Hello Deno Service

Description

A simple Deno server intended to serve as an example of deploying a Deno application to Google Cloud Run.

Usage

After cloning the repository, start the server:

$ deno run --allow-net --allow-env src/index.js

Locally, this will run the server on http://localhost:8080.

To use the Docker container, run:

$ docker build -t app . && docker run -it --init -p 8080:8080 -e PORT=8080 app

Notes

1. The server reads from the PORT environment variable to determine which port to listen on. This is important because Google Cloud Run defines this variable and it's the only port that will be open.
2. Google Cloud Run also requires that the server listen on 0.0.0.0 because 127.0.0.1 is a loopback address with no external access.
3. Deno requires that the port value is a number and will throw an error otherwise.
