Kustomize features and specs

  • Declarative Syntax
    Kustomize provides a declarative approach to managing Kubernetes configurations, allowing users to specify desired states in YAML files rather than using scripts or imperative commands.
  • No Templating Required
    Unlike Helm, Kustomize does not use templates, reducing complexity and potential errors in rendering templates. Users can simply modify YAML files directly.
  • Layered Customization
    It allows users to apply multiple overlays or transformations to base configurations, enabling a modular and reusable approach to manage environments like dev, staging, and production.
  • Integration with kubectl
    Kustomize is integrated with kubectl since version 1.14, making it easy to use and deploy directly from the command line without needing additional tools.

Possible disadvantages of Kustomize

  • Complexity for Large Projects
    While Kustomize is great for simple transformations, managing large projects with many overlays can become complex, as dependencies and transformations have to be explicitly defined and managed.
  • Limited Features Compared to Helm
    Kustomize offers fewer features compared to Helm, such as lifecycle management and rich templating, which might be needed for more sophisticated deployment requirements.
  • Learning Curve
    Users new to Kubernetes configuration management might find Kustomize's model and functions hard to grasp initially, as it requires understanding of its specific YAML structure and practices.
  • Lack of Native Dependency Management
    Kustomize does not support native dependency management of resources, which can complicate handling interdependent resources compared to other tools like Helm.

Questions & Answers

As answered by people managing Kunobi and Kustomize.

Why should a person choose your product over its competitors?

Kunobi's answer

If you're tired of Lens eating 2GB of RAM or k9s not being visual enough, Kunobi sits in the middle. Native desktop performance with a proper GUI. It handles multi-cluster management, has a real terminal system with split panes, and lets you spin up local KIND clusters for testing without leaving the app. GitOps teams get a flow graph that shows Flux dependencies visually instead of making you dig through YAML.

We are expanding into areas beyond k8s -> idrac, cloudflare, github, etc. to have a complete view of your platform.

What's the story behind your product?

Kunobi's answer

Kunobi came from managing Kubernetes at scale at Zondax. Terminal tools like k9s are fast but lack visibility acrossclusters and GitOps flows. GUI tools like Lens offer that visibility but consume gigabytes of memory.

We built Kunobi to give platform teams both: native performance with the multi-cluster and GitOps visualization that enterprise operations demand.

Which are the primary technologies used for building your product?

Kunobi's answer

Rust (fast!), React (beautiful), WebGL (faster!), plus an expert human-team to avoid AI slop

  • Release on Demand
    When a change earns its way onto main, the train builds the container image one time and tags it by the commit SHA. That image is the artifact. It runs in dev immediately. And here's the part that makes promotion boring: shipping to prod doesn't rebuild anything. It re-points a config overlay (a Kustomize overlay, in practice, committed to the same repo) at the same SHA that's already running in dev. Same bytes,... - Source: dev.to / 3 months ago

    Once I covered these basic use cases, I started to review the code base of the InnerSource pipeline project. At this point I learned about kustomize which is a Kubernetes native way for updating existing configurations. This tool was used in the project to customize default configurations of various manifests, so that new, slightly different ones could be created without code duplication.
