Since Vodafone's DS-Lite-Tunnel doesn't offer native IPv4 addresses (and many services incl. Github Actions & the Slack API don't speak IPv6 yet), I had to move my homepage, slack & telegram bots off my Raspberry Pi infrastructure and back to Digital Ocean.
Build & Deploy DigitalOcean Droplet
Using the golang api from godo, every push to this repository creates a custom Ubuntu 
I have a weekly cronjob running on one of my raspberry PIs which triggers this deployment after regenerating the SSL certificate (only valid for 10d) required by the various servers.
Every push to this repo will result in a new Droplet created at DigitalOcean => +$7 / month, tearing down and redeploying websites and bots while also updating DNS entries for *.ackerson.de.
Use git commit msg string snippet [skip ci] to avoid this.
