Exports limits and usage for metrics available through the GCP APIs (currently only supports Compute Engine).

1. Set up a service account in the project you wish to monitor. The account should be given the following permissions:

• compute.projects.get
• compute.regions.list

1. Authentication is performed using the standard Application Default Credentials

• To use a credentials.json key file export the environment variable GOOGLE_APPLICATION_CREDENTIALS=path-to-credentials.json

1. The exporter need to know which project to monitor quotas for

• Specify project using --gcp.project_id
• Export environment variable GOOGLE_PROJECT_ID
• Fetch from compute metadata http://metadata.google.internal/computeMetadata/v1/project/project-id

1. Copy the example file and add your project id to it
2. Change the volume to point to your credentials file if different
3. Run docker-compose up and you'll have a prometheus instance running at http://localhost:9090 and a gcp-quota-exporter instance running at http://localhost:9592.

docker build -t gcp-quota-exporter .
docker run -it --rm -v $(pwd)/credentials.json:/app/credentials.json -e GOOGLE_APPLICATION_CREDENTIALS=/app/credentials.json -e GOOGLE_PROJECT_ID=project_id gcp-quota-exporter

docker run -it --rm -v $(pwd)/credentials.json:/app/credentials.json -e GOOGLE_APPLICATION_CREDENTIALS=/app/credentials.json -e GOOGLE_PROJECT_ID=project_id mintel/gcp-quota-exporter
