Netshoot
Netshoot is a Docker network troubleshooting toolkit and container image bundled with specialized utilities for DNS resolution, performance benchmarking, and TCP/IP packet inspection. It serves as a portable set of tools designed for diagnosing connectivity and routing issues within Docker and Kubernetes environments.
The project is distributed as a tool-aggregated container image that can be deployed as a debugging sidecar or an ephemeral runtime. It supports namespace-joined execution, allowing the toolkit to attach to the network namespace of another process to inspect traffic and diagnose communication from a specific perspective.
The suite covers a wide range of network diagnostic capabilities, including DNS resolution debugging, IP routing management, and port scanning. It provides tools for network performance measurement, packet traffic analysis, and connection testing across TCP, UDP, and gRPC protocols, as well as utilities for SMTP transaction testing and container resource monitoring.
Features
- Tool-Aggregated Images - Bundles a curated set of networking binaries into a single image for deployment as a sidecar or ephemeral container.
- Diagnostics - Launching a specialized toolset into a network namespace to troubleshoot communication failures for specific containers.
- Packet Capture Utilities - Provides capabilities to capture and inspect raw TCP/IP packets to diagnose communication failures.
- Ephemeral Diagnostics - Launches short-lived container instances to perform diagnostics and minimize resource overhead.
- Sidecar Containers - Deploys as a sidecar container to monitor and inspect traffic without modifying the target application image.
- Network Namespace Sharing - Attaches to the network namespace of another process to diagnose connectivity from a specific container's perspective.
- Connection Testers - Provides the capability to verify port availability and detect firewall blocks via TCP and UDP connection tests.
- DNS Management Tools - Provides a suite of utilities for verifying name resolution and managing IP routing tables.
- DNS Record Resolvers - Includes tools to query DNS servers for detailed record information and verify name resolution settings.
- Protocol Connectivity Diagnostics - Integrates specialized tools for TCP, UDP, DNS, and gRPC to validate connectivity across the network stack.

Star history
How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
