat Quay from using the command-line interface (CLI).

Prerequisites

  • You have logged into OpenShift Container Platform using the CLI.

Procedure

  1. Create a namespace, for example, quay-enterprise, by entering the following command: 

    $ oc new-project quay-enterprise

  2. Optional. If you want to pre-configure any aspects of your Red Hat Quay deployment, create a Secret for the config bundle: 

    $ oc create secret generic quay-enterprise-config-bundle --from-file=config-bundle.tar.gz=/path/to/config-bundle.tar.gz

  3. Create a QuayRegistry custom resource in a file called quayregistry.yaml

    1. For a minimal deployment, using all the defaults:

      quayregistry.yaml:

      apiVersion: quay.redhat.com/v1
kind: QuayRegistry
metadata:
  name: example-registry
  namespace: quay-enterprise

    2. Optional. If you want to have some components unmanaged, add this information in the spec field. A minimal deployment might look like the following example:

      Example quayregistry.yaml with unmanaged components

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

    3. Optional. If you have created a config bundle, for example, init-config-bundle-secret, reference it in the quayregistry.yaml file:

      Example quayregistry.yaml with a config bundle

      apiVersion: quay.redhat.com/v1
kind: QuayRegistry
metadata:
  name: example-registry
  namespace: quay-enterprise
spec:
  configBundleSecret: init-config-bundle-secret

    4. Optional. If you have a proxy configured, you can add the information using overrides for Red Hat Quay, Clair, and mirroring:

      Example quayregistry.yaml with proxy configured

        kind: QuayRegistry
  metadata:
    name: quay37
  spec:
    configBundleSecret: config-bundle-secret
    components:
      - kind: objectstorage
        managed: false
      - kind: route
        managed: true
      - kind: mirror
        managed: true
        overrides:
          env:
            - name: DEBUGLOG
              value: "true"
            - name: HTTP_PROXY
              value: quayproxy.qe.devcluster.openshift.com:3128
            - name: HTTPS_PROXY
              value: quayproxy.qe.devcluster.openshift.com:3128
            - name: NO_PROXY
              value: svc.cluster.local,localhost,quay370.apps.quayperf370.perfscale.devcluster.openshift.com
      - kind: tls
        managed: false
      - kind: clair
        managed: true
        overrides:
          env:
            - name: HTTP_PROXY
              value: quayproxy.qe.devcluster.openshift.com:3128
            - name: HTTPS_PROXY
              value: quayproxy.qe.devcluster.openshift.com:3128
            - name: NO_PROXY
              value: svc.cluster.local,localhost,quay370.apps.quayperf370.perfscale.devcluster.openshift.com
      - kind: quay
        managed: true
        overrides:
          env:
            - name: DEBUGLOG
              value: "true"
            - name: NO_PROXY
              value: svc.cluster.local,localhost,quay370.apps.quayperf370.perfscale.devcluster.openshift.com
            - name: HTTP_PROXY
              value: quayproxy.qe.devcluster.openshift.com:3128
            - name: HTTPS_PROXY
              value: quayproxy.qe.devcluster.openshift.com:3128

  4. Create the QuayRegistry in the specified namespace by entering the following command: 

    $ oc create -n quay-enterprise -f quayregistry.yaml

  5. Enter the following command to see when the status.registryEndpoint is populated: 

    $ oc get quayregistry -n quay-enterprise example-registry -o jsonpath="{.status.registryEndpoint}" -w

7.1.1. Using the API to create the first user

Use the following procedure to create the first user in your Red Hat Quay organization.

Prerequisites

  • The config option FEATURE_USER_INITIALIZE must be set to true.
  • No users can already exist in the database.
Procedure

This procedure requests an OAuth token by specifying "access_token": true.

  1. Open your Red Hat Quay configuration file and update the following configuration fields: 

    FEATURE_USER_INITIALIZE: true
SUPER_USERS:
     -  quayadmin

  2. Stop the Red Hat Quay service by entering the following command: 

    $ sudo podman stop quay

  3. Start the Red Hat Quay service by entering the following command: 

    $ sudo podman run -d -p 80:8080 -p 443:8443 --name=quay -v $QUAY/config:/conf/stack:Z  -v $QUAY/storage:/datastorage:Z {productrepo}/{quayimage}:{productminv}

  4. Run the following CURL command to generate a new user with a username, password, email, and access token: 

    $ curl -X POST -k  http://quay-server.example.com/api/v1/user/initialize --header 'Content-Type: application/json' --data '{ "username": "quayadmin", "password":"quaypass12345", "email": "quayadmin@example.com", "access_token": true}'

    If successful, the command returns an object with the username, email, and encrypted password. For example: 

    {"access_token":"6B4QTRSTSD1HMIG915VPX7BMEZBVB9GPNY2FC2ED", "email":"quayadmin@example.com","encrypted_password":"1nZMLH57RIE5UGdL/yYpDOHLqiNCgimb6W9kfF8MjZ1xrfDpRyRs9NUnUuNuAitW","username":"quayadmin"} # gitleaks:allow

    If a user already exists in the database, an error is returned: 

    {"message":"Cannot initialize user in a non-empty database"}

    If your password is not at least eight characters or contains whitespace, an error is returned: 

    {"message":"Failed to initialize user: Invalid password, password must be at least 8 characters and contain no whitespace."}

  5. Log in to your Red Hat Quay deployment by entering the following command: 

    $ sudo podman login -u quayadmin -p quaypass12345 http://quay-server.example.com --tls-verify=false

    Example output

    Login Succeeded!

7.1.2. Viewing created components using the command line

Use the following procedure to view deployed Red Hat Quay components.

Prerequisites

  • You have deployed Red Hat Quay on OpenShift Container Platform.

Procedure

  1. Enter the following command to view the deployed components: 

    $ oc get pods -n quay-enterprise

    Example output

    NAME                                                   READY   STATUS      RESTARTS   AGE

example-registry-quay-redis-8bd67b647-skgqx            1/1     Running     0          3m42s

7.1.3. Horizontal Pod Autoscaling

A default deployment shows the following running pods:

  • Two pods for the Red Hat Quay application itself (example-registry-quay-app-*`)
  • One Redis pod for Red Hat Quay logging (example-registry-quay-redis-*)
  • One database pod for PostgreSQL used by Red Hat Quay for metadata storage (example-registry-quay-database-*)
  • Two Quay mirroring pods (example-registry-quay-mirror-*)
  • Two pods for the Clair application (example-registry-clair-app-*)
  • One PostgreSQL pod for Clair (example-registry-clair-postgres-*)

Horizontal PPod Autoscaling is configured by default to be managed, and the number of pods for Quay, Clair and repository mirroring is set to two. This facilitates the avoidance of downtime when updating or reconfiguring Red Hat Quay through the Red Hat Quay Operator or during rescheduling events. You can enter the following command to view information about HPA objects: 

$ oc get hpa -n quay-enterprise

Example output

NAME                           REFERENCE                                 TARGETS           MINPODS   MAXPODS   REPLICAS   AGE

7.1.4. Monitoring and debugging the deployment process

Users can now troubleshoot problems during the deployment phase. The status in the QuayRegistry object can help you monitor the health of the components during the deployment an help you debug any problems that may arise.

Procedure

  1. Enter the following command to check the status of your deployment: 

    $ oc get quayregistry -n quay-enterprise -o yaml

    Example output

    Immediately after deployment, the QuayRegistry object will show the basic configuration: 

    apiVersion: v1
items:
- apiVersion: quay.redhat.com/v1
  kind: QuayRegistry
  metadata:
    creationTimestamp: "2021-09-14T10:51:22Z"

        reason: MinimumReplicasUnavailable
        status: "False"
        type: Available

  4. When the deployment process finishes successfully, the status in the QuayRegistry object shows no unhealthy components: 

      status:
    conditions:
    - lastTransitionTime: "2021-09-14T10:52:36Z"
      lastUpdateTime: "2021-09-14T10:52:36Z"

7.2. Deploying Red Hat Quay from the OpenShift Container Platform console

  1. Create a namespace, for example, quay-enterprise.
  2. Select Operators Installed Operators, then select the Quay Operator to navigate to the Operator detail view.
  3. Click 'Create Instance' on the 'Quay Registry' tile under 'Provided APIs'.
  4. Optionally change the 'Name' of the QuayRegistry. This will affect the hostname of the registry. All other fields have been populated with defaults.
  5. Click 'Create' to submit the QuayRegistry to be deployed by the Quay Operator.
  6. You should be redirected to the QuayRegistry list view. Click on the QuayRegistry you just created to see the details view.
  7. Once the 'Registry Endpoint' has a value, click it to access your new Quay registry via the UI. You can now select 'Create Account' to create a user and sign in.

7.2.1. Using the Red Hat Quay UI to create the first user

Use the following procedure to create the first user by the Red Hat Quay UI.

Note

This procedure assumes that the FEATURE_USER_CREATION config option has not been set to false. If it is false, the Create Account functionality on the UI will be disabled, and you will have to use the API to create the first user.

Procedure

  1. In the OpenShift Container Platform console, navigate to Operators Installed Operators, with the appropriate namespace / project.

  2. Click on the newly installed QuayRegistry object to view the details. For example:

    QuayRegistry details

  3. After the Registry Endpoint has a value, navigate to this URL in your browser.

  4. Select Create Account in the Red Hat Quay registry UI to create a user. For example:

    Create Account

  5. Enter the details for Username, Password, Email, and then click Create Account. For example:

    Enter account details
