Today we are announcing chiseled containers for OpenJRE 8, 17 and 21 (Open Java Runtime Environment), coming from the OpenJDK project. These images are highly optimized for size and security, containing only the dependencies that are strictly necessary. They are available for both AMD64 and ARM64 architectures and benefit from 12 years of security support.
