13.4. 使用 Red Hat Quay API 建立配额

首次创建机构时，它不会应用配额。使用 /api/v1/organization/{organization}/quota 端点：

示例命令

$ curl -k -X GET -H "Authorization: Bearer <token>" -H 'Content-Type: application/json'  https://example-registry-quay-quay-enterprise.apps.docs.gcp.quaydev.org/api/v1/organization/testorg/quota  | jq
Copy to Clipboard Toggle word wrap

输出示例

[]
Copy to Clipboard Toggle word wrap

13.4.1. 设置配额
复制链接

要为机构设置配额，将 POST 数据发送到 /api/v1/organization/{orgname}/quota endpoint: .Sample 命令 

$ curl -k -X POST -H "Authorization: Bearer <token>" -H 'Content-Type: application/json' -d '{"limit_bytes": 10485760}'  https://example-registry-quay-quay-enterprise.apps.docs.quayteam.org/api/v1/organization/testorg/quota | jq
Copy to Clipboard Toggle word wrap

输出示例

"Created"

13.4.2. 查看配额
复制链接

要查看应用的配额，请从 /api/v1/organization/{orgname}/quota 端点中获得 GET 数据：

示例命令

$ curl -k -X GET -H "Authorization: Bearer <token>" -H 'Content-Type: application/json'  https://example-registry-quay-quay-enterprise.apps.docs.gcp.quaydev.org/api/v1/organization/testorg/quota  | jq

    "default_config_exists": false
  }
]
Copy to Clipboard Toggle word wrap

13.4.3. 修改配额
复制链接

要修改现有的配额（在这个实例中从 10 MB 改为 100 MB），使用到 /api/v1/organization/{orgname}/quota/{quota_id} 端点的 PUT 数据：

示例命令

$ curl -k -X PUT -H "Authorization: Bearer <token>" -H 'Content-Type: application/json' -d '{"limit_bytes": 104857600}'  https://example-registry-quay-quay-enterprise.apps.docs.gcp.quaydev.org/api/v1/organization/testorg/quota/1 | jq
Copy to Clipboard Toggle word wrap

13.4.5. 使用配额限制拒绝推送
复制链接

如果镜像推送超过定义的配额限制，则会发生软或硬检查：

  • 对于软检查，或警告，用户会收到通知。
  • 对于硬检查 或拒绝，该推送将被终止。

13.4.5.1. 设置 reject 和 warning 限制
复制链接

要设置 reject 和 warning 限制，请将 POST 数据发送到 /api/v1/organization/{orgname}/quota/{quota_id}/limit 端点：

拒绝限制命令示例

$ curl -k -X POST -H "Authorization: Bearer <token>" -H 'Content-Type: application/json' -d '{"type":"Reject","threshold_percent":80}'  https://example-registry-quay-quay-enterprise.apps.docs.gcp.quaydev.org/api/v1/organization/testorg/quota/1/limit
Copy to Clipboard Toggle word wrap

警告限制命令示例

$ curl -k -X POST -H "Authorization: Bearer <token>" -H 'Content-Type: application/json' -d '{"type":"Warning","threshold_percent":50}'  https://example-registry-quay-quay-enterprise.apps.docs.gcp.quaydev.org/api/v1/organization/testorg/quota/1/limit
Copy to Clipboard Toggle word wrap

13.4.5.2. 查看拒绝和警告限制
复制链接

要查看 reject 和 warning 限制，请使用 /api/v1/organization/{orgname}/quota 端点：

查看配额限制

$  curl -k -X GET -H "Authorization: Bearer <token>" -H 'Content-Type: application/json'  https://example-registry-quay-quay-enterprise.apps.docs.gcp.quaydev.org/api/v1/organization/testorg/quota | jq

[
  {
    "id": 1,
    "limit_bytes": 104857600,
    "default_config": false,
    "limits": [
      {
        "id": 2,
        "type": "Warning",
        "limit_percent": 50
      },
      {
        "id": 1,
        "type": "Reject",
        "limit_percent": 80
      }
    ],
    "default_config_exists": false

13.4.5.3. 超过 reject 限值时推送镜像
复制链接

在本例中，拒绝限制(80%)已设置为当前存储库大小(~83%)的下方，因此下一推送应自动拒绝。

从命令行将示例镜像推送到机构：

镜像推送示例

$ podman pull ubuntu:20.04

$ podman tag docker.io/library/ubuntu:20.04 example-registry-quay-quay-enterprise.apps.docs.gcp.quaydev.org/testorg/ubuntu:20.04

$ podman push --tls-verify=false example-registry-quay-quay-enterprise.apps.docs.gcp.quaydev.org/testorg/ubuntu:20.04
