cpu count¶

grep -c ^processor /proc/cpuinfo #should agree with multiprocessing.cpu_count()

cpu settings¶

Threads = 2 does not mean the cpu requests should be 2. Should be tested?

The args section of the configuration file provides arguments for the container when it starts. The -cpus "2" argument tells the Container to attempt to use 2 CPUs.

apiVersion: v1
kind: Pod
metadata:
  name: cpu-2
  namespace: cpu-test
spec:
  containers:
  - name: cpu-ctr-2
    image: vish/stress
    resources:
      requests:
        cpu: 500m
      limits:
        cpu: "1"
    args:
    - -cpus
    - "2"
