Building, Deploying and Observing WASM Apps

The summary is as follows: The Docker + WASM Technical Preview is a project that combines the benefits of WebAssembly (WASM) and Docker to create a powerful platform for modernized web applications. WASM is a binary instruction format for a stack-based virtual machine, designed to run in modern web browsers, while Docker provides a way to package, deploy, and manage applications. The technical preview aims to explore the potential of running WASM applications inside Docker containers, offering high-performance, portability, and security features. However, there are caveats, such as compatibility issues with traditional Linux containers and security vulnerabilities in early-stage development. To get started, developers can follow a tutorial that guides them through creating a TypeScript application, building it to a WASM module, writing a Dockerfile, and running the image. The project also aims to include observability capabilities using OpenTelemetry, allowing for metrics and tracing collection from the application.
