/kind bug

/sig node
/area kubelet
/area kubelet-api

What happened:
We are trying to migrate from docker to cri-o for container runtime

When querying the kubelet for /stats/summary (curl localhost:10255/stats/summary)
the pods information is an empty list although pods are running on the node, the general server information is available.
This is an example of the end of the output:
"rlimit": {
"time": "2018-10-11T06:38:33Z",
"maxpid": 40960,
"curproc": 1972
"pods": []

What you expected to happen:
statics information on pod

How to reproduce it (as minimally and precisely as possible):
not sure, here is our kubelet configuration:
xecStart=/usr/bin/kubelet --allow-privileged=true

Anything else we need to know?:
We've got the same results with mix of the following configuration:

  • kubelet 1.10.7 and 1.11.3
  • cri-o 1.10.5 and 1.11.6

Another issue that we have that I think is the result of this is that crictl stats does not return any information


  • Kubernetes version (use kubectl version): 1.11.3
  • Cloud provider or hardware configuration: on premise Dell 630/640 servers
  • OS (e.g. from /etc/os-release): centos 7
  • Kernel (e.g. uname -a): Linux 4.14.35-1818.2.1.el7uek.x86_64 #2 SMP Mon Aug 27 21:16:31 PDT 2018 x86_64 x86_64 x8 6_64 GNU/Linux
  • Install tools: puppet automation
  • Others:
