The record

Purpose: Cantaloupe is an open-source dynamic image server that generates image derivatives on demand from high-resolution source images.
Image operations: Available image operations include cropping, scaling, and rotation, supporting deep-zoom viewers and on-the-fly thumbnails.
IIIF support: The server conforms to all IIIF Image API versions through 3.0.
Image sources: Images can be served from filesystems, HTTP or HTTPS servers, S3, Azure Storage, and relational database BLOBs.
Image processors: Processor options include Java 2D, JAI, TurboJPEG, Kakadu, OpenJPEG, Grok, FFmpeg, and PDFBox.
Caching: Cache options include filesystem, Java heap, JDBC, S3, Azure Storage, and Redis implementations.
Security features: The project lists dynamic selective image and text watermarking, image-region redaction, HTTPS, HTTP Basic authentication, and customizable authorization policies.
TLS configuration: HTTPS is configurable, using a signed X.509 certificate in a Java KeyStore or PKCS#12 keystore.
Configuration: Configuration uses key-value pairs from environment variables or a .properties file, and most file changes take effect without restarting.
Deployment requirement: The base requirement is Java 17, and optional sources, processors, or caches may have additional requirements.
Docker: The project says there is currently no official Docker image.
Support: The project directs questions and comments to GitHub Discussions and bug reports or feature requests to GitHub Issues.
Intended users: The documentation describes production deployment and tuning, including controls for limiting image scale, pixel size, request threads, and queue length.
Maker: The site copyright identifies the University of Illinois Board of Trustees.
