cilium/hubble-ui repository overview

⁠Hubble UI

Hubble UI is open source user interface for Cilium Hubble⁠.

⁠Installation

Hubble UI is installed as part of hubble, please see Hubble Getting Started Guide⁠ for details.

⁠Why Hubble UI?

Troubleshooting microservices application connectivity is a challenging task. Simply looking at "kubectl get pods" does not indicate dependencies between each service or external APIs or databases.

Hubble UI enables zero-effort automatic discovery of the service dependency graph for Kubernetes Clusters at L3/L4 and even L7, allowing user-friendly visualization and filtering of those dataflows as a Service Map.

See Hubble Getting Started Guide⁠ for details.

⁠Development

⁠Backend

If you want to point frontend to backend deployed into minikube, then just do next port forward: kubectl port-forward -n kube-system deployment/hubble-ui 8081.

Otherwise, if you want to change something in Go backend there are additional steps:

1. Go to backend directory cd ./backend, execute ./ctl.sh run, wait build and server running
2. In another terminal go to server directory with envoy config cd ./server and execute envoy -c ./envoy.yaml (envoy must be installed)
3. In another terminal do port forward to hubble-relay kubectl port-forward -n kube-system deployment/hubble-relay 50051:4245

⁠Frontend

1. Install deps npm install
2. Start development server npm run watch
3. Open http://localhost:8080⁠
