# kubernetes-network-tester

Tests Kubernetes pod-to-pod network connectivity using Prometheus and blackbox-exporter.

## Usage

Download from the [Releases][release] page, then run:

```

./kubernetes-network-tester \

  -numhosts 3

  -resolver $(kubectl get svc -n kube-system kube-dns -o jsonpath='{.spec.clusterIP}'):53 \

  checksvc1 checksvc2 checksvc3

```

This will create daemonsets and services named checksvc2, checksvc2, and

checksvc3. It will also create a Prometheus deployment and service named

'prometheus'.

The Prometheus configuration is designed to have every checksvc pod query

every checksvc pod. kubernetes-network-tester will exit with an error if it

can't validate every pod-to-pod connection via Prometheus before it times

out.
