+You should run a Kubernetes pod on every node. Example pod manifest:
+
+```
+apiVersion: v1
+kind: Pod
+metadata:
+  name: filebeat
+  namespace: kube-system
+  labels:
+    k8s-app: filebeat
+spec:
+  containers:
+  - name: filebeat
+    image: apsops/filebeat-kubernetes:v0.1
+    resources:
+      limits:
+        memory: 200Mi
+      requests:
+        cpu: 100m
+        memory: 200Mi
+    env:
+      - name: LOGSTASH_HOSTS
+        value: "'myhost.com:5000'"
+      - name: LOG_LEVEL
+        value: info
+    volumeMounts:
+    - name: varlog
+      mountPath: /var/log/containers
+      readOnly: true
+  terminationGracePeriodSeconds: 30
+  volumes:
+  - name: varlog
+    hostPath:
+      path: /var/log/containers
+```

 Make sure you add a filter in your logstash configuration if you want to process the actual log lines.
