Dynamic modules

The dynamic modules health checker is a custom health checker (with envoy.health_checkers.dynamic_modules as name) that delegates the actual health check to a dynamic module. Envoy drives the standard per-host interval, timeout and healthy/ unhealthy thresholds. On each interval the module performs the check (optionally on its own thread) and reports the host’s health status back to Envoy, which applies it on the main thread.

An example setting for custom_health_check as a dynamic modules health checker is shown below:

custom_health_check:
  name: envoy.health_checkers.dynamic_modules
  typed_config:
    "@type": type.googleapis.com/envoy.extensions.health_checkers.dynamic_modules.v3.DynamicModuleHealthCheck
    dynamic_module_config:
      name: my_health_checker_module
    health_checker_name: my_health_checker
    health_checker_config:
      "@type": type.googleapis.com/google.protobuf.StringValue
      value: example-config
