This is a simple, not-very-cleverly-named looking glass tool. Supports pinging and MTRing arbitrary addresses. Also supports dns lookup, nping (tcp-ping on port 80) and iperf3 client.

Simply running sudo docker run -d -p 8080:8080 malaiwah/lg will get you a container running this app under http on port 8080, in an rbash environment restricted to only running ping and mtr. You can also expose port 5201 (-p 5201:5201) to allow connections to the iPerf3 daemon.

You can use the "deployment.yaml" file as an example on how to deploy the looking glass as a sample k8s application
