Active operations repo
AppserviceThe private GitOps repository that holds desired state, recovery rules, and operational evidence for the cluster. is the operations repository for a Talos-based Kubernetes cluster. Reconciliation, encrypted secrets, recovery gates, upgrades, and incident evidence live with the desired state instead of in operator memory.
Guiding claim · Current · Homelab operations
A live migration needs more than a target diagram. Before changing the first node, name the temporary configurations, the checks between them, who controls each handoff, and the point after which rollback stops being cheap.
Guiding claim · Current · GitOps operations
Two upgrade failures came from persistent node-local state outside Git: malformed UEFI NVRAM and an iSCSI record that poisoned shared parsing. The fix was bounded exceptions, preflight checks, controlled migration and verification.
Guiding claim · Current · Release engineering
A release candidate passed every gate and failed on contact with production six minutes later. The gates proved compatibility with the target database state; nothing had proved the transition from the state actually running.
Guiding claim · Current · Cluster operations
Migrating a Talos cluster from a legacy subnet to its own VLAN while it kept serving. The design was mostly an ordering problem, plus one bootstrap loop: the network controller lives inside the network it manages.
Archival claim · Archived · GitOps operations
A live rollback fixed a crashlooping workload, but the more interesting part was needing to suspend reconciliation long enough for the fix to become the desired state instead of a temporary lie.
