Adding tolerations to fluentbit pod and making it persistent
The tolerations attribute needs to be set on the pod, but you are attempting to set it on a container (that's why you see the error "unknown field "tolerations" in io.k8s.api.core.v1.Container"). You would need to write:
apiVersion: v1
kind: Pod
metadata:
  name: deployment
spec:
  volumes:
    - name: config_map_name
      configMap:
        name: config_map_name
    - name: pvc_name
      persistentVolumeClaim:
        claimName: pvc_name
  containers:
    - name: fluentbit-logger
      image: fluent/fluent-bit:2.1.3
      env:
        - name: FLUENTBIT_USER
          valueFrom:
            secretKeyRef:
              name: fluentbit-secret
              key: user
        - name: FLUENTBIT_PWD
          valueFrom:
            secretKeyRef:
              name: fluentbit-secret
              key: pwd
      resources:
        requests:
          memory: "32Mi"
          cpu: "50m"
        limits:
          memory: "64Mi"
          cpu: "100m"
      securityContext:
        runAsUser: 0
        privileged: true
      volumeMounts:
        - name: config_map_name
          mountPath: "/fluent-bit/etc"
        - name: pvc_name
          mountPath: mount_path
  tolerations:
  - key: "dedicated"
    operator: "Equal"
    value: "sgelk"
    effect: "NoSchedule"

  - key: "dedicated"
    operator: "Equal"
    value: "kafka"
    effect: "NoSchedule"


I am using fluentbit as a pod deployment where I am creating many fluentbit pods which are attached to azure blob containers. Since multiple pods exist I tried adding tolerations as I did on daemonset deployment but it did not work and failed. Also every time I delete and start the pods reinvests all the the again. Please advise on fixing these issues.

Getting the error as below
