Google Config Sync

GitOps synchronization: Config Sync automates synchronization of configuration and policies across any number of clusters.
Automatic reconciliation: It continuously monitors the source of truth and reconciles cluster state to match it, preventing configuration drift.
Source types: Config Sync syncs configuration files from Git repositories, OCI images, and Helm charts.
Policy management: It can consistently apply Policy Controller constraints across registered and connected clusters.
Namespace management: It provisions and manages Kubernetes namespaces with namespace-scoped policies such as RBAC roles for multi-tenancy.
Cluster modes: Config Sync supports both Autopilot and Standard GKE clusters.
Fleet requirement: Clusters must be registered to a fleet before Config Sync can be enabled.
Identity security: Workload Identity Federation for GKE is the recommended way to securely connect to Google Cloud services and is required for fleet packages.
Architecture: Config Sync includes hosted components running in Google Cloud and open source components running on the GKE cluster.
OCI signature verification: For OCI repositories, Config Sync can integrate with a Kubernetes admission webhook signature verification server to help ensure only trusted OCI images are used.
Drift prevention limitation: The drift-prevention admission webhook can cause high memory usage and out-of-memory errors in clusters with many custom resources.
Node architecture limitation: Config Sync runs only on x86-based nodes and not on Arm nodes.
Support: Google Cloud offers support packages including 24/7 coverage, phone support, and access to a technical support manager.
Support scope: Google does not support issues with customer-owned YAML file configurations.
