webify

Turn functions and commands into web services

For a real world example, see turning a Python function into a web service.

Overview

webify is a very basic CGI server which forwards all requests to a single script. A design goal is to be as zero-config as possible.

webify invokes your script and writes the request body to your process' stdin. Stdout is then passed back to the client as the HTTP response body.

If your script returns a non-zero exit code, the HTTP response status code will be 500.

Installation

webify is available from the project's releases page.

On macOS, it can also be installed via MacPorts:

sudo port install webify

Usage

# Make a web service out of `wc` to count the characters in the request body.
$ webify wc -c
2020/08/25 12:42:32 listening on :8080, proxying to wc -c

...

$ curl -d 'This is a really long sentence' http://localhost:8080
30

Official Docker image

The official Docker image is beefsack/webify.

It can be configured using the following environment variables:

• ADDR - the address to listen on inside the container, defaults to :80
• SCRIPT - the command to execute, defaults to /script

Mounting script and running official image

$ docker run -it --rm -p 8080:80 -v /path/to/my/script:/script beefsack/webify:latest
2020/08/25 04:27:46 listening on :80, proxying to /script

...

$ curl -d 'Some data' http://localhost:8080

Building a new image using official image as base

Create a Dockerfile like the following:

FROM beefsack/webify:latest
COPY myscript /script
