docker jenkins 安装插件导致jenkins升级版本回退

Posted 2022-11-01

1、场景

同事要使用api token插件导致jenkins自动升级无法正常启动。jenkins属于sre的CD部分，一挂无法发版，十万火急。升级后启动报错内容如下:

docker logs -f jenkins-id

//插件启动失败

SEVERE  h.model.UpdateCenter$DownloadJob#run: Failed to install jaxb

//jenkins需要jdk 11 或者 17

Jenkins requires Java versions [17, 11] but you are running with Java 1.8 from /opt/java/openjdk/jre
java.lang.UnsupportedClassVersionError: 52.0

2、jenkins是特定的版本并且内置配置信息，最好的方法是还原至原来的版本。

思路: jenkins不论是docker还是war包启动名字为 jenkins.war，需要找到还原原来的版本

通过目录id反查服务

3、启动jenkins

#重启
docker restart docker-jenkins-id
#查看状态
docker ps -a | grep jenkins | grep Up

 观察日志，不报错并且状态Up，不在restarting
