• Access to proxy is whitelisted by the public IP of the system starting the proxy
• Based on squid proxy

Requirements

• DigitalOcean account and API token
• curl
• jq v1.3+

Tested on Ubuntu 14.04.5 LTS with

• curl v7.35.0
• jq v1.3

where <command> can be one of the following commands

• start:

  Start the proxy droplet (creates a new droplet)

• stop:

  Stop the proxy droplet (deletes the droplet)

Ideas

• Verbose mode
• Write bootstrap.sh script that pulls droplet-blueprint.json and droplet-init.sh from GitHub
• Self destruction
• Command to update IP whitelist
• Attach iftop
• Attach access log
• Support different hosting providers (e.g. Linode)
• Support different proxy software (e.g. Tinyproxy)
• Consider porting to Python 3 to for easier distribution through PIP

This script was improved by some ideas and snippets from the gist by Henrik Feldt that showed me how to write a more proper shell script. Thank you Henrik.
