-
-The **Container Network Policy** section provides packet flow metrics for
-your application's Kubernetes namespace. This section has the following
-prerequisites:
-
-- Your project contains at least one [environment](../../../ci/environments/index.md)
-- You've [installed Cilium](../../project/clusters/protect/container_network_security/quick_start_guide.md#use-the-cluster-management-template-to-install-cilium)
-- You've configured the [Prometheus service](../../project/integrations/prometheus.md#enabling-prometheus-integration)
-
-If you're using custom Helm values for Cilium, you must enable Hubble
-with flow metrics for each namespace by adding the following lines to
-your [Cilium values](../../project/clusters/protect/container_network_security/quick_start_guide.md#use-the-cluster-management-template-to-install-cilium):
-
-```yaml
-hubble:
-  enabled: true
-  metrics:
-    enabled:
-      - 'flow:sourceContext=namespace;destinationContext=namespace'
-```
-
-The **Container Network Policy** section displays the following information
-about your packet flow:
-
-- The total amount of the inbound and outbound packets
-- The proportion of packets dropped according to the configured
-  policies
-- The per-second average rate of the forwarded and dropped packets
-  accumulated over time window for the requested time interval
-
-If a significant percentage of packets is dropped, you should
-investigate it for potential threats by
-examining the Cilium logs:
-
-```shell
-kubectl -n gitlab-managed-apps logs -l k8s-app=cilium -c cilium-monitor
-```
-
-## Container Network Policy management
-
-> [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/3328) in [GitLab Ultimate](https://about.gitlab.com/pricing/) 13.1.
-
-The **Threat Monitoring** page's **Policy** tab displays deployed
-network policies for all available environments. You can check a
-network policy's `yaml` manifest, its enforcement
-status, and create and edit deployed policies. This section has the
-following prerequisites:
-
-- Your project contains at least one [environment](../../../ci/environments/index.md)
-- You've [installed Cilium](../../project/clusters/protect/container_network_security/quick_start_guide.md#use-the-cluster-management-template-to-install-cilium)
-
-Network policies are fetched directly from the selected environment's
-deployment platform. Changes performed outside of this tab are
-reflected upon refresh.
-
-By default, the network policy list contains predefined policies in a
-disabled state. Once enabled, a predefined policy deploys to the
-selected environment's deployment platform and you can manage it like
-the regular policies.
-
-Note that if you're using [Auto DevOps](../../../topics/autodevops/index.md)
-and change a policy in this section, your `auto-deploy-values.yaml` file doesn't update. Auto DevOps
-users must make changes by following the
-[Container Network Policy documentation](../../../topics/autodevops/stages.md#network-policy).
-
-### Changing enforcement status
-
-To change a network policy's enforcement status:
-
-- Click the network policy you want to update.
-- Click the **Edit policy** button.
-- Click the **Policy status** toggle to update the selected policy.
-- Click the **Save changes** button to deploy network policy changes.
-
-Disabled network policies have the `network-policy.gitlab.com/disabled_by: gitlab` selector inside
-the `podSelector` block. This narrows the scope of such a policy and as a result it doesn't affect
-any pods. The policy itself is still deployed to the corresponding deployment namespace.
-
-### Container Network Policy editor
-
-> [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/3403) in [GitLab Ultimate](https://about.gitlab.com/pricing/) 13.4.
-
-You can use the policy editor to create, edit, and delete policies.
-
-- To create a new policy, click the **New policy** button located in the **Policy** tab's header.
-- To edit an existing policy, click **Edit policy** in the selected policy drawer.
-
-The policy editor only supports the [CiliumNetworkPolicy](https://docs.cilium.io/en/v1.8/policy/)
-specification. Regular Kubernetes [NetworkPolicy](https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.19/#networkpolicy-v1-networking-k8s-io)
-resources aren't supported.
-
-The policy editor has two modes:
-
-- The visual _Rule_ mode allows you to construct and preview policy
-  rules using rule blocks and related controls.
-- YAML mode allows you to enter a policy definition in `.yaml` format
-  and is aimed at expert users and cases that the Rule mode doesn't
-  support.
-
-You can use both modes interchangeably and switch between them at any
-time. If a YAML resource is incorrect, Rule mode is automatically
-disabled. You must use YAML mode to fix your policy before Rule mode
-is available again.
-
-Rule mode supports the following rule types:
-
-- [Labels](https://docs.cilium.io/en/v1.8/policy/language/#labels-based).
-- [Entities](https://docs.cilium.io/en/v1.8/policy/language/#entities-based).
-- [IP/CIDR](https://docs.cilium.io/en/v1.8/policy/language/#ip-cidr-based). Only
-  the `toCIDR` block without `except` is supported.
-- [DNS](https://docs.cilium.io/en/v1.8/policy/language/#dns-based).
-- [Level 4](https://docs.cilium.io/en/v1.8/policy/language/#layer-4-examples)
-  can be added to all other rules.
-
-Once your policy is complete, save it by pressing the **Save policy**
-button at the bottom of the editor. Existing policies can also be
-removed from the editor interface by clicking the **Delete policy**
-button at the bottom of the editor.

-### Configuring Network Policy Alerts
-
-> - [Introduced](https://gitlab.com/groups/gitlab-org/-/epics/3438) and [enabled by default](https://gitlab.com/gitlab-org/gitlab/-/issues/287676) in [GitLab Ultimate](https://about.gitlab.com/pricing/) 13.9.
-> - The feature flag was removed and the Threat Monitoring Alerts Project was [made generally available](https://gitlab.com/gitlab-org/gitlab/-/issues/287676) in GitLab 14.0.
-
-You can use policy alerts to track your policy's impact. Alerts are only available if you've
-[installed](../../clusters/agent/repository.md)
-and [configured](../../clusters/agent/index.md#create-an-agent-record-in-gitlab)
-a Kubernetes Agent for this project.
-
-There are two ways to create policy alerts:
-
-- In the [policy editor UI](#container-network-policy-editor),
-  by clicking **Add alert**.
-- In the policy editor's YAML mode, through the `metadata.annotations` property:
-
-  ```yaml
-  metadata:
-    annotations:
-      app.gitlab.com/alert: 'true'
-  ```
-
-Once added, the UI updates and displays a warning about the dangers of too many alerts.
