LABCRAFT

Files for homelab provisioning and maintenance operations of my personal proxmox cluster for self-hosted services, application deployment environment and playhouse :)

ARCHITECTURE

The machine runs proxmox cluster with vm's and container above it

subgraph pokelab
direction TB
A[castleterra\n the proxmox host]
B[wailord\n docker host for self-hosted services]
C[espeon\n dns server]
D[umbreon \n second dns server]
E[staraptor\n web server for external reverse proxy]
G[arcanine\n wireguard host]
I[dittup\n pbs host for backups]
A --> B & C & D & E & G & I
end

NETWORKING

some services are exposed to the internet via HTTPS reverse proxy with nginx

DISKS MANAGEMENT

Containers and virtual machines's rootfs disk is located in the local-lvm volume on the nvme disk. all the volumes are backuped in the other hard drive from pbs

	end

BACKUPS

Backups are made with the use of PBS in snapshot mode, every night at 21:00 for all containers and virtual machines, one of the 2 hard drives is dedicated to this purpose, only the last 5 backups are maintained

for big containers stop mode is used instead, see this for reference
