Google Cloud Pub/Sub Emulator

This repository contains configuration for a Docker image that contains the Google Cloud Pub/Sub emulator. It is simply a Dockerised version of https://cloud.google.com/pubsub/docs/emulator.

Usage

Command Line

This shell statement shows the basic usage, which will create a Pub/Sub emulator running on port 8085, with a project name of “testproject”, a default topic of “testtopic” and a subscription of “testsubscription”.

```shell script
docker run —rm —publish 8085:8085 jessejacksondocker/pubsub-emulator:latest

You can also configure the Pub/Sub project name, topic name, subscription name and exposure port:
```shell script
docker run --rm --env PUBSUB_PROJECT=myproject --env PUBSUB_TOPIC=mytopic --env PUBSUB_SUBSCRIPTION=mysubscription --env PUBSUB_PORT=10101 --publish 10101:10101 jessejacksondocker/pubsub-emulator:latest

Docker Compose

This is the equivalent configuration for docker-compose, with custom environment variables for the project name, topic name, subscription name and Pub/Sub port.
