Using Cake for Kustomize

Kustomize lets you template and patch Kubernetes configurations without forking YAML files. Cake makes it easy to manage Kustomize workflows across environments with automation, validation, and Git-based deployments.

How it works

Customize Kubernetes workloads declaratively with Kustomize on Cake

Cake integrates Kustomize directly into GitOps workflows—so you can manage environment-specific patches, enforce policy, and deploy across clusters with full automation and version control.

Patch-based configuration management

Use Kustomize overlays to patch images, replicas, config maps, or secrets per environment—fully integrated into Cake’s GitOps deployment flows.

GitOps-native deployments

Run Kustomize overlays as part of Git-based workflows using Cake’s native Argo CD integration for reproducible, traceable deployments.

Environment-aware validation

Cake applies guardrails and checks to ensure Kustomize changes align with policy and environment-specific requirements.

Frequently asked questions about Cake and Kustomize

What is Kustomize?
Kustomize is a Kubernetes-native tool for customizing deployments by layering patches on top of base manifests, without modifying the base YAML.
How does Kustomize compare to Helm?
Kustomize is ideal for layering and patching Kubernetes configs using overlays. Helm is better for templating and packaging reusable charts. Cake supports both, depending on how you structure your workloads.
How does Cake integrate Kustomize?
Cake runs Kustomize overlays inside GitOps pipelines—validating changes, applying them across environments, and enforcing policy before promotion.
What kinds of changes can I manage with Kustomize?
You can patch images, replica counts, config maps, secrets, labels, and more—without touching the base YAML files.
Can I use Kustomize for multi-env workflows?
Yes. Cake supports managing staging, dev, and prod environments using Kustomize overlays and deployment pipelines.
