Using Spanner Emulator for Benchbase

You can start the emulator using up.sh. This just simply launches the following command...docker run -p 9010:9010 -p 9020:9020 gcr.io/cloud-spanner-emulator/emulator. To be truly useful the emulator must be configured using gcloud. I used the following commands to get the emulator properly configured after starting.

1. Create a new config called emulator-config with the following properties:

gcloud config configurations create emulator-config
gcloud config set auth/disable_credentials true
gcloud config set api_endpoint_overrides/spanner http://localhost:9020/
gcloud config set project benchbase-project

2. Create a Spanner instance called benchbase-instance inside the emulator using the new config called emulator-config

gcloud spanner instances create benchbase-instance --config=emulator-config --description="Benchbase Emulator Instance" --nodes=1

5. Create a new Spanner database called benchbase in the new benchbase-instance.

gcloud spanner databases create benchbase --instance benchbase-instance

Once you are done you can clean up the resources you've created...

1. This will delete the Spanner instance.

gcloud spanner instances delete benchbase-instance

2. Activate your default configuation.

gcloud config configurations activate default

3. Delete your emulator-config.

gcloud config configurations delete emulator-config

4. Bring down the Emulator docker image.
