Obtaining Packetbeat for Docker is as simple as issuing a
docker pull command
against the Elastic Docker registry.
However, version 8.9.0 of Packetbeat has not yet been released, so no Docker image is currently available for this version.
You can use the Cosign application to verify the Packetbeat Docker image signature.
Version 8.9.0 of Packetbeat has not yet been released, so no Docker image is currently available for this version.
Running Packetbeat with the setup command will create the index pattern and load visualizations , dashboards, and machine learning jobs. Run this command:
docker run \ --cap-add=NET_ADMIN \ docker.elastic.co/beats/packetbeat:8.9.0 \ setup -E setup.kibana.host=kibana:5601 \ -E output.elasticsearch.hosts=["elasticsearch:9200"]
Substitute your Kibana and Elasticsearch hosts and ports.
If you are using the hosted Elasticsearch Service in Elastic Cloud, replace
-E cloud.id=<Cloud ID from Elasticsearch Service> \ -E cloud.auth=elastic:<elastic password>
The Docker image provides several methods for configuring Packetbeat. The conventional approach is to provide a configuration file via a volume mount, but it’s also possible to create a custom image with your configuration included.
Download this example configuration file as a starting point:
curl -L -O https://raw.githubusercontent.com/elastic/beats/master/deploy/docker/packetbeat.docker.yml
One way to configure Packetbeat on Docker is to provide
packetbeat.docker.yml via a volume mount.
docker run, the volume mount can be specified like this.
docker run -d \ --name=packetbeat \ --user=packetbeat \ --volume="$(pwd)/packetbeat.docker.yml:/usr/share/packetbeat/packetbeat.yml:ro" \ --cap-add="NET_RAW" \ --cap-add="NET_ADMIN" \ --network=host \ docker.elastic.co/beats/packetbeat:8.9.0 \ --strict.perms=false -e \ -E output.elasticsearch.hosts=["elasticsearch:9200"]
packetbeat.docker.yml downloaded earlier should be customized for your environment. See Configure for more details. Edit the configuration file and customize it to match your environment then re-deploy your Packetbeat container.
It’s possible to embed your Packetbeat configuration in a custom image. Here is an example Dockerfile to achieve this:
FROM docker.elastic.co/beats/packetbeat:8.9.0 COPY --chown=root:packetbeat packetbeat.yml /usr/share/packetbeat/packetbeat.yml
Required network capabilitiesedit
Under Docker, Packetbeat runs as a non-root user, but requires some privileged
network capabilities to operate correctly. Ensure that the
capability is available to the container.
docker run --cap-add=NET_ADMIN docker.elastic.co/beats/packetbeat:8.9.0
Capture traffic from the host systemedit
By default, Docker networking will connect the Packetbeat container to an
isolated virtual network, with a limited view of network traffic. You may wish
to connect the container directly to the host network in order to see traffic
destined for, and originating from, the host system. With
docker run, this can
be achieved by specifying
docker run --cap-add=NET_ADMIN --network=host docker.elastic.co/beats/packetbeat:8.9.0
On Windows and MacOS, specifying
--network=host will bind the
container’s network interface to the virtual interface of Docker’s embedded
Linux virtual machine, not to the physical interface of the host system.
