The Rust Programming Handbook

So far, we’ve focused on Dockerizing a single Rust application. However, many real-world applications are more complex, consisting of multiple interconnected services. For example, your Rust web application might need a database (such as PostgreSQL), a caching service (such as Redis), or other backend microservices. Managing each of these as separate Docker containers with individual docker run commands, along with their networking and data persistence, can quickly become cumbersome and error-prone.
It’s important to understand, however, that Compose is fundamentally a single-host tool. It is designed for managing multiple containers on one machine, which is perfect for development, testing, and simple production environments.
It does not handle multi-host deployments, automatic scaling across servers, or self-healing (e.g., restarting a container on a different machine if one server fails). For those more complex...
