is possible to convert a Spring Boot fat jar into a docker image with just a few lines in the Dockerfile, we will use the layering feature to create an optimized docker image. When you create a jar containing command can be used to easily split the application into layers to be added to the dockerfile. Here’s an example of a Dockerfile using jarmode. 228 FROM adoptopenjdk:11-jre-hotspot as builder WORKDIR application ion/ ./ ENTRYPOINT ["java", "org.springframework.boot.loader.JarLauncher"] Assuming the above Dockerfile is in the current directory, your docker image can be built with docker build ., or optionally
