FROM node:18-slim RUN apt-get update && apt-get install -y libpng-dev ... Limit memory to 512MB and CPU to 1 core. Set up a cron job that renews the CDN_API_KEY every 30 days. Store keys in a secrets manager (HashiCorp Vault, AWS Secrets Manager) instead of plain .env in production. Part 8: Frequently Asked Questions (FAQ) Q1: Is CDNMIMU free to use? It depends. Some CDNMIMU instances are open-source and self-hostable. Others are commercial. Check the bot’s license and the CDN’s pricing page. Q2: Can I install this bot on Windows? Yes. Use Node.js for Windows, install sharp via npm , and ensure libpng is available via vcpkg or by using the prebuilt binaries. Q3: How do I update the bot after the initial cdnmimu bot imagepng install ? git pull origin main npm install npm run migrate # if database changes exist npm restart Q4: The bot works but images are corrupted. What’s wrong? Likely a mismatch between the claimed PNG format and actual data. Run:
sudo apt-get install libpng16-16 npm rebuild sharp Cause: Expired or incorrect API key. Fix: Generate a new key from the CDNMIMU dashboard and update .env . Ensure no trailing spaces in the value.
