<!-- Answer --> Here’s a step-by-step guide to enable thumbnail generation in Superset 4.1.1 with Docker: 1. **Open the file `docker/.env` in your Superset project folder.** Find these lines and change them to: ``` ENABLE_PLAYWRIGHT=true INCLUDE_CHROMIUM=true ``` (If `INCLUDE_CHROMIUM` isn’t there, add it.) 2. **Save the file.** 3. **Rebuild your Docker images.** In your terminal, run: ``` docker-compose build ``` This step is important! It makes sure Playwright and Chromium are actually installed in your containers. 4. **Restart your containers.** Run: ``` docker-compose up -d ``` This will start everything with the new settings. 5. **Check that Chromium is installed.** Enter your worker container: ``` docker-compose exec superset_worker bash ``` Then run: ``` playwright show-browser chromium ``` If you see information about Chromium, it’s installed correctly. If you see an error, something went wrong with the build. 6. **Make sure Redis is running** (since you use it for thumbnail caching). 7. **Try generating a thumbnail again in Superset.** If thumbnails still don’t show up, check the logs for errors: ``` docker-compose logs superset_worker ``` Look for messages about Playwright or Chromium. That’s it! These steps should get thumbnails working in your Docker-based Superset setup. If you need more help, let me know which step you get stuck on.
