About Network Multitool

Network Multitool is a multi-architecture utility image for container and network testing and troubleshooting. This Docker Hardened Image is based on Alpine Linux and packages a broad set of networking tools together with a minimal nginx web server to make it easy to run tests, capture packets, and serve test content.

The container includes tools for DNS inspection, HTTP testing, packet capture, route tracing, and basic system utilities. nginx runs by default on ports 80 and 443, allowing you to quickly validate HTTP/HTTPS behavior from other containers or hosts.

• Web server included: nginx runs by default on ports 80 and 443 (customizable via environment variables)
