pod resources are not honoured in pod config file

[devimc]

Description of problem

using constraints, pod vCPus and Memory are always 0 in kubernetes

run a container with kubernetes and take a look to the pod config file

kubectl --namespace=sandbox create -f ~/debian.yaml
cat /var/lib/virtcontainers/pods/$ID/config.json
... "VMConfig":{"VCPUs":0,"Memory":0}

debian.yaml

apiVersion: v1
kind: Pod
metadata:
  name: test
spec:
  containers:
  - name: test1
    image: debian
    resources:
      limits:
        cpu: "4"
    args: [ nproc ]
    tty: true
  - name: test2
    image: debian
    args: [ echo, "bye world!" ]
  - name: test3
    image: debian
    resources:
      limits:
        cpu: "3"
    args:
    - bash
    stdin: true
    tty: true

do the same, but using docker

docker run -dti --cpus=5 debian bash
cat /var/lib/virtcontainers/pods/$ID/config.json
... "VMConfig":{"VCPUs":5,"Memory":0}

Expected result

resources should not be 0 in the pod configuration

I'm seeing the values showing as zero under docker too:

$ sudo jq -S '.VMConfig?' /var/lib/virtcontainers/pods/a4312f7ffab2cb385442eaa44903d0307a5a4a413868bf416d5e20d82fbdb543/config.json                               
{                                                                                                                                                                                             
  "Memory": 0,
  "VCPUs": 0
}

@jodh-intel ohh you're right, I forgot to mention that you have to use constrains

docker run -dti --cpus=5 debian bash
