A Docker and Kubernetes network troubleshooting container packed with networking tools for diagnosing connectivity, performance, and DNS issues.
Netshoot is a Docker container specifically designed for troubleshooting network issues in Docker and Kubernetes environments. It provides a comprehensive suite of networking tools, allowing users to diagnose problems without installing packages directly on hosts or application containers. By leveraging network namespaces, it can seamlessly integrate into existing container or host network stacks for effective debugging.
DevOps engineers, SREs, and platform engineers who manage and troubleshoot containerized applications in Docker and Kubernetes environments.
Developers choose Netshoot because it bundles a wide array of essential networking utilities into a single, portable container, eliminating the need to install tools on hosts or application containers. Its unique selling point is the ability to attach to any container, pod, or host network namespace, providing a 'swiss-army knife' for network diagnostics in modern infrastructures.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Bundles over 50 networking utilities like tcpdump, iperf, nmap, and specialized tools (e.g., grpcurl, fortio), covering packet analysis, performance testing, and service debugging as listed in the README.
Leverages Docker and Kubernetes network namespaces to attach to containers, pods, or hosts via commands like --net container:<name> or kubectl debug, enabling troubleshooting without modifying target environments.
Integrates with Kubernetes ephemeral containers, sidecar deployments, and has a dedicated kubectl plugin for easy pod and node debugging, as shown in the sample configurations.
Tools are built for various architectures, ensuring compatibility across different deployment environments, mentioned in the key features for broad use.
Tools like nsenter require running the container with --privileged flag, which poses security risks and may not be allowed in locked-down production clusters.
Including numerous packages increases image size, making it less efficient for quick, lightweight operations compared to minimal tool-specific containers.
The README provides use-cases but assumes familiarity with CLI networking tools, offering limited guidance for beginners on tool selection or interpretation.
