我已经在由kubeadm制作的多节点kubernetes集群上部署了prometheus 2.0。在访问prometheus仪表板时,即使在prometheus配置yaml文件中配置后,我也无法查看pod和服务作业。 prometheus目标如下https://i.stack.imgur.com/jiQPG.png。这个问题与prometheus版本有什么关系吗?我想我的配置语法部分出了问题。

谢谢
我假设您正在执行您在评论中发布的查询:
container_memory_usage_bytes{job="kubernetes-pods"}
这不起作用,因为您按作业名称kubernetes-pods
过滤,但container_memory_usage_bytes
来自cAdvisor。因此,根据您的配置,该作业名为kubernetes-cadvisor
。
因此这应该工作:
container_memory_usage_bytes{job="kubernetes-cadvisor"}
由于系列名称相当独特,您可以省略作业名称:
container_memory_usage_bytes
