Jenkins报错

今天遇见了Jenkins报错无法启动，查看了rancher没有任何报错只是一直重启，所以手动启动了一个镜像

docker run -d -p 8002:8080 -v /data/docker/data/jenkins/jenkins_home:/var/jenkins_home --name jenkins-bak --restart=always jenkins:2.46.2

发现以下报错

根据第一行，报错得出，是协议问题，修改了config.xml

<?xml version='1.1' encoding='UTF-8'?>
#改为
<?xml version='1.0' encoding='UTF-8'?>

然后重启Docker镜像

docker restart jenkins-bak

问题解决，还没搞清楚为什么文件头会从1.1协议变成了1.0~
