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:

• Reconciles the cluster state from multiple sources (provided by source-controller)
• Generates manifests with Kustomize (from plain Kubernetes YAMLs or Kustomize overlays)
• Decrypts Kubernetes secrets with Mozilla SOPS and KMS
• Validates manifests against Kubernetes API
• Impersonates service accounts (multi-tenancy RBAC)
• Health assessment of the deployed workloads
• Runs pipelines in a specific order (depends-on relationship)
• Prunes objects removed from source (garbage collection)
• Reports cluster state changes (alerting provided by notification-controller)
