This directory contains the following Google Cloud Functions.

Programatically triggers a Cloud Build on master. This function is called by the Cloud Scheduler around 4am "America/New York" time every day (configurable via the Cloud Scheduler UI). You can also trigger the function manually via the Cloud UI.

Command to re-deploy:

gcloud functions deploy nightly_tfjs \
  --runtime nodejs8 \
  --trigger-topic nightly_tfjs

If a build was triggered by nightly, there is a substitution variable _NIGHTLY=true. You can forward the substitution as the NIGHTLY environment variable so the scripts can use it, by specifying env: ['NIGHTLY=$_NIGHTLY'] in cloudbuild.yml. E.g. integration_tests/benchmarks/benchmark_cloud.sh uses the NIGHTLY bit to always run on nightly.
