Hey @Tara, this is how you use taints and tolerance in yaml:

apiVersion: extensions/v1beta1
kind: DaemonSet
metadata:
  name: dd-agent
spec:
  template:
    metadata:
      labels:
        app: dd-agent
      name: dd-agent
    spec:
      tolerations: 
      - key: node-role.kubernetes.io/master
        effect: NoSchedule
      containers:
      - image: datadog/docker-dd-agent:latest
        imagePullPolicy: Always
        name: dd-agent
        ports:
          - containerPort: 8125
            name: dogstatsdport
            protocol: UDP
        env:
          - name: API_KEY
            value: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAaaaaaaaaa
          - name: KUBERNETES
            value: "yes"
          - name: SD_BACKEND
            value: docker
        resources:
          requests:
            memory: "128Mi"
            cpu: "100m"
          limits:
            memory: "512Mi"
            cpu: "250m"
        volumeMounts:
          - name: dockersocket
            mountPath: /var/run/docker.sock
          - name: procdir
            mountPath: /host/proc
            readOnly: true
          - name: cgroups
            mountPath: /host/sys/fs/cgroup
            readOnly: true
      volumes:
        - hostPath:
            path: /var/run/docker.sock
          name: dockersocket
        - hostPath:
            path: /proc
          name: procdir
        - hostPath:
            path: /sys/fs/cgroup
          name: cgroups
