Kubernetes pod and service not showing in prometheus target

Question

I have deployed prometheus 2.0 on my multi node kubernetes cluster made from kubeadm. While accessing the prometheus dashboard i am not able to view pods and service job even after configuring it in prometheus configuration yaml file. prometheus target are as follow https://i.sstatic.net/jiQPG.png . Does this problem has anything to do with the prometheus version. I think i am going wrong with the syntax part of the configuration.

I assume you are doing the query you posted in the comments:

container_memory_usage_bytes{job="kubernetes-pods"}

This doesn't work, because you are filtering by the job name kubernetes-pods, but container_memory_usage_bytes comes from cAdvisor. So according to your config the job is named kubernetes-cadvisor.

Therefore this should work:

container_memory_usage_bytes{job="kubernetes-cadvisor"}

Since the series name is rather unique, you can just omit the job name:

container_memory_usage_bytes
