Running your own PaaS and infrastructure on machines you own
Crossplane vs Cluster API: Two CNCF Answers to "Should Infrastructure Be an API?" — and Where a Self-Hosted PaaS Draws the Line
Crossplane models everything from databases to GPU inference fleets as one declarative API; Cluster API keeps a written list of what it refuses to manage beyond cluster lifecycle. A side-by-side of what each CNCF project actually optimizes for, why they compose as layers rather than compete, and why a self-hosted PaaS builds on Cluster API while skipping multi-cloud abstraction.
Heroku Is in Sustaining-Engineering Mode. Dokku Is the Obvious Exit — Here's What It Actually Gets You (and What It Doesn't)
Heroku's February 2026 shift to sustaining engineering has teams planning exits. A grounded look at migrating to Dokku: the Heroku-to-Dokku concept map, the honest limits of a single-server PaaS, the ten-command migration, and where the one-box ceiling ends.
Gitea's Docker Image Trusted Every Proxy on Earth: A Five-Question Audit for the Defaults Baked Into Your Images
Gitea's container image shipped REVERSE_PROXY_TRUSTED_PROXIES = * while its own docs said loopback-only — CVSS 9.8, armed by the very SSO flag a platform is supposed to set. Five runnable questions, plus a CI check, for auditing the defaults hiding in every image and chart your platform ships.
Headlamp's Knative Plugin Surfaces Traffic Splitting and Scale-to-Zero in One View: What a Serverless Runtime Actually Needs From a Cluster API Fleet's Ingress Layer
The June 2026 Headlamp plugin makes Knative traffic splits and scale-to-zero state visible in one view. Here is what those primitives buy a git-push PaaS, the Gateway API stack a Cluster API fleet must run underneath, the cold-start bill tenants pay, and why scale-to-zero should be opt-in for production routes.
Healthchecks.io Walks Off Managed S3: The Egress-and-Request-Fee Math of Self-Hosting Object Storage
Healthchecks.io moved 14M objects off managed object storage onto one dedicated server — and paid more. The real math: ~$390/mo in S3 PUT fees vs $2.74 storage, the egress trap priced out, what self-hosting adds to the pager, and when running state on your own metal wins.
The 4GB RAM Price Gap: What Hetzner at $4 vs Heroku at $260 Actually Buys You
A 4GB-RAM machine costs $4 on Hetzner and $250+ on Heroku. Re-verified 2026 prices, an itemized look at what the 14x–125x premium buys, and a break-even table that prices in your own ops hours.
Hetzner Raised Prices Three Times in Six Months: The "Just Use a Cheap Hetzner Box" Math, Recomputed
Hetzner repriced three times in six months, pushing dedicated-vCPU and bare-metal lines up 2.3-3.7x on June 15, 2026. A line-by-line recompute of the self-hosting-vs-managed-PaaS math on the new price list — including the tier where an 11x advantage compressed to 4x, and why self-healing fleets forfeit grandfathered pricing.
Metering Your Tenants: Build a Kubernetes Metrics Exporter for Railway-Style Usage Showback
Build a small Go exporter that turns cAdvisor's CPU, working-set memory, and network counters into per-app usage statements priced at Railway's public meters — plus the five cAdvisor pitfalls that silently corrupt naive per-container accounting.
Kubernetes v1.37's Deprecation Sweep: The Migration Inventory a Cluster API Fleet Needs Before August 26
Kubernetes v1.37 lands August 26, 2026, and the July 31 sneak peek already names every deprecation and breaking change. Here is the full migration inventory for a Cluster API fleet — ipvs kube-proxy, static-pod Secret refs, cgroup v1, SELinuxMount GA — with the audit command and deadline for each.
