SKILLS
A certification says what an exam asks. A skill says what a job asks: the environment you will be handed on the first day, and the faults you will be asked to find in it. These cartridges are built around a generic platform as it runs in production — the layers, the settings, the collector, the gateway — for the interview that asks how you would look into a blank dashboard, and for the engineer already inside one who wants to know it better.
🚢 OPERATOR CONVOY
a stack you run
Platform — no exam, only production, so you keep the convoy together.
The supporting cast of a hardened cluster — mesh, policy, identity and secrets, observability, backup, supply chain, delivery — the tools engineers live in between exams.
- Network and Mesh
- Policy and Admission
- Identity, Secrets and PKI
- Observability
- Runtime Security
- Supply Chain and Registry
- Stateful Services and Backup
- Delivery and Provisioning

🔭 SIGNAL SOUNDING
a stack you run
Observability — no exam, only a pager, so you take soundings before the alarm.
Observability inside a running platform — reading the environment, collection, the store and the query, alerting and routing, dashboards and SLOs, the platform's own health — the faults a tenant reports and where to look first.
- Reading the Environment
- Collection
- Storage and Query
- Alerting and Routing
- Dashboards and SLOs
- The Platform's Own Health

🐕 FETCH
a tool you use
K9s — no exam at all, so it drills composure. Routes, par, strokes.
Cluster triage at the speed of muscle memory: views, scopes, filters and panes — the keys you reach for while something is on fire.
