Export/Import of ZFS Pools
Upgraded your server, but you need your old ZFS pools. How to import your olde files. Sometimes it's better to reinstall the Proxmox rather than trying to fix a broken system.
Build
To build a home lab on Linux with Docker and Dockge/Portainer. Self hosting servers, services, websites and more. Using Ubuntu and Proxmox. Backed by TrueNAS.

SUDO – Superuser do
Adding users to the sudo/doas/wheel group is a straightforward way to grant root-like access, especially in a multi-user environment where multiple users need administrative privileges. Is it wise – no, is it needed – sometimes. See also the Fail2ban section.

Proxmox Copy & Paste
How do you make "Copy and Paste" work in your VM.
Docker
Docker Swarm Mode
Container orchestration the easy way. Swarm mode is an advanced feature for container orchestration. Use Swarm mode if you intend to use Swarm as a production runtime environment. Docker Swarm mode is built into the Docker Engine. Docker Swarm mode is similar to K3s or even K8s, but it's lighter.

Photon OS
Sometimes it's a better to have an easy-to-use system rather than one with everything. We need a secure VM and that's why we run Proton OS. Using the recommendations of the KSPP (Kernel Self-Protection Project), the Photon OS Linux Kernel is secure from the start.
Build
Cloud Images & Cloud-init
One of the supporting pillars of virtualization is the use of Cloud-Init and Cloud Images. Setting up VMs is easy and fast. The process is easy to automate and adapt to CI/CD.
Build
Proxmox LXC PBS
Proxmox Backup Server is flexible and can be installed on any device running Debian, a VM or a LXC. Here I show my Proxmox LXC setup. Having PBS on the PVE is making use of the large and fast SSD ZFS RAID 10 storage.
Tools
Clearing old Disks – Wipe them
Before re-using any old disk, I do like to wipe them of data. Before removing the disk from the node, we wipe it clean. Now they are ready to store for later use or passed to a new owner with an old server.
Ricing
Make BASH nicer, make it shine.
As I as many of you spend most of my time in a terminal, why not make it shine a little. As everyone know, ZSH is easy to rice, but you can almost as easy rice your BASH shell.
Build
ShredOS – Disk Eraser
ShredOS uses the nwipe is a program that will securely erase the entire contents of disks. It can wipe a single drive or multiple disks simultaneously. It can operate as both a command line tool without a GUI or with a ncurses GUI.
Basics
Server Monitoring with Beszel
Beszel is a lightweight server monitoring platform that includes Proxmox and Docker statistics, historical data, and alert functions. It has a nice web interface, simple configuration, and is ready to use out of the box. It supports automatic backup, multi-user, OAuth authentication, and API access.
Build
TrueNAS VM PBS
Proxmox Backup Server is flexible and can be installed on any device running Debian, a VM or a LXC. Here I show my TrueNAS VM setup, as my main production has moved to my new TrueNAS CE box. Having PBS on the NAS is making use of the large and fast SAS ZFS RAID 10 storage.
