Kubernetes operators often struggle to gain visibility into Cilium-based networking, causing delays when diagnosing policy issues and connectivity problems. This skill provides a guided set of workflows to observe traffic, validate policies, and troubleshoot networking efficiently.
Use the k8s-cilium skill to begin observing and troubleshooting Cilium networks in your Kubernetes cluster. Quick Start: - Confirm Cilium is installed with cilium_detect_tool() and check status with cilium_status_tool(); - Query active flows with hubble_flows_query_tool() for a given namespace; - List policies with cilium_policies_list_tool(namespace) and inspect details with cilium_policy_get_tool(name, namespace).

To troubleshoot Cilium network policy issues, you can use built-in workflows to list policies with cilium_policies_list_tool and inspect details with cilium_policy_get_tool to detect misconfigurations and validate CiliumNetworkPolicy behavior.
You can observe Kubernetes pod traffic by querying active L2-L7 flow data across namespaces and pods using the hubble_flows_query_tool, which provides cluster-wide visibility into connectivity.
You need access to a Kubernetes cluster with Cilium and Hubble installed, allowing you to detect the installation with cilium_detect_tool and check status with cilium_status_tool before validating policies.
Unexpected traffic blocking often stems from CiliumNetworkPolicy misconfigurations; you can reproduce the issue by observing L2-L7 flow data and inspecting policy details to identify the restrictive rule.
The best way to gain cluster-wide visibility into Cilium networking is to observe traffic and analyze flow data across Kubernetes workloads using Hubble, validating policies and troubleshooting connectivity efficiently.
