go pip package builder

Building

Run

docker build -t <NAME> .

Running

Recommendation: Use cloud run, this repo has a cloudbuild yaml file that builds and deploys new versions after a push. It is convenient, and some features like isolation and scalability come alongside, see the notes section for more details.

But if you want to use it on a VM or local machine you can run:

docker run -p 8080:8080 <NAME>

This service is configured to quit after each request, for isolation needs, so using --restart=always is convenient.

For best results I recommend using a serverless/container orchestration platform, here I used Google Cloud Run.

Using

You can use from your browser, and sending the package name in the form, or using curl:

Make a HTTP request with the package name on the path:

curl localhost:8080/requests

Or a POST with a form:

curl localhost:8080/package.zip -F package=requests

If successful the response contains a zip file, so browsers download it afterwards, for your convenience.

Notes

The isolation is achieved by running this program on a serverless/container platform like Google Cloud Run, with concurrency set to 1. This server is made to kill itself after the first build, hence, the following request will be handled by a new instance.

To compensate we set the maximum instances to a bigger number, like 100, so this service can bear more activity.
