Kompose Only Gets You 70-80% of the Way From docker-compose.yml to Kubernetes: Here's the Exact List of What's Missing

A field-by-field inventory of what Kompose v1.38 converts automatically, what it only converts if you add non-standard labels, and what a git-push PaaS's own Compose importer would need to fill in instead.

Kubernetes 1.36's PSI Metrics Graduate to GA: What Pressure Stall Information Catches About Resource Starvation That CPU% Utilization Misses

Kubernetes 1.36 locks PSI metrics to GA, catching resource stalls a CPU% dashboard can't see. Here's the worked example, the two ways the signal can lie, and the pre-flight checklist a bare-metal fleet needs before trusting it.

What Self-Hosting OpenMeter's Kafka+ClickHouse Stack Actually Costs a Git-Push PaaS

OpenMeter's self-hosted stack adds two new stateful services — Kafka and ClickHouse — to bill per millisecond. Here's what that actually costs in Hetzner hardware and ops burden against billing tenants on signals a PaaS already tracks for free.

CAPMOX Is Maturing Fast: What a Real Cluster API Provider for Proxmox Means Beyond Hetzner-Only Node Pools

IONOS's CAPMOX shipped six releases in fifteen months of active development — here's what the changelog actually shows, how it provisions a node, who else is building the same thing, and what a second CAPI provider really costs a Hetzner-only fleet.

CNCF's 19.9 Million Developers, +28% in Six Months: The Math That Says It's Not New Growth

CNCF says the cloud native developer population jumped 28% in six months to 19.9 million, with 7.3 million now AI developers. The arithmetic says that's not a wave of new developers — it's existing developers crossing a line, and it changes how fast a platform's agent golden path has to ship.

Devin Outposts: Cognition Shipped a Kubernetes Operator Instead of a Bigger Cloud

Cognition's Devin Outposts keeps the reasoning in the cloud but moves command execution onto your own machines — and shipped a Kubernetes operator to run it. Here's exactly what devin-outpost-k8s deploys and what a Cluster-API fleet needs to add to host it natively.

eBPF Made Continuous Profiling Nearly Free — But Someone Still Has to Store It: Parca vs. Pyroscope on a Self-Hosted Fleet

Parca and Pyroscope both run eBPF-based continuous profiling under 1% CPU overhead. Here's what standing either one up as a Cluster API service actually costs in storage and operational surface, worked against Datadog and Grafana Cloud's own profiling bills for the same fleet.

Hetzner's ARM (CAX) Instances Won't Save You Money Until Your Build Layer Can Target Them

Hetzner's ARM (CAX) Instances Won't Save You Money Until Your Build Layer Can Target Them

Hetzner's Ampere ARM (CAX) instances are pitched as cheaper per core than x86 CX. Current 2026 pricing says otherwise — and the real gate on ARM economics is whether your buildpacks pipeline can produce an arm64 image at all.

One Rack Switch Died in Nuremberg. Here's What a Hetzner Cloud Leaf Fault Actually Costs a Cluster API Fleet

On July 24, 2026, a switch fault in one Nuremberg rack took down Load Balancer, Networks, Cloud Server, and Object Storage together. What that actually costs a running CAPH cluster, why it's not a one-off, and the concrete mitigation CAPH exposes today.
