Container on browser

In the container, the workspace is mounted at /workspace and you can compile and run hello.c file.

root@localhost:/# ls /workspace/
LICENSE  hello.c
root@localhost:/# gcc /workspace/hello.c
root@localhost:/# ./a.out
Hello, world!

Container

This will launch the following container.

FROM debian:sid-slim
RUN apt-get update && apt-get install -y gcc

The workspace is visible at /workspace in the container.

Note that this extension doesn't require remote container. This extension downloads the Wasm image converted from the container and runs it in the WebAssembly VM in your browser.

HTTP(S) networking is available in the contaienr with restrictions by the browser (CORS-restricted and no control over Forbidden headers). (see also the project README).

You can customize settings.json if you want to load other containers.
