WWT Squid Proxy Server

This repository contains setup for a backend component of the AAS WorldWide Telescope web services.

In particular, the core WWT operates a web proxy to allow the interactive web client to fetch data from remote servers in the cases when the web browser would prohibit direct access, because of:

• CORS restrictions
• insecure content (http://) being loaded from a secure origin (https://)

This web proxy is implemented as a Docker container running a specially configured version of the Squid proxy server. This proxy is itself reverse-proxied through an Azure Application Gateway so that everything can be served from the core domain.

Building / Installation

This isn't really software that "install" yourself. The output artifact of this repository is a Docker image that you obtain with the command:

docker build -t aasworldwidetelescope/proxy:latest .

The main purpose of this pipeline is to automate the build and publication of this image through the azure-pipelines.yml file. The image ultimately emerges as aasworldwidetelescope/proxy. A webhook is configured there to update the running service on Azure.
