使用自定义约束条件管理 Cloud Load Balancing 资源

Google Cloud 组织政策可让您以编程方式集中控制组织的资源。作为组织政策管理员，您可以定义组织政策，这是一组称为限制条件的限制，会应用于Google Cloud 资源层次结构中的Google Cloud 资源及其后代。您可以在组织、文件夹或项目级强制执行组织政策。

组织政策为各种Google Cloud 服务提供预定义限制条件。但是，如果您想要更精细地控制和自定义组织政策中受限的特定字段，还可以创建自定义限制条件并在自定义组织政策中使用这些自定义限制条件。

以下负载均衡组件支持自定义限制条件：

实例群组等 Compute Engine 资源和 VPC 网络和子网等 VPC 资源也支持自定义限制条件。

优势

费用管理：使用自定义组织政策限制健康检查探测频率。
安全、合规性和治理：您可以使用自定义组织政策强制执行政策。例如：
- 强制使用特定的健康检查协议或端口范围
- 禁止使用特定的后端流量协议
- 要求后端存储桶启用 Cloud CDN
- 要求转发规则使用特定的 Network Service Tiers

对于其他受支持的计算资源，请参阅 Compute Engine 自定义限制条件页面了解详情。

政策继承

如果您对资源强制执行政策，默认情况下，该资源的后代会继承组织政策。例如，如果您对某个文件夹强制执行一项政策， Google Cloud 会对该文件夹中的所有项目强制执行该政策。如需详细了解此行为及其更改方式，请参阅层次结构评估规则。

准备工作

如果您尚未设置身份验证，请进行设置。身份验证用于验证您的身份，以便访问 Google Cloud 服务和 API。如需从本地开发环境运行代码或示例，您可以通过选择以下选项之一向 Compute Engine 进行身份验证：
Select the tab for how you plan to use the samples on this page:
Console

When you use the Google Cloud console to access Google Cloud services and APIs, you don't need to set up authentication.
gcloud
1. 安装 Google Cloud CLI。安装完成后，运行以下命令来初始化 Google Cloud CLI：
  gcloud init
  如果您使用的是外部身份提供方 (IdP)，则必须先使用联合身份登录 gcloud CLI。
  
  注意：如果您之前安装了 gcloud CLI，请确保通过运行 gcloud components update 来获得最新版本。
2. Set a default region and zone.

请确保您知道您的组织 ID。

所需的角色

如需获得管理 Cloud Load Balancing 资源的组织政策所需的权限，请让您的管理员为您授予以下 IAM 角色：

组织 resource_types 的 Organization Policy Administrator (roles/orgpolicy.policyAdmin)
测试负载均衡资源的限制条件：项目资源的 Compute Load Balancer Admin (v1) (roles/compute.loadBalancerAdmin.v1)

如需详细了解如何授予角色，请参阅管理对项目、文件夹和组织的访问权限。

这些预定义角色包含管理 Cloud Load Balancing 资源的组织政策所需的权限。如需查看所需的确切权限，请展开所需权限部分：

所需权限

您需要具备以下权限，才能管理 Cloud Load Balancing 资源的组织政策：

orgpolicy.constraints.list
orgpolicy.policies.create
orgpolicy.policies.delete
orgpolicy.policies.list
orgpolicy.policies.update
orgpolicy.policy.get
orgpolicy.policy.set

您也可以使用自定义角色或其他预定义角色来获取这些权限。

设置自定义限制条件

自定义限制条件由实施组织政策的服务支持的资源、方法、条件和操作定义。自定义限制条件的条件使用通用表达式语言 (CEL) 进行定义。如需详细了解如何使用 CEL 构建自定义限制条件中的条件，请参阅创建和管理自定义组织政策的 CEL 部分。

您可以使用 Google Cloud 控制台或 gcloud CLI 创建自定义限制条件并将其设置为在组织政策中使用。

控制台

在 Google Cloud 控制台中，转到组织政策页面。

转到组织政策
选择页面顶部的项目选择器。
在选择资源窗口中，选择要为其创建自定义限制条件的组织。
点击 自定义限制条件。
在显示名称框中，为限制条件输入一个易记的名称。此字段的最大长度为 200 个字符。请勿在限制条件名称中使用 PII 或敏感数据，因为这些可能会在错误消息中公开。
在限制条件 ID 框中，为新的自定义限制条件输入所需的名称。自定义限制条件必须以 custom. 开头，只能包含大写字母、小写字母或数字，例如 custom.enforceTCPHealthCheckPort1024。该字段的长度上限为 70 个字符，不计算前缀（例如 organizations/123456789/customConstraints/custom.）。
在说明框中，输入直观易懂的限制条件说明，在违反政策时此说明内容会以错误消息的形式显示。此字段的最大长度为 2000 个字符。
在资源类型框中，选择包含要限制的对象和字段的 Google CloudREST 资源的名称。例如 compute.googleapis.com/HealthCheck。
在强制执行方法下，选择是否对 REST CREATE 方法强制执行限制条件。
如需定义条件，请点击 修改条件。
1. 在添加条件面板中，创建一个引用受支持的服务资源的 CEL 条件，例如 resource.tcpHealthCheck.port >= 1024。此字段的最大长度为 1,000 个字符。
2. 点击保存。
在操作下，选择在满足上述条件时是允许还是拒绝评估的方法。
点击创建限制条件。

在每个字段中输入值后，右侧将显示此自定义限制条件的等效 YAML 配置。

gcloud

如需使用 gcloud CLI 创建自定义限制条件，请为自定义限制条件创建 YAML 文件：

name: organizations/ORGANIZATION_ID/customConstraints/CONSTRAINT_NAME
resource_types:
- compute.googleapis.com/RESOURCE_NAME
method_types:
- CREATE
- UPDATE
condition: CONDITION
action_type: ACTION
display_name: DISPLAY_NAME
description: DESCRIPTION

替换以下内容：

ORGANIZATION_ID：您的组织 ID，例如 123456789。
CONSTRAINT_NAME：新的自定义限制条件的名称。自定义限制条件必须以 custom. 开头，只能包含大写字母、小写字母或数字。例如 custom.enforceTCPHealthCheckPort1024。该字段的长度上限为 70 个字符，不计算前缀（例如 organizations/123456789/customConstraints/custom.）。
RESOURCE_NAME：包含要限制的对象和字段的 Compute Engine API REST 资源的名称（而非 URI）。例如 HealthCheck。
CONDITION：针对受支持的服务资源的表示法编写的 CEL 条件。此字段的最大长度为 1,000 个字符。如需详细了解可用于针对其编写条件的资源，请参阅支持的资源。例如 "resource.tcpHealthCheck.port >= 1024"。
ACTION：满足 condition 时要执行的操作。可以是 ALLOW 或 DENY。
DISPLAY_NAME：限制条件的直观易记名称。此字段的最大长度为 200 个字符。
DESCRIPTION：直观易懂的限制条件说明，在违反政策时显示为错误消息。此字段的最大长度为 2000 个字符。

如需详细了解如何创建自定义限制条件，请参阅创建和管理自定义组织政策。

为新的自定义限制条件创建 YAML 文件后，您必须对其进行设置，以使其可用于组织中的组织政策。如需设置自定义限制条件，请使用 gcloud org-policies set-custom-constraint 命令：

gcloud org-policies set-custom-constraint CONSTRAINT_PATH

将 CONSTRAINT_PATH 替换为自定义限制条件文件的完整路径。例如 /home/user/customconstraint.yaml。完成后，您的自定义限制条件会成为 Google Cloud 组织政策列表中的组织政策。如需验证自定义限制条件是否存在，请使用 gcloud org-policies list-custom-constraints 命令：

gcloud org-policies list-custom-constraints --organization=ORGANIZATION_ID

将 ORGANIZATION_ID 替换为您的组织资源的 ID。如需了解详情，请参阅查看组织政策。

强制执行自定义限制条件

如需强制执行限制条件，您可以创建引用该限制条件的组织政策，并将该组织政策应用于 Google Cloud 资源。

控制台

在 Google Cloud 控制台中，前往组织政策页面。
转到组织政策
在项目选择器中，选择要设置组织政策的项目。
从组织政策页面上的列表中选择您的限制条件，以查看该限制条件的政策详情页面。
如需为该资源配置组织政策，请点击管理政策。
在修改政策页面，选择覆盖父级政策。
点击添加规则。
在强制执行部分中，选择开启还是关闭此组织政策的强制执行。
（可选）如需使组织政策成为基于某个标记的条件性政策，请点击添加条件。请注意，如果您向组织政策添加条件规则，则必须至少添加一个无条件规则，否则无法保存政策。如需了解详情，请参阅设置带有标记的组织政策。
点击测试更改以模拟组织政策的效果。政策模拟不适用于旧版托管式限制。如需了解详情，请参阅使用 Policy Simulator 测试组织政策更改。
若要完成并应用组织政策，请点击设置政策。该政策最长需要 15 分钟才能生效。

gcloud

如需创建包含布尔值规则的组织政策，请创建引用该限制条件的 YAML 政策文件：

      name: projects/PROJECT_ID/policies/CONSTRAINT_NAME
      spec:
        rules:
        - enforce: true

请替换以下内容：

PROJECT_ID：要对其实施限制条件的项目。
CONSTRAINT_NAME：您为自定义限制条件定义的名称。例如，custom.enforceTCPHealthCheckPort1024。

如需强制执行包含限制条件的组织政策，请运行以下命令：

    gcloud org-policies set-policy POLICY_PATH

将 POLICY_PATH 替换为组织政策 YAML 文件的完整路径。该政策最长需要 15 分钟才能生效。

示例：使用自定义限制条件限制 TLS 功能

如需使用自定义限制条件对支持的负载均衡器限制 TLS 功能，请在组织中定义使用预定义 constraints/compute.requireSslPolicy 限制条件的政策。定义政策后，请按照以下步骤设置自定义限制条件并使用它们。

为自定义限制条件创建 YAML 文件。

name: organizations/ORGANIZATION_ID/customConstraints/custom.CONSTRAINT_NAME
resource_types: compute.googleapis.com/SslPolicy
methodTypes:
- CREATE
- UPDATE
condition: resource.FIELD_NAME == VALUE
action_type: ACTION
display_name: DISPLAY_NAME
description: DESCRIPTION

以下示例将最低 TLS 版本限制为 1.2：

name: organizations/012345678901/customConstraints/custom.restrictLbTlsVersion
resource_types: compute.googleapis.com/SslPolicy
methodTypes:
- CREATE
- UPDATE
condition: resource.minTlsVersion == "TLS_1_2"
action_type: ALLOW
display_name: Restrict Load Balancing TLS version to 1.2
description: Only allow SSL policies to be created or updated if the minimum TLS version is 1.2 where this custom constraint is enforced.

以下是另一个自定义限制条件的示例，该限制条件仅允许在满足以下条件时创建 SSL 资源：

最低 TLS 版本设置为 1.2。
SSL 政策具有 CUSTOM 配置文件，可让您单独选择 SSL 功能。
SSL 政策不包含 ChaCha20-Poly1305 加密套件。

name: organizations/ORGANIZATION_ID/customConstraints/custom.restrictLbTlsCapabilities
resourceTypes:
- compute.googleapis.com/SslPolicy
methodTypes:
- CREATE
- UPDATE
condition: resource.minTlsVersion == "TLS_1_2" && resource.profile ==
"CUSTOM" && !resource.customFeatures.exists(feature, feature.contains("CHACHA20_POLY1305"))
actionType: ALLOW
displayName: Restrict Load Balancing TLS Capabilities
description: Only allow SSL Policy resources to be created or updated if the minimum TLS version is 1.2, profile is CUSTOM, and no ChaCha20-Poly1305 cipher suite is used where this custom constraint is enforced.

将自定义限制条件添加到您的组织。

gcloud org-policies set-custom-constraint PATH_TO_FILE

验证您的组织中是否存在自定义限制条件。

gcloud org-policies list-custom-constraints \
    --organization=ORGANIZATION_ID

为限制条件创建政策文件。
```
name: projects/PROJECT_ID/policies/custom.CONSTRAINT_NAME
spec:
  rules:
  – enforce: true
```
替换以下内容：
- PROJECT_ID：您的 Google Cloud 项目 ID
- CONSTRAINT_NAME：限制条件名称
强制执行该政策：
```
gcloud org-policies set-policy PATH_TO_POLICY_FILE
```
将 PATH_TO_POLICY_FILE 替换为政策文件的完全限定路径。

假设您已创建了 YAML 文件以将最低 TLS 版本限制为 1.2，请通过创建将 minTlsVersion 设置为 TLS_1_0 的 SSL 政策来测试限制条件：

gcloud compute ssl-policies create SSL_POLICY_NAME \
    --min-tls-version=1.0 \
    --project=PROJECT_ID

输出类似于以下内容：

ERROR: (gcloud.compute.ssl-policies.update) HTTPError 412: Operation
denied by custom org policy: [customConstraints/custom.
restrictLbTlsVersion] : Only allow SSL policy resources to be created or
updated if the minimum TLS version is 1.2 where this custom constraint
is enforced.

示例：创建一个限制条件，以将 TCP 健康检查端口限制为至少 1,024

以下示例创建一个自定义限制条件和政策，以将 TCP 健康检查端口号限制为至少 1024。

在开始之前，您需要了解以下内容：

您的组织 ID
项目 ID

gcloud

使用以下信息创建 enforceTCPHealthCheckPort1024.yaml 限制条件文件：

name: organizations/ORGANIZATION_ID/customConstraints/custom.enforceTCPHealthCheckPort1024
resource_types:
– compute.googleapis.com/HealthCheck
condition: "resource.tcpHealthCheck.port >= 1024"
method_types:
– CREATE
– UPDATE
action_type: ALLOW
display_name: Only TCP HealthCheck Port >= 1024 Allowed.
description: Prevent TCP health checks on well-known ports.

设置自定义限制条件。

gcloud org-policies set-custom-constraint enforceTCPHealthCheckPort1024.yaml

创建一份 enforceTCPHealthCheckPort1024-policy.yaml 具有以下信息政策文件。在此示例中，我们在项目级层强制执行此限制条件，但您也可以在组织或文件夹级层设置此限制条件。请将 PROJECT_ID 替换为您的项目 ID。
```
name: projects/PROJECT_ID/policies/custom.enforceTCPHealthCheckPort1024
spec:
  rules:
  – enforce: true
```

强制执行该政策：

gcloud org-policies set-policy enforceTCPHealthCheckPort1024-policy.yaml

尝试在禁止使用的 80 端口上创建 TCP 健康检查，以测试此限制条件。

gcloud compute health-checks create tcp my-tcp-health-check \
    --project=PROJECT_ID \
    --region=us-central1 \
    --port=80 \
    --check-interval=5s \
    --timeout=5s \
    --healthy-threshold=4 \
    --unhealthy-threshold=5 \

输出类似于以下内容：

ERROR: (gcloud.compute.healthChecks.create) Could not fetch resource:
– Operation denied by custom org policies: [customConstraints/custom.enforceTCPHealthCheckPort1024]: Only TCP HealthCheck Port >= 1024 Allowed.
