1- create a pod that defines twice the same environment variable
```
apiVersion: v1
kind: Pod
metadata:
  labels:
    test: liveness
  name: liveness-exec
spec:
  nodeName: prd-ne-shop03-84q98-ssp-arm64-northeurope3-8bpm5
  containers:
  - name: liveness
    env:
    - name: toto
      value: tata
    - name: toto
      value: tata
    image: centos
    args:
    - /bin/sh
    - -c
    - sleep 7200
  tolerations:
  - effect: NoSchedule
    key: cpu
    value: arm64
  - effect: NoSchedule
    key: reservedFor
    value: ssp-arm64
```

2- delete the node and machine where the pod runs
3- verify that the pod still shows as ready (Kubernetes bug)

Pod still shows as ready

Pod is removed
