01 / Why it exists

Operating the control plane, nodes, upgrades, and failures builds fluency that managed abstractions intentionally hide.

02 / Architecture

k3s and containerd run across nine Linux nodes. Cilium provides networking, Argo CD reconciles desired state, and workload storage is selected from Longhorn, NFS, and local volumes.

03 / Lessons

What operation taught me.

01A healthy lab includes failure and recovery.
02The control plane is rarely the hardest part; state and networking carry the consequences.

Screenshots

Operational captures will be added when they can be safely published.
