构建应用程序镜像
[root@k8s02 app]# docker build --build-arg JAR_NAME=`ls target/*.jar` -t saas:v2 .
[root@k8s02 app]# docker run -itd saas:v2
[root@k8s02 app]# docker exec -it beautiful_dewdney /bin/bash
[root@a0d4d3121c9a data]# ls
Dockerfile nohup.out saas.jar start.sh
测试安装的ping命令，有时候在容器内会使用到ping功能
[root@a0d4d3121c9a data]# ping 192.168.1.59
