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
-
创建一个命名空间,如
quay-enterprise
。 - 如果要预先配置部署的各个方面,为 config 捆绑包创建 secret
在名为
quayregistry.yaml
的文件中创建QuayRegistry
自定义资源对于最小部署,使用所有默认值:
quayregistry.yaml:
apiVersion: quay.redhat.com/v1 kind: QuayRegistry metadata: name: example-registry namespace: quay-enterprise
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
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
在指定的命名空间中创建
QuayRegistry
:$ oc create -f quayregistry.yaml
- 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。
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-clair-app-86554c6b49-ds7bl 0/1 ContainerCreating 0 2s example-registry-clair-app-86554c6b49-hxp5s 0/1 Running 1 17s example-registry-clair-postgres-68d8857899-lbc5n 0/1 ContainerCreating 0 17s example-registry-quay-app-upgrade-h2v7h 0/1 ContainerCreating 0 9s example-registry-quay-config-editor-5f646cbcb7-lbnc2 0/1 ContainerCreating 0 17s example-registry-quay-database-66f495c9bc-wqsjf 0/1 ContainerCreating 0 17s example-registry-quay-mirror-854c88457b-d845g 0/1 Init:0/1 0 2s example-registry-quay-mirror-854c88457b-fghxv 0/1 Init:0/1 0 17s 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。

当部署过程成功完成时,QuayRegistry 对象中的状态不会显示不健康的组件:
