Over-Engineered Kubernetes Is a Trap
- Helm charts introduce unnecessary complexity by hiding the deployment process with layers of templating and nested values.yaml files, making it harder to manage and troubleshoot.
- Combining YAML with Go templating as in Helm leads to complexity due to fragile constructs, making configurations difficult to read and maintain.
- Helm's dependency management adds complexity with nested charts and brittle version pinning, complicating customization and overriding values.
- Kustomize provides a declarative approach to Kubernetes configuration but blurs the line between declarative and imperative, requiring deep Kubernetes object understanding.
- Kustomize's use of patching mechanisms and dynamic behavior can lead to verbose, hard-to-maintain configurations and a complex layering of data-as-code.
- A Makefile approach to Kubernetes deployment using tools like sed, awk, and jq offers transparency, control, and ease of debugging compared to more complex tools like Helm.
- Using Makefiles for Kubernetes deployments enables customizable workflows and transparency, allowing for simpler string manipulation and greater control over the deployment logic.
- Constraints in Makefiles help ensure consistency and prevent errors by validating inputs, restricting configurations, and enforcing best practices during the build process.
- Generating labels dynamically based on parameters like target environment using Makefiles simplifies Kubernetes deployments and reduces repetition, enhancing consistency.
- The article emphasizes the simplicity and efficiency of Unix tools when handling Kubernetes deployments, advocating for minimal tool usage to maintain control and reduce complexity.
