The migration was not just putting apps into pods. It was separating application workloads from the core infrastructure those workloads depend on.
June
The lab moved from scattered Docker hosts toward a k3s-based application platform. Kaveh and Thoma stopped being the center of the app world. Workloads moved into Kubernetes. The platform started to look more intentional.
But the important decision was what did not move into k3s.
DNS stayed in LXCs. PostgreSQL and MariaDB stayed external. Storage stayed on Zhongli. Backups stayed separate. Pangolin/Newt continued handling public access. Infisical handled secrets. Traefik handled internal .fndhome ingress. That separation kept the cluster from depending on itself for the things it needs to survive.
Kubernetes was not the boss fight. Storage, secrets, databases, ingress, and rollback were the boss fight.

Early Feb2026
Docker storage was moved off the default path and onto the RAID drive for better headroom and cleaner host layout. Beszel kept working, containers kept running, and the actual Docker move was fine.
Dockhand quietly stopped reporting. The issue was not Docker itself. It was the third-party agent installed by a one-line curl-to-bash script.
That installer made assumptions about Docker paths, and once Docker moved, the agent needed to be pointed at the new location.
Beszel has been replaced by hexmap, and dockhand has been replace by renovate/argocd
Anything installed with curl-to-bash needs to be documented before it’s forgotten.
