Wasm service

The WasmService configuration specifies a singleton or per-worker Wasm service for background or on-demand activities.

Example plugin configuration:

  1. bootstrap_extensions:
  2. - name: envoy.bootstrap.wasm
  3.   typed_config:
  4.     "@type": type.googleapis.com/envoy.extensions.wasm.v3.WasmService
  5.     singleton: true
  6.     config:
  7.       name: "my_plugin"
  8.       configuration:
  9.         "@type": type.googleapis.com/google.protobuf.StringValue
  10.         value: |
  11.           {
  12.             "my_config_value": "my_value"
  13.           }
  14.       vm_config:
  15.         runtime: "envoy.wasm.runtime.v8"
  16.         code:
  17.           local:
  18.             filename: "/etc/envoy_filter_http_wasm_example.wasm"

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