CloudNativePG's ImageVolume Extensions: What Loading pgvector Without Rebuilding the Postgres Image Actually Costs a Self-Hosted PaaS
PostgreSQL 18's extension_control_path and Kubernetes' ImageVolume let CloudNativePG mount pgvector and other extensions as separate OCI images instead of rebuilding the Postgres image — here's the real version-gate checklist and the ongoing maintenance cost that comes with it.
What Cloud Native Buildpacks' Convention Buys a Git-Push PaaS Over a Hand-Rolled Build Script — and the One Escape Hatch It Still Needs
Cloud Native Buildpacks trades a hand-rolled detect-and-build script for community-maintained language coverage, reproducible image digests, and built-in SBOMs — but a git-push PaaS still needs a Dockerfile escape hatch for the repos convention can't detect.
CNCF Says Cloud Native Already Runs AI. Here's What Actually Transfers to a Git-Push PaaS
CNCF says the same cloud-native primitives already run web apps and AI workloads. Here's exactly what transfers to a git-push PaaS today — GitOps, containers, observability — and what still doesn't: GPU scheduling, disaggregated serving, and multi-agent orchestration.
Docker Cancels Hub Pull-Rate Charges Outright: What Walking Back a Pricing Threat (Not Just Postponing It) Signals About Registry Cost Risk on Owned Hardware
Docker didn't just delay its Hub pull-consumption pricing again — it cancelled the plan outright in April 2025. Here's what that reversal actually changed, what rate-limit risk survived it untouched, and what a pull-through cache costs to run on owned hardware versus metered cloud infrastructure.
HAMi Becomes a CNCF Incubating Project: What Fractional GPU Sharing Actually Buys a Fleet With a Handful of Cards
HAMi just reached CNCF Incubating status, and its own case studies show why it matters: DaoCloud cut GPU costs roughly in half after adopting it. Here's the actual per-tenant cost math for fractional GPU sharing versus buying a whole card per AI-agent sandbox.
Hetzner's 45-Hour ASH Load Balancer Outage: What a Managed LB Costs a Fleet That Doesn't Run Its Own
A Hetzner-managed Load Balancer in ASH went down for 45 hours on July 13, 2026, taking every healthy tenant behind it offline. Here's the actual blast-radius math, and what running kube-vip or MetalLB yourself instead would have cost and bought back.
Ingress-NGINX Is Already Retired: An Ingress2Gateway Migration Walkthrough for Self-Hosted Clusters
Ingress-NGINX's retirement isn't a future deadline — it happened in March 2026, and unpatched clusters have been exposed for months since. A concrete ingress2gateway walkthrough against a real annotation set shows exactly what converts automatically and what needs a hand pass.
Istio's Ambient Multicluster Reaches Beta: What Sidecarless Cross-Cluster Mesh Actually Costs a Hetzner-Spanning Cluster API Fleet
Istio 1.29 shipped ambient multicluster support at Beta. Here's the actual latency and control-plane cost of turning it on across a Cluster API fleet spread over Hetzner's separate locations — and the five gaps that keep it from being the default.
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.
