Lower power usage of my homelab
For now more than a year, I have my homelab running all day long.
With my homelab, I can create VM's, launch applications on docker in seconds, get my website online from my home, ...
I realized recently that all my applications that need to be online should use 1% of my CPU at the time.
The others that can use more CPU don't need to be online all the time. So I decided some weeks ago to reduce my electricity usage by migrating all my necessary online apps to my raspberry pi.
I have on the Raspberry Pi:
- Nginx Proxy Manager
- pihole
- gemini caspule
- web proxy for my capsule
- heimdall
So what is laying on my homelab ?
- Plex
- file sharing with my relatives
- game servers (like minecraft)
- Gaming Windows VM
Now my homelab only has apps that I don't really need to run all the time.
But... It could be smarter. You see, sometimes, I would like to listen musics or watch movies from Plex, download some files or game on my Windows VM remotely. I think this could be my Graal.
After an eternity of thinking how I could do that (it's wrong!), I found an answer, the holy answer : WakeOnLan. Just execute a command and your stopped server is now starting <3
Of course, not all motherboard has this capability, but mine has it! What a luck!
Finally, I can VPN to my router, SSH to my pi and execute this cute little command wakeonlan mac:address and boom! Server started, ready for work (or gaming).
