Polaris is the statistics collection server for the Santa client. It receives requests over ConnectRPC from the Santa client and publishes the data into BigQuery.
See https://northpole.dev/deployment/stats for more details
Terraform is used to manage the configuration of the artifact registry, Cloud Run service, and BigQuery table. The terraform state is stored in a shared GCS bucket.
Deployments of new versions are automated through GitHub with the container image being created through GitHub actions, with attestation. This also triggers an update to the Cloud Run deployment.
