14.2. 使用 Red Hat Quay UI 管理命名空间自动运行策略

步骤

1. 标记四个示例镜像，如 busybox，它将推送到启用了 auto-pruning 的存储库。例如：

   $ podman tag docker.io/library/busybox <quay-server.example.com>/<quayadmin>/busybox:test

   $ podman tag docker.io/library/busybox <quay-server.example.com>/<quayadmin>/busybox:test2

   Copy to Clipboard Toggle word wrap

   $ podman tag docker.io/library/busybox <quay-server.example.com>/<quayadmin>/busybox:test3

   Copy to Clipboard Toggle word wrap

   $ podman tag docker.io/library/busybox <quay-server.example.com>/<quayadmin>/busybox:test4

   Copy to Clipboard Toggle word wrap

2. 输入以下命令将四个示例镜像（如 busybox ）推送到启用了 auto-pruning 的存储库：

   $ podman push <quay-server.example.com>/quayadmin/busybox:test

   Copy to Clipboard Toggle word wrap

   $ podman push <quay-server.example.com>/<quayadmin>/busybox:test2

   Copy to Clipboard Toggle word wrap

   $ podman push <quay-server.example.com>/<quayadmin>/busybox:test3

   Copy to Clipboard Toggle word wrap

   $ podman push <quay-server.example.com>/<quayadmin>/busybox:test4

   Copy to Clipboard Toggle word wrap
3. 检查您的存储库中是否有四个标签。
4. 在 Red Hat Quay UI v2 上，单击导航窗格中的 Organizations。
5. 选择您要将 auto-pruning 功能应用到的机构名称，如 test_organization。
6. 单击 Settings。

7. 单击 Auto-Prune Policies。例如：

   

8. 单击下拉菜单并选择所需的策略，例如，按标签数。
9. 选择要保留所需的标签数量。默认情况下，这在 20 个标签中设置。在本例中，要保留的标签数量设置为 3。

步骤

1. 输入以下 POST 命令创建一个新策略，该策略限制机构中允许的标签数：

   $ curl -X POST -H "Authorization: Bearer <access_token>" -H "Content-Type: application/json" -d '{
       "method": "number_of_tags",
       "value": 10
   }' http://<quay-server.example.com>/api/v1/organization/<quayadmin>/autoprunepolicy/

   另外，您可以在创建日期后将标签设置为在指定时间过期：

   $ curl -X POST -H "Authorization: Bearer <access_token>" -H "Content-Type: application/json" -d '{
       "method": "creation_date",
       "value": "7d"
   }' http://<quay-server.example.com>/api/v1/organization/<quayadmin>/autoprunepolicy/

   Copy to Clipboard Toggle word wrap

   输出示例

   {"uuid": "73d64f05-d587-42d9-af6d-e726a4a80d6e"}

   Copy to Clipboard Toggle word wrap

   尝试创建多个策略会返回以下错误：

   {"detail": "Policy for this namespace already exists, delete existing to create new policy", "error_message": "Policy for this namespace already exists, delete existing to create new policy", "error_type": "invalid_request", "title": "invalid_request", "type": "http://<quay-server.example.com>/api/v1/error/invalid_request", "status": 400}

2. 输入以下命令检查您的自动修剪策略：

   $ curl -X GET -H "Authorization: Bearer <access_token>" http://<quay-server.example.com>/api/v1/organization/<quayadmin>/autoprunepolicy/

   Copy to Clipboard Toggle word wrap

   输出示例

   {"policies": [{"uuid": "73d64f05-d587-42d9-af6d-e726a4a80d6e", "method": "creation_date", "value": "7d"}]}

   Copy to Clipboard Toggle word wrap

3. 您可以输入以下命令来删除自动修剪策略：

   $ curl -X DELETE -H "Authorization: Bearer <access_token>" http://<quay-server.example.com>/api/v1/organization/<quayadmin>/autoprunepolicy/

   Copy to Clipboard Toggle word wrap

步骤

1. 输入以下 POST 命令创建一个新策略，该策略限制当前用户的标签数：

   $ curl -X POST -H "Authorization: Bearer <access_token>" -H "Content-Type: application/json" -d '{
       "method": "number_of_tags",
       "value": 10
   }' http://<quay-server.example.com>/api/v1/user/autoprunepolicy/

   Copy to Clipboard Toggle word wrap

   输出示例

   {"uuid": "8c03f995-ca6f-4928-b98d-d75ed8c14859"}

   Copy to Clipboard Toggle word wrap

2. 输入以下命令检查您的自动修剪策略：

   $ curl -X GET -H "Authorization: Bearer <access_token>" http://<quay-server.example.com>/api/v1/user/autoprunepolicy/8c03f995-ca6f-4928-b98d-d75ed8c14859

   Copy to Clipboard Toggle word wrap

   或者，您可以包含 UUID：

   $ curl -X GET -H "Authorization: Bearer <access_token>" http://<quay-server.example.com>/api/v1/user/autoprunepolicy/8c03f995-ca6f-4928-b98d-d75ed8c14859
   {"uuid": "8c03f995-ca6f-4928-b98d-d75ed8c14859", "method": "number_of_tags", "value": 10}

   Copy to Clipboard Toggle word wrap

   输出示例

   {"policies": [{"uuid": "8c03f995-ca6f-4928-b98d-d75ed8c14859", "method": "number_of_tags", "value": 10}]}

   Copy to Clipboard Toggle word wrap

3. 您可以输入以下命令删除自动修剪策略。请注意，删除策略需要 UUID。

   $ curl -X DELETE -H "Authorization: Bearer <access_token>" http://<quay-server.example.com>/api/v1/user/autoprunepolicy/8c03f995-ca6f-4928-b98d-d75ed8c14859

   Copy to Clipboard Toggle word wrap

   输出示例

   {"uuid": "8c03f995-ca6f-4928-b98d-d75ed8c14859"}
