Destination rules are critical resources of Service Mesh (ASM) instances for traffic routing. Destination rules define policies that apply to traffic intended for a service after routing has occurred. Destination rules specify configurations for load balancing, connection pool size from the sidecar, and outlier detection settings to detect and remove unhealthy hosts from the load balancing pool. This topic describes how to create, modify, and delete a destination rule.
