修改脚本权限与用户，以后会以docker用户调用：

sudo chmod -x deploy-docker-tomcat.sh
sudo chown -R docker:docker deploy-docker-tomcat.sh

Jenkins插件

• 版本管理工具插件，如git
• 构建工具，Maven
• 发布时通过SSH连接，要Publish Over SSH 和 SSH plugin

Jenkins 构造war包后上传

在「构建后操作」添加「Send build artifacts over SSH」：

• Name：dest host
• Source Files：target/*.war
• Remove prefix：target/
• Remote directory：/war/$project_name
• Exec command：/data/dockerfiles/scripts/deploy.sh \(project_name hello_docker \)release_branch 11000 8080
