Environment details
- OS type and version: MacOS 11.2.2 (20D80) & Docker 3.2.1
- Python version: Python 3.9.2
- pip version: pip 21.0.1
google-cloud-pubsub version: 2.2.0
Steps to reproduce
Use the following docker-compose.yml file:
version: "3.7"services:
pubsub:
image: google/cloud-sdk:331.0.0command: gcloud beta emulators pubsub start --host-port=0.0.0.0:8085ports:
- "8085:8085"restart: unless-stoppedpublisher:
image: python:3.9.2command: sh -c "pip install google-cloud-pubsub~=2.2.0 && python /app/publish.py"volumes:
- .:/appenvironment:
- PUBSUB_EMULATOR_HOST=pubsub:8085
- PUBSUB_PROJECT_ID=test-project
and the following content as publish.py in the same directory:
fromgoogle.cloudimportpubsub_v1project_id="test-project"topic_id="test-topic"publisher=pubsub_v1.PublisherClient()
topic_path=publisher.topic_path(project_id, topic_id)
publisher.publish(topic_path, b'My first message!')
When I run the file above, the execution fails with the library failing to run against the local emulator with the error:
google.auth.exceptions.DefaultCredentialsError: Could not automatically determine credentials. Please set GOOGLE_APPLICATION_CREDENTIALS or explicitly create credentials and re-run the application. For more information, please see https://cloud.google.com/docs/authentication/getting-started
As far as I understand, there should be no credentials involved since the script is running against the emulator, and I'd just expect the request to work as it is.
If I use the 2.1.0 version, the script works just fine. The reason I am running 2.2.0 is because of #325, and since there is no solution to that with 2.4.0 as of today, I needed to downgrade to this version. I am unable to test this due to being unable to run 2.4.0 against the emulator, therefore I wanted to report this in case this is a regression introduced with 2.2.0 that might be there for other versions as well.
