Question

我已经成功在ubuntu 16.04上设置了jenkins，没有出现如下情况：

docker run -p 8080:8080 --name=jenkins-master jenkins/jenkins

但是，当我尝试使用以下命令在docker swarm中设置jenkins时：

docker service create --name jenkins -p 8080:8080 jenkins/jenkins:lts-alpine

容器和图像已创建，但是当我进入服务日志时，它具有以下错误：

我的解决方案是以下之一： 1.删除/etc/resolv.conf中的“搜索”，然后再次运行jenkins服务。 2.在詹金斯CMD中配置该选项。 -Dhudson.DNSMultiCast.disabled = true -Dhudson.udp = -1

在swarm中自动执行jenkins docker安装程序时出错
