Chapter 7: Automating Helm Processes Using CI/CD and GitOps

In this book, we have so far discussed two high-level processes. First, we explored using Helm as an end user, leveraging Helm as a package manager to deploy applications of varying complexities to Kubernetes. Second, we explored developing and testing Helm charts as a chart developer, which involved encapsulating Kubernetes complexities in Helm charts and performing tests on charts to ensure that the required features were delivered to end users successfully.

Both of these processes involve invoking various different Helm CLI commands. These Helm CLI commands, while effective in carrying out their respective tasks, require manual invocation from the command line. Manual invocation can serve as a pain point when managing multiple different charts or applications and can make it difficult for larger enterprises to scale. As a result, we should explore alternative options that provide additional automation on top of what...
