问题是什么基于以下配置，我执行了2个测试用例：

1.我使用我指定的图像，有2个容器将在同一个pod中创建，包括我的定义容器，jenkins kubernetes插件将自动创建一个JNLP容器，但实际命令在JNLP容器中运行，而不是在我指定的容器中。
1.我尝试扩展jnlp-slave映像（从office站点获取），kubenetes插件页面中的容器名称为“jnlp”（图像是由office docker文件“https://hub.docker.com/r/jenkins/jnlp-slave/~/dockerfile/“构建的），我首先让基本jenkins/slave图像工作良好，然后尝试根据需要扩展它。但当我尝试使用默认图像时，它总是提示“等待代理连接（1/100）“，似乎是等待JNLP客户端连接，我进入由jenkins kubernetes插件创建的动态图像，我发现没有任何进程关系到“ENTRYPOINT [“jenkins-slave”]"，我检查了jenkins日志，它提示下面的信息。将非常高兴的任何提示。

Jenkins Version :Jenkins ver. 2.138

Jenkins kubernetes Plugin : 1.12.3

我所做的：

1. Kubernetes集群运行良好
2. Jenkins主服务器独立于Kubernetes群集。
3. Jenkins kubernetes插件成功获取kubernetes证书和连接测试。
   1.添加了带有POD标记的kubernetes云。
   1.通过“限制此项目可以运行的位置”将标签与Jenkins的任务相结合

FROM jenkins/slave:3.23-1-alpine

LABEL Description="This is a base image, which allows connecting Jenkins agents via JNLP protocols" Vendor="Jenkins project" Version="3.23"

COPY jenkins-slave /usr/local/bin/jenkins-slave

ENTRYPOINT ["jenkins-slave"]

如何触发作业：

Jenkins通过curl命令触发作业（不在管道中），jenkins kubernetes插件可以用我定义的图像触发作业。
