kustomize-controller

The kustomize-controller is a Kubernetes operator, specialized in running continuous delivery pipelines for infrastructure and workloads defined with Kubernetes manifests and assembled with Kustomize.

Features:

• watches for Kustomization objects
• fetches artifacts produced by source-controller from Source objects
• watches Source objects for revision changes
• generates the kustomization.yaml file if needed
• generates Kubernetes manifests with kustomize build
• decrypts Kubernetes secrets with Mozilla SOPS
• validates the build output with client-side or APIServer dry-run
• applies the generated manifests on the cluster
• prunes the Kubernetes objects removed from source
• checks the health of the deployed workloads
• runs Kustomizations in a specific order, taking into account the depends-on relationship
• notifies whenever a Kustomization status changes

Specifications:

• API
• Controller

Usage

The kustomize-controller is part of a composable GitOps toolkit and depends on source-controller to acquire the Kubernetes manifests from Git repositories and S3 compatible storage buckets. Install the toolkit controllers

Download the flux CLI:

curl -s https://toolkit.fluxcd.io/install.sh

Install the toolkit controllers in the flux-system namespace:

flux install
