第 4 章 使用 Quay Operator 部署 Quay

Operator 可从命令行或 OpenShift 控制台部署,但基本步骤相同。

4.1. 从命令行部署 Red Hat Quay

  1. 创建一个命名空间,如 quay-enterprise
  2. 如果要预先配置部署的各个方面,为 config 捆绑包创建 secret
  3. 在名为 quayregistry.yaml的文件中创建 QuayRegistry 自定义资源

    1. 对于最小部署,使用所有默认值:

      quayregistry.yaml:

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

    2. 如果要具有一些组件非受管,请在 spec 字段中添加此信息。例如,最小部署可能类似如下:

      quayregistry.yaml:

      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. 如果您已创建了配置捆绑包,如 init-config-bundle-secret,在 quayregistry.yaml 文件中引用它:

      quayregistry.yaml:

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

  4. 在指定的命名空间中创建 QuayRegistry

    $ oc create -f quayregistry.yaml
  5. 如需有关如何跟踪部署进度的信息,请参阅 监控和调试部署过程
  6. 等待 status.registryEndpoint 填充。

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

4.1.1. 使用命令行查看创建的组件

使用 oc get pods 命令查看部署的组件:

$ oc get pods -n quay-enterprise

NAME                                                   READY   STATUS      RESTARTS   AGE
example-registry-clair-app-5ffc9f77d6-jwr9s            1/1     Running     0          3m42s
example-registry-clair-app-5ffc9f77d6-wgp7d            1/1     Running     0          3m41s
example-registry-clair-postgres-54956d6d9c-rgs8l       1/1     Running     0          3m5s
example-registry-quay-app-79c6b86c7b-8qnr2             1/1     Running     4          3m42s
example-registry-quay-app-79c6b86c7b-xk85f             1/1     Running     4          3m41s
example-registry-quay-app-upgrade-5kl5r                0/1     Completed   4          3m50s
example-registry-quay-config-editor-597b47c995-svqrl   1/1     Running     0          3m42s
example-registry-quay-database-b466fc4d7-tfrnx         1/1     Running     2          3m42s
example-registry-quay-mirror-6d9bd78756-6lj6p          1/1     Running     0          2m58s
example-registry-quay-mirror-6d9bd78756-bv6gq          1/1     Running     0          2m58s
example-registry-quay-postgres-init-dzbmx              0/1     Completed   0          3m43s
example-registry-quay-redis-8bd67b647-skgqx            1/1     Running     0          3m42s

4.1.2. Pod 横向自动扩展(HPA)

默认部署显示了以下正在运行的 pod:

  • Quay 应用本身的两个 pod(example-registry-quay-app-*')
  • 用于 Quay 日志记录的 Redis pod(example-registry-quay-redis-*)
  • Quay 用于元数据存储的 PostgreSQL 的一个数据库 pod(example-registry-quay-database-*)
  • 用于 Quay 配置编辑器的一个 pod(example-registry-quay-config-editor-*)
  • 两个 Quay 镜像 pod(example-registry-quay-mirror-*)
  • Clair 应用的两个 pod(example-registry-clair-app-*)
  • Clair 的 PostgreSQL pod(example-registry-clair-postgres-*)

因为 HPA 默认配置为 受管,Quay 的 pod 数量将 Clair 和存储库镜像设置为 2。这有助于在通过 Operator 更新/配置 Quay 或重新调度事件期间出现停机的问题。

$ oc get hpa -n quay-enterprise
NAME                           REFERENCE                                 TARGETS           MINPODS   MAXPODS   REPLICAS   AGE
example-registry-clair-app     Deployment/example-registry-clair-app     16%/90%, 0%/90%   2         10        2          13d
example-registry-quay-app      Deployment/example-registry-quay-app      31%/90%, 1%/90%   2         20        2          13d
example-registry-quay-mirror   Deployment/example-registry-quay-mirror   27%/90%, 0%/90%   2         20        2          13d

4.1.3. 使用 API 创建第一个用户

当使用 API 创建第一个用户时,必须满足以下条件:

  • 配置选项 FEATURE_USER_INITIALIZE 必须设置为 true
  • 数据库中没有用户

如需有关预配置部署的更多信息,请参阅 预配置 Quay 以实现自动化

4.1.3.1. 调用 API

使用 status.registryEndpoint URL,调用 /api/v1/user/initialize API,传递用户名、密码和电子邮件地址。您还可以通过指定 "access_token": true 来请求 OAuth 令牌。

$  curl -X POST -k  https://example-registry-quay-quay-enterprise.apps.docs.quayteam.org/api/v1/user/initialize --header 'Content-Type: application/json' --data '{ "username": "quayadmin", "password":"quaypass123", "email": "quayadmin@example.com", "access_token": true}'
{"access_token":"6B4QTRSTSD1HMIG915VPX7BMEZBVB9GPNY2FC2ED", "email":"quayadmin@example.com","encrypted_password":"1nZMLH57RIE5UGdL/yYpDOHLqiNCgimb6W9kfF8MjZ1xrfDpRyRs9NUnUuNuAitW","username":"quayadmin"}

如果成功,该方法返回一个带有用户名、电子邮件和加密密码的对象。如果用户已存在于数据库中,则返回错误:

$  curl -X POST -k  https://example-registry-quay-quay-enterprise.apps.docs.quayteam.org/api/v1/user/initialize --header 'Content-Type: application/json' --data '{ "username": "quayuser2", "password":"quaypass123", "email": "quayuser2@example.com"}'
{"message":"Cannot initialize user in a non-empty database"}

密码必须至少为 8 个字符,且不包含空格:

 $  curl -X POST -k  https://example-registry-quay-quay-enterprise.apps.docs.quayteam.org/api/v1/user/initialize --header 'Content-Type: application/json' --data '{ "username": "quayadmin", "password":"pass123", "email": "quayadmin@example.com"}'
{"message":"Failed to initialize user: Invalid password, password must be at least 8 characters and contain no whitespace."}

4.1.3.2. 使用 OAuth 令牌

现在,您可以在指定返回的 OAuth 代码调用 Quay API 的剩余部分。例如,获取当前用户的列表:

$ curl -X GET -k -H "Authorization: Bearer 6B4QTRSTSD1HMIG915VPX7BMEZBVB9GPNY2FC2ED" https://example-registry-quay-quay-enterprise.apps.docs.quayteam.org/api/v1/superuser/users/
{
    "users": [
        {
            "kind": "user",
            "name": "quayadmin",
            "username": "quayadmin",
            "email": "quayadmin@example.com",
            "verified": true,
            "avatar": {
                "name": "quayadmin",
                "hash": "3e82e9cbf62d25dec0ed1b4c66ca7c5d47ab9f1f271958298dea856fb26adc4c",
                "color": "#e7ba52",
                "kind": "user"
            },
            "super_user": true,
            "enabled": true
        }
    ]
}

在本例中,quayadmin 用户的详细信息返回,因为它是目前创建的唯一用户。

4.1.3.2.1. 创建机构

要创建机构,使用 POST 调用 api/v1/organization/ 端点:

$ curl -X POST -k --header 'Content-Type: application/json' -H "Authorization: Bearer 6B4QTRSTSD1HMIG915VPX7BMEZBVB9GPNY2FC2ED" https://example-registry-quay-quay-enterprise.apps.docs.quayteam.org/api/v1/organization/ --data '{"name": "testorg", "email": "testorg@example.com"}'
"Created"
4.1.3.2.2. 获取机构详情

检索您创建的机构详情:

$ curl -X GET -k --header 'Content-Type: application/json' -H "Authorization: Bearer 6B4QTRSTSD1HMIG915VPX7BMEZBVB9GPNY2FC2ED" https://min-registry-quay-quay-enterprise.apps.docs.quayteam.org/api/v1/organization/testorg
{
    "name": "testorg",
    "email": "testorg@example.com",
    "avatar": {
        "name": "testorg",
        "hash": "5f113632ad532fc78215c9258a4fb60606d1fa386c91b141116a1317bf9c53c8",
        "color": "#a55194",
        "kind": "user"
    },
    "is_admin": true,
    "is_member": true,
    "teams": {
        "owners": {
            "name": "owners",
            "description": "",
            "role": "admin",
            "avatar": {
                "name": "owners",
                "hash": "6f0e3a8c0eb46e8834b43b03374ece43a030621d92a7437beb48f871e90f8d90",
                "color": "#c7c7c7",
                "kind": "team"
            },
            "can_view": true,
            "repo_count": 0,
            "member_count": 1,
            "is_synced": false
        }
    },
    "ordered_teams": [
        "owners"
    ],
    "invoice_email": false,
    "invoice_email_address": null,
    "tag_expiration_s": 1209600,
    "is_free_account": true
}

4.1.4. 监控和调试部署过程

Red Hat Quay 3.6 提供了新的功能,可在部署阶段排除问题。QuayRegistry 对象中的状态可帮助您在部署过程中监控组件的健康状态,以帮助您调试可能出现的问题:

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

部署后,QuayRegistry 对象会显示基本配置:

apiVersion: v1
items:
- apiVersion: quay.redhat.com/v1
  kind: QuayRegistry
  metadata:
    creationTimestamp: "2021-09-14T10:51:22Z"
    generation: 3
    name: example-registry
    namespace: quay-enterprise
    resourceVersion: "50147"
    selfLink: /apis/quay.redhat.com/v1/namespaces/quay-enterprise/quayregistries/example-registry
    uid: e3fc82ba-e716-4646-bb0f-63c26d05e00e
  spec:
    components:
    - kind: postgres
      managed: true
    - kind: clair
      managed: true
    - kind: redis
      managed: true
    - kind: horizontalpodautoscaler
      managed: true
    - kind: objectstorage
      managed: true
    - kind: route
      managed: true
    - kind: mirror
      managed: true
    - kind: monitoring
      managed: true
    - kind: tls
      managed: true
    configBundleSecret: example-registry-config-bundle-kt55s
kind: List
metadata:
  resourceVersion: ""
  selfLink: ""

使用 oc get pods 命令查看部署组件的当前状态:

$ oc get pods -n quay-enterprise

NAME                                                   READY   STATUS              RESTARTS   AGE

example-registry-quay-postgres-init-bktdt              0/1     Terminating         0          17s
example-registry-quay-redis-f9b9d44bf-4htpz            0/1     ContainerCreating   0          17s

在部署进行过程中,QuayRegistry 对象会显示当前状态。在本实例中,数据库迁移就位,其他组件也等到此完成后才会等待。
