回滚流程

版本手工设置

#宿主机的/opt/jenkins_home和容器的/var/jenkins_home是持久化映射
[root@bogon ~]# cd /opt/jenkins_home/
[root@bogon jenkins_home]# vi backup_version
abc=1,2,3

}

回滚版本效果

按版本号排序并取5个最近版本

[root@bogon backup]# ls /data/backup/ |sort -t - -k 6 -nr
demo-ROOT-2021-10-24-17.war
demo-ROOT-2021-10-24-16.war
demo-ROOT-2021-10-23-15.war
[root@bogon backup]# ls /data/backup/ |sort -t - -k 6 -nr |awk 'BEGIN{printf "abc="}{printf $0","}'
abc=demo-ROOT-2021-10-24-17.war,demo-ROOT-2021-10-24-16.war,demo-ROOT-2021-10-23-15.war,

[root@bogon backup]# ls /data/backup/ |sort -t - -k 6 -nr |head -n5 |awk 'BEGIN{printf "abc="}{printf $0","}' > /tmp/backup_version
[root@bogon backup]# cat /tmp/backup_version 
abc=demo-ROOT-2021-10-24-17.war,demo-ROOT-2021-10-24-16.war,demo-ROOT-2021-10-23-15.war,

将生成的版本号远程发送到jekins服务器

sshpass 工具需要安装，ansible自带

#sshpass 工具需要安装，ansible自带
[root@gitlab backup]# yum install sshpass

[root@bogon backup]# ls /data/backup/ |sort -t - -k 6 -nr |head -n5 |awk 'BEGIN{printf "abc="}{printf \$0","}' > /tmp/backup_version
[root@bogon backup]#sshpass -p"root" scp  -o StrictHostKeyChecking=no /tmp/backup_version root@192.168.153.19:/opt/jenkins_home/
