Wadm

As explained in Server-Side WebAssembly

wadm is the wasmCloud application deployment manager for declaring, deploying, linking, and monitoring application components.

wadm is the wasmCloud application deployment manager: a declarative YAML file describes components, capability providers, links, and scaling for an application. section 6.1

Hello World deployment

A Rust HTTP component is linked to the wasmCloud HTTP server through the wasi:http incoming-handler interface. The manifest assigns one component instance and exposes it at 127.0.0.1:8000; curl returns “Hello from Rust!”.

How Server-Side WebAssembly covers it

How deep it goes
Explains manifest structure and a complete build-deploy-test workflow, but does not descend into wadm internals.
Examples
Uses a Rust HTTP Hello World component, wadm.yaml, wash commands, deployment status output, and a curl response.
What you can do after
Operate/configure a wasmCloud application by building artifacts, deploying a manifest, checking status, and testing an HTTP endpoint.
How it connects
Connects wasmCloud components with HTTP servers, Wasmtime hosts, NATS lattices, WASI interfaces, and spreadscaler traits.
