deno_docker example fails with 'TypeError: Deno.writeAll is not a function'

[und-miller]

Copying the code verbatim from the docker example does not work.

Can be reproduced by:

1. Copy the code from https://github.com/denoland/deno_docker/tree/main/example
2. Run docker build -t app .
3. Run docker run -it --init -p 1993:1993 app
4. From another terminal run curl http://localhost:1993
5. Fails with the error below

error: Uncaught (in promise) TypeError: Deno.writeAll is not a function
      await Deno.writeAll(
                 ^

Also this fails the same way:

deno run -A --unstable https://deno.land/x/[email protected]/install.ts

any updates on this? we have the same issue

I ran into this. You can get past this by simply using this in the main.ts:

Deno.serve(
    { port: 1993, hostname: "0.0.0.0" }, 
    (_req) => new Response("Hello, world")
);

Seems to be related to a depreciation in 1.40 that was fully removed in 2.0.
