_{Companion packages: Cloud Scheduler, Cloud Tasks}

Introduction

This package lets you use Google Cloud Logging as the log driver for Laravel.

The package will automatically detect the environment it's running in (supports Cloud Run, App Engine, and GKE), and attach the correct labels to the log entry so the logs appear in the application service.

This package requires Laravel 12 or 13.

Installation

Install the package with Composer:

composer require marick/laravel-google-cloud-logging

Add a new logging channel in config/logging.php:

'google_cloud' => [
    'driver' => 'google_cloud',
    'location' => env('GOOGLE_CLOUD_LOGGING_LOCATION'),
],

Use the new channel:

LOG_CHANNEL=google_cloud

Important

A location is mandatory to make log entries appear in Cloud Run or App Engine.

How to

Use log context

use Illuminate\Support\Facades\Log;

Log::debug('user logged in', [
    'user' => 5,
]);

Context is nested under logContext in the JSON payload, supports any structure:

{
  "jsonPayload": {
    "message": "user logged in",
    "logContext": {
      "user": 5
    }
  }
}

Use Context

use Illuminate\Support\Facades\Context;
use Illuminate\Support\Facades\Log;

Context::add('user', 5);

Log::alert('user logged in');

Laravel Context values are nested under laravelContext in the JSON payload:

{
  "jsonPayload": {
    "message": "user logged in",
    "laravelContext": {
      "user": 5
    }
  }
}

Add labels

GCP labels are flat string key-value pairs, useful for filtering across log entries. There are three ways to add them:

Via config — applied to every log entry in the channel:

'google_cloud' => [
    'driver' => 'google_cloud',
    'labels' => ['environment' => 'production'],
],

Per log entry — pass a labels key in the log context:

Log::debug('user logged in', [
    'labels' => ['request_id' => $requestId],
]);

Per request — set once (e.g. in middleware), applied to all log entries for the request:

use Marick\LaravelGoogleCloudLogging\CloudLogging;

CloudLogging::withLabels(['tenant_id' => $tenantId]);

// Or lazily via a closure, resolved at log time:
CloudLogging::withLabels(fn () => ['user_id' => auth()->id()]);

Configure the log name

By default, log entries are written to the laravel log. You can change this per channel:

'google_cloud' => [
    'driver' => 'google_cloud',
    'location' => env('GOOGLE_CLOUD_LOGGING_LOCATION'),
    'log_name' => env('GOOGLE_CLOUD_LOG_NAME', 'laravel'),
],

Automatic enrichment

Every log entry is automatically enriched with the following:

HTTP request

{
  "httpRequest": {
    "requestMethod": "GET",
    "requestUrl": "https://example.com/users",
    "userAgent": "Mozilla/5.0 ...",
    "remoteIp": "1.2.3.4",
    "referer": "https://example.com",
    "protocol": "HTTPS"
  }
}

Source location

{
  "sourceLocation": {
    "file": "/var/www/html/app/Http/Controllers/UserController.php",
    "line": "42",
    "function": "App\\Http\\Controllers\\UserController::store"
  }
}

Trace correlation

When the X-Cloud-Trace-Context header is present (injected automatically on Cloud Run and behind GCP load balancers), trace information is attached to link log entries to Cloud Trace. Requires GOOGLE_CLOUD_PROJECT (or GCLOUD_PROJECT) to be set.

{
  "trace": "projects/my-project/traces/105445aa7843bc8bf206b12000100000",
  "spanId": "1",
  "traceSampled": true
}

Resource detection

The package detects the runtime environment and sets the correct GCP resource type so logs surface in the right place.

Cloud Run — detected via K_SERVICE and K_REVISION:

{
  "resource": {
    "type": "cloud_run_revision",
    "labels": { "service_name": "my-service", "revision_name": "my-service-00001-abc", "location": "europe-west1" }
  }
}

App Engine — detected via GAE_SERVICE and GAE_VERSION:

{
  "resource": {
    "type": "gae_app",
    "labels": { "module_id": "my-service", "version_id": "v1" }
  }
}

GKE — detected via KUBERNETES_SERVICE_HOST (automatically present in all pods). Set the following env vars via the Downward API to populate the resource labels:

Env var	Resource label
KUBERNETES_CLUSTER_NAME	cluster_name
KUBERNETES_NAMESPACE	namespace_name
KUBERNETES_POD_NAME	pod_name
KUBERNETES_CONTAINER_NAME	container_name
