+你可以通过为名字空间设置标签来强制实施 [Pod 安全标准](/zh/docs/concepts/security/pod-security-standards)。

+- Ensure the `PodSecurity` [feature gate](/docs/reference/command-line-tools-reference/feature-gates/#feature-gates-for-alpha-or-beta-features) is enabled.

+- 确保 `PodSecurity` [特性门控](/zh/docs/reference/command-line-tools-reference/feature-gates/#feature-gates-for-alpha-or-beta-features)已被启用。

+## Requiring the `baseline` Pod Security Standard with namespace labels

+## 通过名字空间标签来要求实施 `baseline` Pod 容器标准
+
+<!--
+This manifest defines a Namespace `my-baseline-namespace` that:
+
+- _Blocks_ any pods that don't satisfy the `baseline` policy requirements.
+- Generates a user-facing warning and adds an audit annotation to any created pod that does not
+  meet the `restricted` policy requirements.
+- Pins the versions of the `baseline` and `restricted` policies to v{{< skew latestVersion >}}.
+-->
+下面的清单定义了一个 `my-baseline-namespace` 名字空间，其中
+
+- *阻止*任何不满足 `baseline` 策略要求的 Pods；
+- 针对任何无法满足 `restricted` 策略要求的、已创建的 Pod 为用户生成警告信息，
+  并添加审计注解；
+- 将 `baseline` 和 `restricted` 策略的版本锁定到 v{{< skew latestVersion >}}。
+
+```yaml
+apiVersion: v1
+kind: Namespace
+metadata:
+  name: my-baseline-namespace
+  labels:
+    pod-security.kubernetes.io/enforce: baseline
+    pod-security.kubernetes.io/enforce-version: v{{< skew latestVersion >}}
+
+    # 我们将这些标签设置为我们所 _期望_ 的 `enforce` 级别
+    pod-security.kubernetes.io/audit: restricted
+    pod-security.kubernetes.io/audit-version: v{{< skew latestVersion >}}
+    pod-security.kubernetes.io/warn: restricted
+    pod-security.kubernetes.io/warn-version: v{{< skew latestVersion >}}
+```

+## Add labels to existing namespaces with `kubectl label`

+## 使用 `kubectl label` 为现有名字空间添加标签
+
+{{< note >}}
+<!--
+When an `enforce` policy (or version) label is added or changed, the admission plugin will test
+each pod in the namespace against the new policy. Violations are returned to the user as warnings.
+-->
+在添加或变更 `enforce` 策略（或版本）标签时，准入插件会测试名字空间中的每个
+Pod 以检查其是否满足新的策略。不符合策略的情况会被以警告的形式返回给用户。
+{{< /note >}}
+
+<!--
+It is helpful to apply the `--dry-run` flag when initially evaluating security profile changes for
+namespaces. The Pod Security Standard checks will still be run in _dry run_ mode, giving you
+information about how the new policy would treat existing pods, without actually updating a policy.
+-->
+在刚开始为名字空间评估安全性策略变更时，使用 `--dry-run` 标志是很有用的。
+Pod 安全性标准会在 _dry run（试运行）_
+模式下运行，在这种模式下会生成新策略如何处理现有 Pod 的信息，
+但不会真正更新策略。
+
+```shell
+kubectl label --dry-run=server --overwrite ns --all \
+    pod-security.kubernetes.io/enforce=baseline
+```
+
+<!--
+### Applying to all namespaces
+-->
+### 应用到所有名字空间
+
+<!--
+If you're just getting started with the Pod Security Standards, a suitable first step would be to
+configure all namespaces with audit annotations for a stricter level such as `baseline`:
+-->
+如果你是刚刚开始使用 Pod 安全性标准，一种比较合适的初始步骤是针对所有名字空间为类似
+`baseline` 这种比较严格的安全级别配置审计注解。
+
+```shell
+kubectl label --overwrite ns --all \
+  pod-security.kubernetes.io/audit=baseline \
+  pod-security.kubernetes.io/warn=baseline
+```
+
+<!--
+Note that this is not setting an enforce level, so that namespaces that haven't been explicitly
+evaluated can be distinguished. You can list namespaces without an explicitly set enforce level
+using this command:
+-->
+注意，这里没有设置 enforce 级别，因而没有被显式评估的名字空间可以被识别出来。
+你可以使用下面的命令列举那些没有显式设置 enforce 级别的名字空间：
+
+```shell
+kubectl get namespaces --selector='!pod-security.kubernetes.io/enforce'
+```
+
+<!--
+### Applying to a single namespace
+-->
+### 应用到单个名字空间
+
+<!--
+You can update a specific namespace as well. This command adds the `enforce=restricted`
+policy to `my-existing-namespace`, pinning the restricted policy version to v{{< skew latestVersion >}}.
+-->
+你也可以更新特定的名字空间。下面的命令将 `enforce=restricted` 策略应用到
+`my-existing-namespace` 名字空间，将 restricted 策略的版本锁定到 v{{< skew latestVersion >}}。
+
+```shell
+kubectl label --overwrite ns my-existing-namespace \
+  pod-security.kubernetes.io/enforce=restricted \
+  pod-security.kubernetes.io/enforce-version=v{{< skew latestVersion >}}
+```
