exec

# Running commands Every `exec` call runs your command with bash in a **Linux container**. The durable object starts the container, and a small daemon in it, `computerd`, runs the command. ## What's installed - Debian, with `bash`, `git`, `curl` and the usual core tools. - Node.js 22 and `npm`. - Anything else can be installed with `apt-get` or `npm`. It lasts until the container stops. ## Network The container has direct network access, so `npm install`, `git clone` and `curl` work. ## Files - `/workspace` in the container is the workspace. `cwd` defaults to it. - The durable object's storage holds the authoritative copy. Before each call, changes made outside the container are pushed into `/workspace`. After the call, changes made in the container are pulled back. Something written outside `/workspace` stays in the container and isn't saved. - `/workspace/.agents/skills` (where this file lives) is a read-only copy of files shipped with the Worker. Changes you make there in the container are dropped when the call ends. ## Things to know - The first call is slow, because the container has to boot. Later calls reuse it while it stays up. - A container that stops loses everything outside `/workspace`, including installed packages. Reinstall rather than assume they're still there. - Every file under `/workspace` is synced back to storage after each call. This example keeps no paths on the container's local disk, so a large `node_modules` or build folder under `/workspace` slows every call down. Put throwaway output in `/tmp`.
