<ul><li>Applications were traditionally run on a host OS or inside VMs, leading to issues in replicating setups across different environments, a concerning challenge for amateur radio enthusiasts experimenting with various tools.</li><li>Docker, an open-source platform, offers lightweight deployment by packaging applications and dependencies into containers, ensuring consistent setups on devices like Raspberry Pi, cloud servers, and more. This method is beneficial for sharing setups and preventing conflicts.</li><li>Virtual Machines (VMs) remain relevant for tasks like running legacy software, OS testing, and isolation, but they require more resources and are slower compared to Docker. Each has its strengths, with Docker excelling in speed, portability, and efficiency.</li><li>Usage scenarios for Docker in ham radio include setting up APRS iGate, SDR applications, Winlink gateways, and automation scripts, providing ease in testing and sharing setups. Understanding when to use Docker versus VMs depends on the specific project requirements and system stability concerns.</li></ul>
