A deployment checklist for securely deploying Docker containers on Linux-based hosts.
Docker Secure Deployment Guidelines is a comprehensive checklist for hardening Docker container deployments to mitigate security risks. It addresses common vulnerabilities and misconfigurations that can expose containers and hosts to attacks, offering actionable recommendations based on industry best practices. The guidelines focus on Linux Docker containers on Linux-based hosts using Docker 1.4.0.
System administrators, DevOps engineers, and security professionals responsible for deploying and managing Docker containers in production environments. It's particularly valuable for teams needing to secure containerized applications against common attack vectors.
Developers choose this over generic security advice because it provides Docker-specific, actionable hardening steps with concrete command examples. Its defense-in-depth approach covers everything from image security to kernel hardening, making it a comprehensive reference for securing Docker deployments.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Covers multiple layers from image integrity to kernel hardening, following a defense-in-depth approach as emphasized in the philosophy, ensuring no major attack vector is overlooked.
Provides specific Docker command-line options and configurations, such as using --security-opt for SELinux or --cap-drop to reduce capabilities, making it practical for immediate implementation.
Cites experts like Jérôme Petazzoni and Daniel J Walsh, along with Docker documentation, adding credibility and allowing users to explore sources for deeper understanding.
Prioritizes minimal privileges, isolation, and regular audits, as stated in the philosophy, which is a robust strategy for reducing attack surfaces in container deployments.
Based on Docker 1.4.0 from 2014, many features and best practices have evolved, so recommendations like those for cryptographic signatures may be incomplete or obsolete for current versions.
Only applies to Linux Docker containers on Linux hosts, as the README admits, excluding Windows containers or cloud-native platforms, reducing its relevance for heterogeneous environments.
Offers a checklist without automation tools, requiring manual implementation which can be error-prone and time-consuming compared to integrated security solutions or scanning tools.
Acknowledges that key security features like user namespaces and seccomp are works in progress or require using the deprecated LXC driver, limiting their practical application in modern setups.
