Kubernetes - How to deploy Filebeat on kubernetes?

Question

I would like to know how I can deploy a basic Filebeat pod on Kubernetes? I need to configure a .yaml file but I don't know what I need to specify:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: Filebeat
  labels:
    app: Filebeat
spec:
  replicas: 1
  selector:
    matchLabels:
      app: filebeat
  template:
    metadata:
      labels:
        app: filebeat
    spec:
      containers:
        - name: ???
          image: ???

Answer 1

Try deploy the filebeat component with the helm official chart, is very easy deploy and maintain (upgrade, change configuration) the app.

Btw if you decide deploy with a custom yaml, the current version for filebeat docker image is the 8.0.0, so your yaml example see like this:

spec:
  containers:
    - name: "filebeat"
      image: "docker.elastic.co/beats/filebeat:8.0.0-SNAPSHOT"

Answer 2

If you check filebeat-kubernetes.yaml from https://github.com/elastic/beats/blob/master/deploy/kubernetes/filebeat-kubernetes.yaml, you will see there already prepared values for you

apiVersion: apps/v1
kind: DaemonSet
metadata:
  name: filebeat
  namespace: kube-system
  labels:
    k8s-app: filebeat
spec:
  selector:
    matchLabels:
      k8s-app: filebeat
  template:
    metadata:
      labels:
        k8s-app: filebeat
    spec:
      containers:
      - name: filebeat
        image: docker.elastic.co/beats/filebeat:8.0.0
