Setup securityContext inside kubernetes deployment

I'm using a nfs mounted volume in my deployments. I need to give it the fsGroup like below:

securityContext:
  runAsUser: 1000
  runAsGroup: 3000
  fsGroup: 2000

Is there a way to make this on the deployment manifest? As I can see on the documentation I can set the securitycontext in the pod yaml only.

You can use the securityContext in Deployment in the same way you use it inside Pod.

Like it was already suggested by placing it under template.spec:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: test-deployment
  labels:
    app: test
spec:
  replicas: 3
  selector:
    matchLabels:
      app: test
  template:
    metadata:
      labels:
        app: test
    spec:
      securityContext:
          runAsUser: 2000
          runAsGroup: 3000
          fsGroup: 2000
      containers:
      - name: test
        image: busybox
        ports:
        - containerPort: 80
        command: [ "sh", "-c", "sleep 1h" ]

And you can test it:

$ kubectl exec -it test-deployment-54d954d7f-2b582  sh
/ $ ps
PID   USER     TIME  COMMAND
    1 2000      0:00 sleep 1h
    6 2000      0:00 sh
   11 2000      0:00 ps
/ $ whoami
whoami: unknown uid 200
