This is a fantastic walkthrough of implementing mTLS between Docker containers! 🎉 The clear explanations and practical examples provide a great foundation for understanding mutual authentication and encryption. I appreciate the step-by-step approach to set up both non-encrypted and encrypted communication, as well as the use of tcpdump for verification. The comparison to service meshes is insightful, highlighting how tools like Istio and Linkerd can streamline mTLS. Thanks for demystifying this crucial security concept in such an approachable way! 👏
