YAML Validator –A simple Docker-based YAML checker

Hi HN, I made a tiny tool called YAML Validator that checks your YAML files with one Docker command — no installs, no setup, no excuses. It does: - Syntax checks - yamllint linting - checkov security scanning - All in one lightweight, zero-config container --------------------------------------------------------- How to use: docker run -v "$(pwd):/data" pooyanazad/yaml-checker Optional alias (for .bashrc / .zshrc): alias ytest='docker run -v "$(pwd):/data" pooyanazad/yaml-checker' Then simply call: ytest sample.yaml YAML powers CI/CD, configs, infra ,and…

  • Holos – Configure Kubernetes with CUE data structures instead of YAML2024 · holos.run · ▲77

    Hi HN! I’m excited to share Holos, a Go command line tool we wrote to fill the configuration management gap in Kubernetes. Holos uses CUE to configure software distributed with Helm and Kustomize using a well defined, type safe language eliminating the need to template YAML. You probably know (or are) someone who has suffered with the complexity of plain text YAML templates and merging multiple values.yaml files together to configure software running in Kubernetes. We built Holos so we don’t have to template YAML but we can still integrate software distributed with Helm and Kustomize…

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
