Wasm service

The :ref:WasmService <envoy_v3_api_msg_extensions.wasm.v3.WasmService> configuration specifies a singleton or per-worker Wasm service for background or on-demand activities.

Example plugin configuration:

.. code-block:: yaml

bootstrap_extensions:

• name: envoy.bootstrap.wasm typed_config: "@type": type.googleapis.com/envoy.extensions.wasm.v3.WasmService singleton: true config: name: "my_plugin" configuration: "@type": type.googleapis.com/google.protobuf.StringValue value: | { "my_config_value": "my_value" } vm_config: code: local: filename: "/etc/envoy_filter_http_wasm_example.wasm"

The preceding snippet configures a plugin singleton service from a Wasm binary on local disk.
