net-debug

Description

Assorted network debugging goodies, like tcpdump, socat/websocat, iperf, nmap, nslookup, dig, tcpreplay, and ping/traceroute, all packaged in a self-contained Docker image. The intended use is to sideload the container as a sidecar to Kubernetes pods in order to debug network reachability and performance issues.
