The Python layer manages container lifecycle and simulates network failures via iptables. + +--- +## Write a Java Application (if needed) Review Comment: Intentional: the Java section is marked "(if needed)" — readers who only need a Python wrapper can skip it. The Python test references the Java class by `java_class_name`, so it makes sense to see what Java class you're wiring in before writing the Python side. -- This is an automated message from the Apache Git Service.
