DESCRIPTION
(BETA) This command starts a local Cloud Spanner emulator.
EXAMPLES
To start a local Cloud Spanner emulator, run:
gcloudbetaemulatorsspannerstart
FLAGS
--enable-fault-injection=ENABLE_FAULT_INJECTION
If true, the emulator will randomly inject faults into transactions. Thisfacilitates application abort-retry testing.
--host-port=HOST_PORT
The host:port to which the emulator should be bound. The default value islocalhost:9010. Note that this port serves gRPC requests. To override thedefault port serving REST requests, use --rest-port. If using Docker to run theemulator, the host must be specified as an ipaddress.
--rest-port=REST_PORT
The port at which REST requests are served. gcloud uses REST to communicate withthe emulator. The default value is 9020.
--use-docker=USE_DOCKER
Use the Cloud Spanner emulator docker image even if the platform has a nativebinary available in the gcloud CLI. Currently we only provide a native binaryfor Linux. For other systems, you must install Docker for your platform beforestarting the emulator.
