jenkins项目回滚

 

 

 abc是backup_versioni文件里面的key，文件内容格式：abc=x1,x2,x3，其中x1-x3是备份文件名

 

 

 parameters {

extendedChoice description: '请选择要回滚的版本号', multiSelectDelimiter: ',', name: 'rollback', propertyFile: '/var/jenkins_home/backup_version', propertyKey: 'abc', quoteValue: false, saveJSONParameterToFile: false, type: 'PT_SINGLE_SELECT', visibleItemCount: 5
}

 

下面是备份文件的格式，不加时间是为了怕两台web时间不一致： 

 

 demo-ROOT-$(date +%F)-{{ build_number }}.war

把备份文件写进去备份版本记录文件：

ls /data/backup/|awk 'BEGIN{printf "abc="}{printf $0","}' > /tmp/backup_version

 

 需要在之前发布的java项目里面的代码加上：1、登录jenkins114的凭据，虽然也可以用密钥，但由于多台web访问jenkins，所以改为用密码，凭据是生成114服务器的密码的；2、114的ip和用户和密码的变量，这个变量数值来自于第一步的凭据；3、加上生成版本文件记录的文件拷贝并通过sshpass拷贝到114去：

pipeline {
agent {
label "web2"
}
environment {
ansible_ssh_auth = "393ee6f0-68cd-4b5b-b6c2-4656ca1286e8"
}
parameters {
extendedChoice description: '请选择要回滚的版本号', multiSelectDelimiter: ',', name: 'RollbackVersion', propertyFile: '/var/jenkins_home/backup_version', propertyKey: 'abc', quoteValue: false, saveJSONParameterToFile: false, type: 'PT_SINGLE_SELECT', visibleItemCount: 5
choice choices: ['webservers1', 'webservers2', 'webservers3'], description: '请选择主机组', name: 'ENV'
}
stages {
stage('拷贝备份文件到远程主机并部署') {
steps {
