Implementing Container Network Policies with Calico
Overview
Calico provides Kubernetes-native and extended network policy enforcement through its CNI plugin. This skill covers creating and auditing Calico NetworkPolicy and GlobalNetworkPolicy resources to implement pod-to-pod traffic control, namespace isolation, egress restrictions, and DNS-based policy rules using calicoctl and the Kubernetes API.
When to Use
- When deploying or configuring implementing container network policies with calico capabilities in your environment
- When establishing security controls aligned to compliance requirements
- When building or improving security architecture for this domain
- When conducting security assessments that require this implementation
Prerequisites
- Kubernetes cluster with Calico CNI installed
- Python 3.9+ with
kubernetesclient library - calicoctl CLI tool installed and configured
- kubectl access with RBAC permissions for network policy management
