pubsub-emulator-demo

Example Spring project showing how to use launch GCP emulator and test spring GCP pubsub in a test.

Key points:

• test-containers library is used to launch google-sdk docker container and start pubsub emulator inside it
• Tests are overridden to hit emulator via src/test/resources/test.properties by setting spring.cloud.gcp.pubsub-emulator-host: localhost:8085 (default emulator port)
• TestPubSubConfig is used to bring up pubsub emulator inside a docker container, create a topic and subscription in the emulator. This is using GCP SDK directly, not Spring pubsub, to create the resources.

Docker Installation required

Docker should be install and container environment must be LINUX.
