mitmproxy docker project

Goal I would like a tool that I run on my laptop that proxies website traffic. This would be both HTTP and HTTPS traffic. I would like to be able to use this tool to... 1. Match a URL, based on some separate configuration file (use REGEX) and if the URL matches.. 2. Modify the HTML of a website, so I see the modified HTML in my browser 3. Modify HTML to inject some javascript to the HTML. The javascript would be in a separate .JS file so the injection would be a <script src="/path/to/[login to view URL]"></script> 4. All of the above would be easily configurable for site to site, so that anyone can set up a new site easily 5. Need instructions for how to install and how to modify for the above. Deliverables Dockerfile and docker-compose with mitmproxy. Use the lightest docker-image you can. Documentation for how to install and use. If certificates are required for HTTPS sites, then supply documentation for how to do that. Use python3 whereever you need to use coding. Install dependencies via requirements.txt. Suggested file structure: PROJECT_FOLDER - Dockerfile - [login to view URL] - certificate - url_config-and-search-replace - site-config (if necessary, eg. host file entry) - javascripts/[login to view URL] - [login to view URL] Tools to use: - mitmproxy - docker - docker-compose - python3 - REGEX mitmproxy proxies traffic to a website. It has the capability to modify the original HTML with something else. docker and docker-compose helps make applications portable. Python is python. Wherever code needs to be done to manipulate anything (eg. search and replace etc), then use python for that.
