Reaching the server
The server is currently in a place where allocating a public IP is not possible, so:
internet ─▶ Cloudflare Tunnel ─▶ apps
me ─▶ Twingate ─▶ Proxmox / SSH
Currently running
Proxmox VE 8.1 with a few VMs and LXCs
Infrastructure
- Coolify: self hosted vercel to host my own applications.
- Umami: analytics for my websites
Tools
- YT-DLP: downloader for youtube videos
- Bento PDF: pdf tools
Experiments
I also experiment with open source self hosted apps once in a while. Recently, I tried hosting my instance of mattermost to replace slack.
The rack
Instead of buying a new or used rack, I built one from 2020 aluminium extrusions. The top is plywood I had lying around, cut to size, sanded, and finished with a clear protective coat. Caster wheels make it easy to move around.
Parts
- Depth: 800mm × 4
- Vertical: 450mm × 4 (+4 optional for extra support)
- Horizontal: 445mm × 6 (4 on top, 2 on the bottom)
- 8 inside corner joints
- 20–30 90° angle brackets (more = sturdier)
- ~50 bolt and nut sets
- 1 set of caster wheels
