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.
