Istio Mesh Config API
The Istio Mesh Config API (istio.mesh.v1alpha1) provides global configuration for the Istio service mesh control plane and data plane proxy behavior. It includes MeshConfig for mesh-wide settings such as access logging, tracing providers, and default proxy configuration, as well as ProxyConfig for per-workload proxy tuning and network topology settings. These settings are typically applied via the Istio ConfigMap or as annotations on workloads.
