Deno 2.9 on Ubuntu 24.04 LTS

Deno is a modern, secure-by-default JavaScript and TypeScript runtime: built-in TypeScript support with no separate compile step, a single binary with no node_modules, and a permissions sandbox that blocks filesystem, network and environment access unless explicitly granted. This cloudimg image installs the official pinned Deno v2.9.2 release binary on Ubuntu 24.04 LTS, verified against a sha256 checksum.

Deno has no admin console or login, so this image ships a small demo HTTP API pre-deployed and running under systemd, proving the runtime is genuinely executing code on every request, a live server timestamp and a request counter that changes on each call. The systemd unit grants only --allow-net, scoped to the loopback address and port the demo binds, no filesystem, environment or subprocess access, demonstrating Deno's secure sandboxing model correctly. The demo is bound to loopback only, with nginx fronting it on port 80 and an unauthenticated health check endpoint for load balancers.

Deployed app code and any application data live on a dedicated 20 GiB Azure data disk, independent of the OS disk. The image ships with the latest security patches applied at build time and stays current through unattended upgrades. cloudimg provides 24/7 commercial support with a guaranteed 24 hour response SLA, separate from the upstream open source project.

Deno is MIT licensed, free and open source with no per-CPU or per-deployment fee.
