Running N8N locally with Docker. Automation of image editing with google sheets

Описание: In this video, I show how I set up n8n locally for free using Docker and Docker Compose and build a real automation for AI makeup transfer.

The workflow takes two images (a girl without makeup and a reference image with makeup), automatically analyzes the makeup, generates a makeup prompt, and applies it using multiple AI models so you can compare results.

Everything runs locally, without paying for n8n, using only paid APIs where it actually makes sense.

🚀 What’s inside this video:

Local n8n setup with Docker (free)

Google Sheets as an input source

Converting Google Drive links into direct downloadable URLs

Uploading images to Wavespeed CDN

Image resizing with Google Nano Banana

Polling async API jobs until completion

Generating makeup prompts from reference images

Applying makeup using 3 different AI models

Comparing results (Google, OpenAI, ByteDance)

Pros & cons of n8n for automation

🧠 APIs & tools used:

n8n (self-hosted)

Docker & Docker Compose

Google Sheets API

Wavespeed API

Google Nano Banana (Pro)

OpenAI (custom Cloud Function)

ByteDance seedream

If you’re interested in AI automation, image processing, or building no-code/low-code pipelines, this video will give you a very practical, real-world example.
