To ensure that your workload runs on Exostellar nodes scheduled by the Exostellar Karpenter and block Karpenter from voluntarily disrupting your workload, you need to set affinity settings and annotations in your workload YAML file. Below is an example of how to modify your YAML file to include these settings:

Code Block
languageyaml
apiVersion: apps/v1
kind: PodDeployment
metadata:
  name: my-nginx
  annotations:: nginx
spec:
  selector:
    matchLabels:
      app: nginx
  replicas: 1
  template:
    metadata:
      labels:
        app: nginx
    spec:
      tolerations:
      - karpenterkey: "exokarpenter.sh/do-not-disruptx-compute"
        operator: "trueExists"
spec:
        effect: "NoSchedule"
      affinity:
        nodeAffinity:
          requiredDuringSchedulingIgnoredDuringExecution:
            nodeSelectorTerms:
            - matchExpressions:
              - key: karpenterexokarpenter.sh/nodepool
                operator: In
                values:
                - pool-a
      containers:
      - name: nginx
        image: nginx:1.14.2
        ports:
        - containerPort: 80
        resources:
            requests:
              cpu: 1
