espv2protoyaml

You may want this to build api_config.yaml programmatically. Enumerating RPC calls is your own bag.

Usage

./espv2protoyaml \
    -backend helloworld.Greeter \
    -endpoint-name hellogrpc.endpoints.YOUR_PROJECT_ID.cloud.goog \
    -endpoint-title helloworld.Greeter \
    -usage-rule hellogrpc.endpoints.YOUR_PROJECT_ID.cloud.goog.Greeter,true \ # selector,unregisteredCallFlag
    -backend-rule '*',grpcs://<CLOUD_RUN_NAME>-<HASH>-uc.a.run.app # selector,address

Flags

  -backend value
    gRPC service name. Can be repeated
  -backend-rule value
    Comma separated RPC address and selector. Can be repeated.
  -config-version int
    config version (default 3)
  -endpoint-name string
    GCP endpoint name
  -endpoint-title string
    GCP endpoint title
  -h string
    Prints this message
  -o string
    API Config path (default: api_config.yaml). '-' works. (default "api_config.yaml")
