Google Cloud Spanner Emulator

This repository wraps the official Google Cloud Spanner Emulator with a convenience function to create an spanner instance on startup.

Usage

Set the SPANNER_DATABASE_ID, SPANNER_INSTANCE_ID and SPANNER_PROJECT_ID environment variables when running the image. You can omit the database id if you just need an instance.

docker run --env SPANNER_DATABASE_ID=db \
  --env SPANNER_INSTANCE_ID=inst \
  --env SPANNER_PROJECT_ID=proj \
  -p 9010:9010 -p 9020:9020 \
  roryq/spanner-emulator:latest
