10 Steps to Build Your Private AI Image Generator with Docker and Open WebUI

We’ve all been there: you need to generate a few images for a project, you fire up an AI image service, and suddenly you’re wondering what happens to your prompts, how many credits you have left, or why that “safe content” filter rejected your perfectly reasonable request for a dragon wearing a business suit. What if you could skip all of that and run the whole thing on your own machine, with a slick chat UI on top? That’s exactly what Docker Model Runner now makes possible. With a couple of commands you can pull an image-generation model, connect it to Open WebUI, and start generating images right from a chat interface—fully local, fully private, fully yours. Let’s build it. Your own private DALL-E, no cloud subscription required. Follow these 10 steps to get started.
