A pre-built Docker container is available for Docker Hub:

docker run -p 8086:8086 ssivart/bigtable-emulator

Use any client app to connect to emulator by setting the BIGTABLE_EMULATOR_HOST environment variable to the host and port where the Bigtable emulator is running.

env BIGTABLE_EMULATOR_HOST=localhost:8086 ./myapp

or

           -e BIGTABLE_PROJECT=my-project \
