A number of environment variables can be used to configure the behavior of the library. There are also functions to configure this behavior in code. The environment variables are convenient when troubleshooting problems.
Endpoint OverridesGOOGLE_CLOUD_CPP_IDENTITY_AWARE_PROXY_ADMIN_SERVICE_ENDPOINT=... overrides the EndpointOption (which defaults to "iap.googleapis.com") used by MakeIdentityAwareProxyAdminServiceConnection().GOOGLE_CLOUD_CPP_IDENTITY_AWARE_PROXY_O_AUTH_SERVICE_ENDPOINT=... overrides the EndpointOption (which defaults to "iap.googleapis.com") used by MakeIdentityAwareProxyOAuthServiceConnection().GOOGLE_CLOUD_CPP_ENABLE_TRACING=rpc: turns on tracing for most gRPC calls. The library injects an additional Stub decorator that prints each gRPC request and response. Unless you have configured your own logging backend, you should also set GOOGLE_CLOUD_CPP_ENABLE_CLOG to produce any output on the program's console.
google::cloud::TracingComponentsOptionGOOGLE_CLOUD_CPP_TRACING_OPTIONS=...: modifies the behavior of gRPC tracing, including whether messages will be output on multiple lines, or whether string/bytes fields will be truncated.
google::cloud::GrpcTracingOptionsOptionGOOGLE_CLOUD_CPP_ENABLE_CLOG=yes: turns on logging in the library, basically the library always "logs" but the logging infrastructure has no backend to actually print anything until the application sets a backend or they set this environment variable.
GOOGLE_CLOUD_PROJECT=...: is used in examples and integration tests to configure the GCP project. This has no effect in the library.
