A 1.5MB Java Container App? Yes you can!
Tools-in-Action (INTERMEDIATE level)
Taroudant A

Containers are increasing the way Java applications are packaged and deployed. There are lots of qualities desirable in a containerized application like fast startup and low memory and CPU requirements, but size and security are also important considerations. Moving big container images around a network will increase the time it takes to start up a new K8s pod or launch a container, and "just enough operating system" container images with reduced attack surface area are also preferable. So what’s the smallest possible Java container image? In this session we’ll demonstrate how to build containerized Java applications small as a mere 1.5MB! Using GraalVM Native Image ahead-of-time compilation and static linking with musl libc we can shrink down and strip out all the unnecessary bits that bloat a typical Java apps and deploy them in lightweight and security focused container images like Alpine and distroless–even scratch!
