Chart Preview – Preview environments for Helm charts on every PR
I’m a software engineer who accidentally became my team’s Kubernetes person — and eventually the bottleneck for every Helm chart PR. I built Chart Preview so reviewers could see Helm chart changes running without waiting on me. A few years ago, my team needed to implement HA for an existing product, which meant deploying on Kubernetes and OpenShift. I spent months learning Kubernetes, Helm, and the surrounding ecosystem. After that, Kubernetes largely became “my thing” on the team. We later published public Helm charts for the product, and customers started submitting PRs. Those PRs would…

In plain words
Chart Preview is a development tool that automatically generates preview environments for Helm chart changes on pull requests. It allows reviewers to see how Kubernetes deployments will run with proposed changes without manual cluster setup or waiting for specialized team members. Designed for teams managing Helm charts and Kubernetes deployments, it reduces bottlenecks in the PR review process by enabling anyone to verify chart modifications in a working environment directly from the pull request.

From the sources
Chart Preview creates ephemeral preview environments for Helm charts on every pull request — no cluster to manage and no preview infrastructure to maintain. Connect your GitHub or GitLab repository and each PR is automatically deployed to an isolated Kubernetes environment with a live preview URL. Previews update on push and clean up automatically when the PR is closed or merged. ✓ Helm charts from Git, OCI, or TGZ ✓ PR/MR status checks with deployment logs
Deploy and test your Helm charts instantly with every pull request. Kubernetes-native preview environments with GitHub integration.
Early Access: Chart Preview is onboarding users manually. Install the GitHub App and we'll enable your previews within 24 hours. Deploy your Helm charts on every pull request. Any Git provider. We handle the cluster. Stop waiting for staging. Let reviewers, QA, and stakeholders test changes on a live URL before merge. Setting up preview infrastructure means provisioning clusters, configuring ingress, managing DNS, handling cleanup... or you could just use Chart Preview. One-click install on your repository. Get your API token automatically. Copy the simple workflow from the onboarding PR to your repo. We handle the Kubernetes infrastructure. You just deploy your charts. Every PR gets a…from chart-preview.com

A universal Helm Chart for deploying applications into K8s/OpenShift2024 · github.com · ▲42Hey HN! We wanted to share with you nxs-universal-chart - our open-sourced universal Helm chart. You can use it to deploy any of your applications into Kubernetes/OpenShift and other orchestrators compatible with native Kubernetes API. Our team regularly faced the need to create almost identical charts, so when we had 14 identical microservices in one project, we came up with a chart format that essentially became a prototype of nxs-universal-chart. It turned out to be more relevant than we even thought! When we needed to prepare CI/CD for 60 almost identical projects for a…

Talanoa▲346Hi 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…
