TinyCDN is a simple Content Delivery Network (CDN) service implemented in Go. It supports caching with Redis, response compression with gzip, and includes monitoring integration with Prometheus.
- HTTP server with routing via Gin
- Large files are stored externally on MinIO object storage
- Caching layer backed by Redis for fast content delivery
- Gzip compression to reduce bandwidth usage
- Prometheus metrics for monitoring
- Fully containerized with Docker and Docker Compose

- Used xxHash for generating redis keys, leveraging its extremely fast and efficient hashing performance.
- Gained practical experience with gzip compression, understanding the trade-offs between server CPU load and client bandwidth savings.
- Learned how to configure and work with MinIO and its policies. Discovered the advantages of its S3 compatibility, making it a convenient choice for development.
- Learned a bit about Docker best practices and corrected mistakes, such as avoiding copying the .env file into the image.
- Learned about Redis key eviction policies and selected
allkeys-lrubased on the system requirements. This ensures that if a key without TTL is ever added, it can still be evicted, unlikevolatile-lru, which only applies to keys that have the expire field set to true. - Discovered the Viper package and used it to improve configuration management.
- Wrote a Bash script for the first time to simplify the build, run, and configuration processes.
I started this project to get hands-on experience with Go and to learn how to cache and serve static files. I’d love to see contributions from others!
