How to fix unexpected argument ‘–frozen-lockfile’ found in pnpm 12

The unexpected argument '--frozen-lockfile' found error appears because npm install -g pnpm now installs pnpm 12, rewritten in Rust, and its CLI no longer takes a space-separated value. Replace --frozen-lockfile false with --no-frozen-lockfile, and pin pnpm in your Dockerfile and in packageManager so the next major does not surprise you.

Semaphore: Ansible UI When the Team Grows

Semaphore is the open-source Ansible web UI that solves the four scaling problems: audit trails, role-based permissions, execution history, and centralised secrets. It consumes ~500 MB versus AWX at ~4 GB. The pragmatic choice for mid-size teams that have outgrown running playbooks from a shared terminal.

Flux CD vs ArgoCD: Which to Choose for Your Platform

Flux CD and ArgoCD are the two CNCF-graduated GitOps tools for deploying to Kubernetes with Git as the source of truth. ArgoCD offers a centralised visual UI that manages several clusters from one instance, while Flux is a set of Kubernetes-native controllers with built-in image automation. Neither choice is wrong: it depends on your team and use case.

SLSA Level 3: Hardening the Software Supply Chain

SLSA v1.0, published in April 2023, defines four maturity levels for securing the software supply chain, from basic provenance to isolated builds. Level 3 requires every build to run in an ephemeral, stateless environment, eliminating attacks like build contamination and insider threat, and is achievable with GitHub Actions and OIDC signing via Sigstore.

Trivy and Grype: Container Image Scanning in CI

Trivy and Grype are the two leading open-source tools for container image scanning in CI/CD pipelines. Both detect CVEs in OS packages and language dependencies with less than 5% coverage difference. Trivy stands out for IaC scanning; Grype natively integrates the SBOM workflow with Syft.
