我遇到了从pod无法连接到Jenkins master的问题。
这是Jenkins构建输出
[Pipeline] Start of Pipeline
[Pipeline] podTemplate
[Pipeline] {
[Pipeline] node
Still waiting to schedule task
‘ci-xprj2-2z8qp’ is offline我可以在Jenkins豆荚日志里看到这个

有人帮忙吗？
2条答案
按热度按时间kxxlusnw1#
看起来要关注的错误是：
也就是
jenkins1can't be resolvedjenkins1对应于Kubernetes服务名称，我会仔细检查其名称和详细信息，然后在名称空间中启动另一个pod，让它休眠一段时间，以便您可以执行并查看是否可以解析jenkins1。jenkins1对应于你有时在公司看到的一个单词域名，那么我会在你的pod中仔细检查你在/etc/resolv.conf中的搜索前缀：j2datikz2#
但你仍然会遇到这个问题：“还在等待调度任务pod_name离线”，简单地把kubernetes插件更新到最新版本，就解决了我的问题
