Security
Secure your SUDO command
As SUDO is the key to your entire system, you should consider making it secure by require login by 2FA and your password. We are using the Google Authenticator PAM module for this.
Basics
Basic stuff and where to start Building.
Docker
CT or VM as your Docker host?
The VM clearly wins in terms of flexibility and security. The KVM VM is much better isolated from the host than the CT, can have full root rights, use features such as GPU pass-through and supports live migration.
Basics
Docker + Dockge on a Alpine VM
Make it small, use Alpine images. The smallest of them all is probably Alpine. I also included notes on Dockge and Portainer. For most of my VM apps Alpine is more than enough. It's small because it's lacking the bloat from GNU.

Ansible - Update All Nodes
Use Ansible to ensure that your nodes, VMs, and containers (CTs) are always up-to-date. You can create multiple playbooks and execute them with a single command or through a script.

A Docker based HA Pi-hole 6
This is a follow-up version of my post High Availability Pi-hole 6.
Basics
My New Lab – ZFS
ZFS is the new normal and replaces the RAID card generation. Why - our disks are too big and the problems with bit rot had to be addressed. After the release of the code as open source in 2001 it quickly moved into MacOS, FreeBSD and Linux. This is a guid for Proxmox users. #zfs

My New Lab
As we have moved, I need to downsize my lab drastically. I will create a series of posts how I create my new lab. Not only will I lower the number of servers but also use smaller machines, NUCs- and SFF-machines. As I need to do a lot of travelling, this will take a long time to get ready.

Sometimes you need a small desktop on the cluster to do stuff. Alpine is a pure Linux OS, it's tiny. Adding a desktop, and it's there, a lightweight, minimalistic and customizable Linux experience in a VM. It uses Open RC, not Systemd.
