About:
Cilium CLI is a command-line utility designed to streamline the installation, management, and troubleshooting of Cilium within Kubernetes environments. It provides operators with direct access to the Hubble observability layer and Cilium's networking features. This tool simplifies complex operations, making it essential for maintaining secure and performant cloud-native infrastructure.
Key Features:
  • Automated installation and upgrade of Cilium on Kubernetes clusters
  • Integrated access to Hubble for deep network observability and flow visualization
  • Built-in troubleshooting commands to diagnose connectivity and policy issues
  • Support for managing Cilium Service Mesh and Cluster Mesh deployments
Use Cases:
  • Deploying Cilium CNI on new or existing Kubernetes clusters
  • Debugging network connectivity issues between microservices
  • Visualizing service dependencies and traffic flows in real-time
  • Managing multi-cluster service mesh configurations
Alternatives:
  • kubectl – Generic k8s CLI; lacks Cilium-specific abstractions and observability features.
  • Helm – Used for initial installation, but less effective for runtime troubleshooting and observability.
