Supercharge Helm chart development with DaggerUse Dagger to achieve isolation and reproducibility with Helm
Blog post from OpenMeter
Infrastructure complexity necessitates robust isolation and reproducibility in software development to avoid common issues like "works on my machine" or "push-and-pray" scenarios. This text discusses how Dagger can be employed to achieve these objectives specifically with Helm and Kubernetes, allowing developers to run linters, tests, and push to a registry on their local machine identically to how it would function in a Continuous Integration (CI) environment. The process involves setting up Dagger and Docker, creating a new Helm chart, and using Nginx as the test application, with additional steps for customizing and testing the Helm chart on a local Kubernetes cluster. The workflow includes building and pushing the application image to a registry, setting up a lightweight Kubernetes cluster with k3s, and ensuring the chart installs correctly before running tests. Finally, the text highlights the ease of releasing Helm charts from a local machine using the Helm module, reinforcing Dagger as an effective tool throughout the development lifecycle, from creating to releasing a Helm chart.
