Java Container Mastery: Optimizing Images Across Build Tools

In today's cloud-native landscape, containerizing Java applications has become a standard practice, but the path to optimal implementation remains unclear. This presentation dissects the various approaches to containerizing Java applications beyond the basic Dockerfile.

We'll examine the strengths and limitations of multiple container creation methods: traditional Dockerfiles, multi-stage Dockerfiles, Cloud-Native Buildpacks (buildpacks.io/paketo.io), Google's Jib, and custom solutions using jdeps and jlink. Each approach will be evaluated through our comprehensive ""5 S"" criteria:

Speed: Build efficiency Size: Image optimization and footprint reduction Structure: Organization and standardization capabilities Simplicity: Ease of implementation and maintenance Security: Vulnerability management and protection

Through live demonstrations focusing primarily on modern Java frameworks (Spring Boot, Quarkus, and Micronaut), attendees will gain practical insights into selecting the right containerization strategy for their specific use cases. We'll also explore how GraalVM native image compilation introduces new considerations and opportunities for Java containerization.

While Java implementations serve as our primary examples, the principles discussed apply broadly across language ecosystems. Join this session to transform your containerization practices from merely functional to truly optimized for production environments."
