Cosign keyless signing uses GitHub OIDC + Fulcio + Rekor to sign container images without managing private keys. Here's how it actually works and why you want it.

Spin, WasmEdge, and wasmCloud compared: what WASM containers can actually replace in 2026, where Docker still wins, and which tools are production-ready.

The CRI runtime under your Kubernetes cluster, cri-o vs containerd compared on footprint, distros, performance, and day-2 operability.

nerdctl is the containerd-native docker CLI replacement, when it's a drop-in, when it's not, and why you'd bother switching at all.

Containers aren't security boundaries, Sysbox, gVisor, and Kata fix that. Here's which isolation runtime fits your actual threat model.

Trivy, Grype, and Docker Scout go head-to-head on speed, CVE coverage, CI integration, and cost. Pick the right scanner for your home lab or pipeline.

systemd-nspawn ships on every modern Linux box and most sysadmins have never touched it. Here's when this no-daemon, no-Docker-socket container runtime is actually the right tool.

Distroless containers are tiny, secure, and loved by security teams, until you need to debug one at 2 AM. Here's when Google distroless actually pays off vs when it's just container hipster points.

Docker Desktop got expensive and RAM-hungry. Colima is the lean alternative. OrbStack is the one everyone's actually using now. Here's the honest breakdown for Mac developers.

A Software Bill of Materials tells you exactly what's in your software. Syft generates one, Grype scans it for CVEs. Together they're your supply chain paper trail.

Pulling unscanned images onto your server is a gamble. Trivy finds the CVEs. Cosign proves the image hasn't been swapped out. Here's how to add both to your workflow.

Falco watches every syscall your containers make and screams when something sketchy happens. Like someone exec'ing a shell inside your nginx container at 3am.
