DIY CDN

This is a Rails app that will eventually power my tiny DIY content distribution network. Follow along if you'd like.

setting up a new cache node

• create proxy in cdn app
• create dns entry
• create vps
• curl -H 'Authorization: Bearer <proxy api key>' https://cdn.hostname/setup | sudo bash

scripts

• update one-minute cron, update certificates and config with last-updated-at. if there are updates, extract new certificates file, restart nginx

Changelog

Switched to production LE and set up corastreetpress.com. Everything seems to be working as expected.

2018-08-26

App can now set up latency-based A and AAAA records for sites

Next steps:

• Use the last_seen_at Proxy attribute to pull proxies out of rotation that don't check in
• Switch to production LE & set up a real site

2018-08-25

These things are now working:

• creating or updating a site's domain list will generate a LetsEncrypt certificate
• nginx config generation
• setup script (install nginx, create update curl | bash shim, set up cron)
• update script (download certificates and nginx config, restart nginx)
• update script is a server-controlled noop unless a site or proxy has updated since the certificates zipfile was last downloaded

Next steps:

• Switch to production LetsEncrypt
• Teach app how to set up proxies as geo-latency A and AAAA records for labels in domain_list for each site
• Set up a real site

TODO

• log rotate + remote_syslog2
• coordinate proxy admin with capistrano
• investigate SSH certificate authority
