This blog post focuses on optimizing the size of JVM Docker images. It explores various techniques such as multi-stage builds, jlink, jdeps, and experimenting with base images. By implementing these optimizations, deployments can be faster, and resource usage can be optimized.

The Problem

Since Java 11, there is no pre-bundled JRE provided. As a result, basic Dockerfiles without any optimization can result in large image sizes. In the absence of a provided JRE, it becomes necessary to explore techniques and optimizations to reduce the size of JVM Docker images.
