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

Video Description

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. 👍 Like the video if it helped 💬 Ask questions in the comments 🔔 Subscribe for more automation & AI content ⏱️ Timestamps 00:00 – Intro & what this video is about 00:15 — Generation results in google sheets 00:57 – Wavespeed API overview 01:29 – Reviewing generated results 02:11 – n8n workflow overview (local setup) 02:34 – Google Sheets integration & authentication 03:06 – Docker & webhook configuration 04:18 – Getting rows from Google Sheets 04:34 – Selecting the last item with JavaScript 05:20 – Google Drive links problem explained 05:59 – Converting links to direct downloads 06:55 – Uploading images to Wavespeed CDN 07:54 – Image resizing with Google Nano Banana 08:16 – Polling API status until completion 09:00 – Why resizing images is important 10:08 – Generating makeup description (prompt) 10:29 – Why built-in AI nodes are not used 11:05 – Custom Google Cloud Function (OpenAI) 12:02 – Applying makeup with 3 AI models 12:56 – Saving results back to Google Sheets 13:09 – n8n pros & cons 13:46 – Final thoughts & outro
