Beginner’s Tutorial: Manage Google Cloud Storage Buckets and Objects with n8n Watch the demo video below: Who’s it for Beginners who want to learn how to automate Google Cloud Storage (GCS) operations with n8n. Developers who want to combine AI image generation with cloud storage management. Anyone looking for a simple introduction to working with Buckets and Objects in GCS. How it works / What it does This workflow demonstrates end-to-end usage of Google Cloud Storage with AI integration: Trigger: Start manually by clicking Execute Workflow. Edit Fields: Provide input values (e.g., bucket name or image description). List Buckets: Retrieve all existing buckets in the project (branch: view only). Create Bucket: If needed, create a new bucket to store objects. Prompt Generation Agent: Use an AI model to generate a creative text prompt. Generate Image: Convert the AI-generated prompt into an image. Upload Object: Store the generated image as an object in the selected bucket. Delete Object: Clean up by removing the uploaded object if required. This shows the full lifecycle: Bucket → Object (Create/Upload/Delete) combined with AI image generation. How to set up Trigger the workflow: Use the When clicking Execute workflow node to start manually. Provide inputs: In Edit Fields, specify details such as bucket name or description text for the image. List buckets: Use the List Buckets node to see what exists. Create a bucket: Use Create Bucket if you want a new storage bucket. Generate prompt & image: The Prompt Generation Agent uses an OpenAI Chat Model to create an image prompt. The Generate an Image node turns this prompt into an actual image. Upload to bucket: Use Create Object to upload the generated image into your GCS bucket. Delete object (optional): Use Delete Object to remove the file from the bucket as a cleanup step. Requirements An active Google Cloud account with Cloud Storage API enabled. A Service Account Key (JSON) credential added in n8n for GCS. An OpenAI API Key configured in n8n for the prompt and image generation nodes. Basic familiarity with running workflows in n8n. How to customize the workflow Different object types:** Instead of images, upload PDFs, logs, or text files. Automatic cleanup:** Skip the delete step if you want objects to persist. Schedule trigger:** Replace manual execution with a weekly or daily schedule. Dynamic prompts:** Accept user input from a form or webhook to generate images. Multi-bucket management:** Extend the logic to manage multiple buckets across projects. Notifications:** Add a Slack/Email step after upload to notify your team with the object URL. ✅ By the end of this tutorial, you’ll understand how to: Work with Buckets (list, create). Work with Objects (upload, delete). Integrate AI image generation with Google Cloud Storage.

Reliable Backup & Sync Execution Validation (Log-Driven) This workflow monitors filesystem sync and backup jobs by validating their execution logs, not by running or inspecting the jobs themselves. After purchase, you will receive a complete package including: workflow.json** – ready to be imported into n8n Shell script templates (.sh)** – reference sync job templates designed to generate structured logs fully compatible with the workflow Complete setup documentation** – step-by-step guide covering configuration, deployment, and operational requirements How it works (high level) Sync jobs are executed externally using standardized shell templates: rsync_job-Template.sh rclone_job-Template.sh Each job produces one deterministic log file per run Logs are uploaded daily to Google Cloud Storage This workflow runs on a schedule and: Verifies that all expected logs exist for the day (UTC) Optionally inspects their contents Sends alerts if logs are missing or report failures Key design principles Log-driven monitoring** (evidence-based, not assumption-based) One job = one log = one source of truth** No SSH, no server access, no execution coupling** Safe to run in untrusted or restricted environments Logging contract (required) Each log file must contain the following lifecycle events, in order: event=START event=RSYNC_END or event=RCLONE_END event=SUMMARY event=END If the END event is missing, the job is considered failed or interrupted. Configuration Expected jobs and log filenames are defined in sync-jobs.json. This workflow only validates presence and state of logs — it never assumes job success.
