A docker container that runs the pubsub emulator and the datastore emulator.

Pub / Sub

Running

docker run -t -p 8538:8538 niallmccullagh/docker-google-cloud-emulators /bin/bash -c "gcloud config set project emulator && gcloud beta emulators pubsub start --data-dir /mnt/data/pubsub --host-port 0.0.0.0:8538"

Running with the compose

Using the compose file in the repository the pubsub emulator can be started by running

docker-compose up pubsub
