A fast image processing server that resizes, crops and converts images on the fly from signed URLs. Apache-2.0 licensed. A signing key and salt are generated for you, so only URLs signed with them are served. This page describes the Levelrail template for imgproxy (Infrastructure). It deploys the services below as one Docker Compose app on your own server. Project site: https://docs.imgproxy.net/. Recommended memory: about 256 MiB.
