otel-collector

This module encapsulates producing a sidecar image for publishing otel collected metrics, and granting the service account as which the sidecar runs permission to write those metrics (so it's impossible to forget):

module "otel-collector" {
  source = "chainguard-dev/common/infra//modules/otel-collector"

  project_id      = var.project_id
  service_account = google_service_account.this.email
}

resource "google_cloud_run_v2_service" "this" {
  template {
    service_account = google_service_account.this.email
    containers {
      image = "..."

      // Specifying port is necessary when there are multiple containers.
      ports { container_port = 8080 }
    }
    // Install the sidecar!
    containers { image = module.otel-collector.image }
  }
}

This module is automatically invoked by the regional-go-service module.
