Docker + Wasm + Wasm Workers Server (wws)

This repo showcases some functions you can write, taking advantage of Wasm Workers Server, on top of Docker Desktop, thanks to the containerd-wasm-shims project.

Build

Prerequisites for building this project:

• Docker, with Docker + Wasm support

In order to build this example, you just have to run on the root of this project:

$ make build

Running

Prerequisites for running this project: Docker Desktop 4.23.0 or later.

You can run the example:

$ make run

After that, you can target the different endpoints exposed by the Wasm Workers Server:

$ curl -s http://localhost:3000/user-generation-rust | jq
$ curl -s http://localhost:3000/user-generation-go | jq
$ curl -s http://localhost:3000/user-generation-js | jq
$ curl -s http://localhost:3000/user-generation-python | jq
$ curl -s http://localhost:3000/user-generation-ruby | jq

This example also showcases exposing a directory in the host to the WebAssembly guest. This example can be executed with:

$ make run-with-mount

You can reach the same endpoints, but you will notice that the attribute .some_file_contents of the produced JSON in all examples now is the content of tmp/file.txt from the host.

The only worker that is not able to read contents from the filesystem is the JS one, so you can only check it with the rest:

$ curl -s http://localhost:3000/user-generation-rust | jq
$ curl -s http://localhost:3000/user-generation-go | jq
$ curl -s http://localhost:3000/user-generation-python | jq
$ curl -s http://localhost:3000/user-generation-ruby | jq
