Another midnight catches me tinkering away at my own little cloud on the Internet. Since renting these 6 machines in Hetzner I’ve been literally hacking away for the past month on setting things up fully automated (that means also dns-01 challenges for all my domains automated with Ansible + FreeIPA for the core services, DNS included and tightening up security).
Out of all 6 machines, given 6TB per machine accumulated 36TB on top of which I put a few volumes of Gluster, two of them as “backup” and “ha-vms-root-fs” as I called it. Understandably, one is for (local, fast recovery) backups, doh, one is to host HA VMs declared as “resources” in Proxmox so the cluster takes care of making them HA if one machine fails). The one for backups in addition to TLK (TurnKey Linux) which provides the “tlkbam-backup” cron.

For the past few years I’ve been paying around €60/month at Google Cloud to host the equivalent of 4 cores and 8 GB of RAM in total on all my instances. Recently I converted my home i7-3770 to an Proxmox based server and found it super simple to work with it. Through a combination of No-IP, DNS CNAMEs and an HAproxy instance forwarded through my router I was able to get many applications easily installed (and backed-up to S3 through TurnKeyLinux TKLBAM/backup which runs Duplicity) around every single day. So much for complexity as in about 3 days I had pretty much everything up (Nexus, Go.CD and agents, this blog, Mattermost, Nextcloud, etc.)
In the past 3 days I rediscovered Hetzner. I knew them for a long time but I wasn’t so keen on renting “dedis” (dedicated servers). Up until I discovered their server auction going around the €30 per i7-3770 with 2x3TB of HDD and 32GB of RAM.
Initially I just fooled around and played around with 1 machine and the “installimage” script, trying out to see if it’s easy to set-up Debian 10 and PVE. It went smooth. Then I explored the networking part, trying to see if I could get an private subnet on the same VM to be routed in the so-called “single IP, routed configuration” that Proxmox suggests.
