[Windows 10 和 MAC] 尝试使用分布式测试在 docker 上运行空手道测试用例，但未按预期工作，并且在工作节点上出现错误。
错误：

使用上述网站上提到的作业服务器示例项目。https://github.com/intuit/karate/tree/develop/examples/jobserver
使用的命令：
docker run --network=karate --name karate --cap-add=SYS_ADMIN -w /src karate bash mvn clean test -Dtest=WebDockerJobRunner
docker run -d --network=karate --rm --cap-add=SYS_ADMIN -e KARATE_JOBURL=http://karate:9080 karate
