Configuration of the HTTP filter for dynamic modules. This filter allows loading shared object files that can be loaded via dlopen by the HTTP filter. A module can be loaded by multiple HTTP filters, hence the program can be structured in a way that the module is loaded only once and shared across multiple filters providing multiple functionalities.

• optional dynamic_modules.v3.DynamicModuleConfig dynamic_module_config = 1

  Specifies the shared-object level configuration.

• string filter_name = 2

  The name for this filter configuration. This can be used to distinguish between different filter implementations inside a dynamic module. For example, a module can have completely different filter implementations. When Envoy receives this configuration, it passes the filter_name to the dynamic module's HTTP filter config init function together with the filter_config. That way a module can decide which in-module filter implementation to use based on the name at load time.

• optional google.protobuf.Any filter_config = 3

  The configuration for the filter chosen by filter_name. This is passed to the module's HTTP filter initialization function. Together with the filter_name, the module can decide which in-module filter implementation to use and fine-tune the behavior of the filter. For example, if a module has two filter implementations, one for logging and one for header manipulation, filter_name is used to choose either logging or header manipulation. The filter_config can be used to configure the logging level or the header manipulation behavior. ``google.protobuf.Struct`` is serialized as JSON before passing it to the plugin. ``google.protobuf.BytesValue`` and ``google.protobuf.StringValue`` are passed directly without the wrapper. .. code-block:: yaml # Passing in a string filter_config: "@type": "type.googleapis.com/google.protobuf.StringValue" value: hello # Passing in raw bytes filter_config: "@type": "type.googleapis.com/google.protobuf.BytesValue" value: aGVsbG8= # echo -n "hello" | base64
