Efficient DevOp Tooling with Java and GraalVM
summary
Claims that Java can be a first-class DevOps toolchain using GraalVM native image to produce fast, standalone CLIs and operators. Uses picocli, the Java Kubernetes client, Gradle and native-image; demo compiles a CLI into a ~26 MB binary in ~30–40s and preserves help, tab completion and ANSI colors. Builds three operators (killport chaos operator, sealed-secrets style operator, microservice operator) that run but require a reflection configuration or an agent pass to resolve reflective libraries. Polyglot support for Python/Ruby on the JVM is shown as a bonus.
