Running Auditbeat on Kubernetes

Running Auditbeat on Kubernetes

edit

Auditbeat Docker images can be used on Kubernetes to check files integrity.

Kubernetes deploy manifests

edit

By deploying Auditbeat as a DaemonSet we ensure we get a running instance on each node of the cluster.

Everything is deployed under kube-system namespace, you can change that by updating the YAML file.

To get the manifests just run:

curl -L -O https://raw.githubusercontent.com/elastic/beats/6.4/deploy/kubernetes/auditbeat-kubernetes.yaml

If you are using Kubernetes 1.7 or earlier: Auditbeat uses a hostPath volume to persist internal data, it’s located under /var/lib/auditbeat-data. The manifest uses folder autocreation (DirectoryOrCreate), which was introduced in Kubernetes 1.8. You will need to remove type: DirectoryOrCreate from the manifest and create the host folder yourself.

Settings

edit

Some parameters are exposed in the manifest to configure logs destination, by default they will use an existing Elasticsearch deploy if it’s present, but you may want to change that behavior, so just edit the YAML file and modify them:

- name: ELASTICSEARCH_HOST
  value: elasticsearch
- name: ELASTICSEARCH_PORT
  value: "9200"
- name: ELASTICSEARCH_USERNAME
  value: elastic
- name: ELASTICSEARCH_PASSWORD
  value: changeme

Deploy

edit

To deploy Auditbeat to Kubernetes just run:

kubectl create -f auditbeat-kubernetes.yaml

Then you should be able to check the status by running:

$ kubectl --namespace=kube-system get ds/auditbeat

NAME       DESIRED   CURRENT   READY     UP-TO-DATE   AVAILABLE   NODE-SELECTOR   AGE
auditbeat   32        32        0         32           0           <none>          1m
