This one handles the messy intersection of Java and Docker containers, which is trickier than it looks. It covers multi-stage builds with proper layer caching, JVM container flags like MaxRAMPercentage and UseContainerSupport, and Spring Boot layered JARs. You'll want this when you're tired of bloated images or dealing with OOMKilled containers because the JVM didn't respect memory limits. The base image comparison (temurin vs distroless vs alpine) is actually useful, and it includes security hardening with non-root users and read-only filesystems. Bonded to the java-devops agent, so it knows both Maven/Gradle build contexts and container orchestration.
