一键发版多节点

一键

• 新增多节点一键滚动发版多节点，多个节点间隔25秒。
• 一键发版新增build pom文件失败时，自动终止。
• 一键发版是滚动单一节点发版，不是多个节点一起发版。
• 一键发版时，第一个节点发版失败，不会进行下一个节点发版。
• 一键发版新增，发版成功后自动打包代码到code仓库功能（自动打tag号提交到code里，如需回滚时，选择tag号自动回滚即可）
• 一键发版里的tag号，可以在单节点应用上使用。
• 一键发版弃用单节点，手动回滚功能。
• 一键回滚时选择最近的p开头tag号回滚即可。
•  目前生产已改造完。
• 图中配置文件内容deploy.ymal

Jenkins建立maven项目配置

丢弃旧的构建，输入如下即可

配置构建时的分支，如没有Git Paranmeter插件，自行在插件中安装即可。

配置代码仓库地址，关于认证，参考博客里的Jenkins结合code

Java应用deploy到maven私有仓库，Build是代码中的pom文件构建参数

maven编译打包失败后，终止操作，以及打包成功后做代码分发。

使用Post build task插件，在发版成功后自动打tag号上传到代码仓库，方便回滚时，直接选择tag号回滚即可。

自动打tag号代码

echo "$branch"
master='origin/master'
if [ $branch == $master ]
then
/usr/bin/git tag -a p_$BUILD_NUMBER -m "commit:$GIT_COMMIT"
/usr/bin/git push origin p_$BUILD_NUMBER 
/usr/bin/git tag -d p_$BUILD_NUMBER 
fi
