Kustomize Deployment FAQs
This article addresses some frequently asked questions about Kustomize deployments in Harness.
What is Kustomize, and how does it relate to Harness Next-Gen?
Kustomize is a Kubernetes-native configuration management tool that simplifies the customization of Kubernetes manifests. In Harness Next-Gen, Kustomize is used to manage and customize Kubernetes manifests for deployments.
What are Kustomize overlays, and why are they useful?
Kustomize overlays are a way to customize and extend Kubernetes manifests without modifying the original base manifests. Overlays allow you to apply environment-specific configurations, such as namespace, labels, and resource limits, to the base manifests, making it easier to manage different environments (e.g., dev, test, prod) within a single repository.
Can I use variables and secrets with Kustomize overlays in Harness?
Yes, you can use Harness variables and secrets in your Kustomize overlays to parameterize configurations and securely manage sensitive data.
What is the deployment process for Kustomize-based applications in Harness Next-Gen?
When you deploy a Kustomize-based application in Harness, Harness will automatically apply the specified overlay based on the target environment, ensuring that the Kustomized Kubernetes manifests are deployed correctly.
Can I preview and validate Kustomize manifests in Harness before deployment?
Yes, Harness provides a preview and validation feature for Kustomize manifests, allowing you to review and validate the customized manifests for correctness before initiating a deployment.
What are the benefits of using Kustomize manifest with Harness Next-Gen for Kubernetes deployments?
Using Kustomize with Harness simplifies the management of Kubernetes manifests by providing a declarative and version-controlled approach to customizations. It ensures consistency across environments and simplifies the deployment process.
What Kustomize binary versions Harness Support?
Harness includes Kustomize binary versions 3.5.4 and 4.0.0. By default, Harness uses 3.5.4. To use 4.0.0, you must enable the feature flag NEW_KUSTOMIZE_BINARY in your account
What are the constraints regarding Kustomize build commands within Harness, specifically in terms of supported commands and their functionality?
Harness supports the Kustomize build command only. The Kustomize build command builds a kustomization target from a directory or URL.

Can I design a pipeline to deploy Helm charts hosted in a remote private Helm registry and using Kustomize to patch the Helm charts?
Native Helm doesn't support Kustomize; however, you could use service hooks for this.
