Pods stuck in ContainerCreating and Running #1672

@awprice

Description

@awprice

Description of problem

When scheduling a large number of pods at once, e.g. 40+ at a time, most of the pods transition from Pending -> ContainerCreating -> Running -> Completed, but a large number of them will either get stuck in ContainerCreating or Running.

The process inside the pod is a simple sleep 5 and should finish quite quickly, but we see pods stay running for multiple minutes or indefinitely.

We see the containerd-shim-kata-v2 consuming large amounts of CPU when this is occurring, see output of top below.

Expected result

Pods to only be in the Running state for 5 seconds and then transition to Completed.

Actual result

Pods get stuck in either the Running state or ContainerCreating state, and either stay in that state indefinitely or eventually transition to Completed.

We see the following side effects of this:

  • CNI IP addresses can be exhausted
  • containerd-shim-kata-v2 consumes large amounts of CPU
  • Init containers don't complete

The output of kubectl get pods shows pods running for much longer than 5 seconds:
We used the pod script below to create two sets of 40 pods.

Pod Spec

We are using the following bash script to generate pods that sleep:

#!/bin/bash

template=$(cat <<EOF
apiVersion: v1
kind: Pod
metadata:
  namespace: default
  generateName: sleep-
  labels:
    app: sleep
  annotations:
    io.kubernetes.cri.untrusted-workload: "true"
spec:
  nodeSelector:
    customer: kata
  tolerations:
    - operator: Exists
  restartPolicy: Never
  containers:
  - name: sleep
    image: alpine:3.7
    command: ["sleep", "5"]
    resources:
      limits:
        cpu: "1000m"
        memory: "1024Mi"
---
)

rm -f /tmp/sleep-pod.yaml
for ((n=0;n<$1;n++))
do
  echo "$template" >> /tmp/sleep-pod.yaml
done
kubectl create -f /tmp/sleep-pod.yaml

Invoked with: ./generate-pods.sh <number-of-pods>
<number-of-pods> being the number of pods you want to generate.

Additional Details

  • We are using an AWS i3.metal instance
  • We are using Kubernetes 1.13.5
  • The only thing we have modified in Kata configuration.toml is enabling debug - enable_debug = true
