开发需求: 因系统程序部署时,经常是拆分部署(多台机器) ,手工部署费时费力,且每次都要手工配置系统参数(系统提供配置向导)。
如下图所示:
1)进行main容器 -> 2)执行系统配置向导 -> 3)选择服务器模式 -> 4) 选择web控制台....然后进行具体的服务器IP设置。
为了解放双手，用java实现了Linux(centos) 下docker 应用程序的命令交互。
具体代码如下:
import java.io.*;

特别注意:
private static String [] cmds = {"docker","exec","-i","main","bash"};
一定要使用 docker exec -i main bash ，不要使用 -it ，否则会报错 cannot enable tty mode on non tty input。
Usage: docker exec [OPTIONS] CONTAINER COMMAND [ARG...] Run a command in a running container -i, --interactive=false Keep STDIN open even if not attached -t, --tty=false Allocate a pseudo-TTY
打成jar包，执行jar包：
终于看到久违的部署成功界面~
