Docker image for the Packetbeat agent

Packetbeat is an open source application monitoring and performance management (APM) system. See for details.

This runs the Packetbeat agent inside it's own container, but by mounting the network host it is able to see the traffic from the other containers or from the applications running on the hosts.

How to use

To build:

 docker build -t packetbeat-agent .

To run:

 docker run --net=host -d packetbeat-agent packetbeat -e -c /etc/packetbeat/packetbeat.conf

The --net=host part makes it possible to sniff the traffic from other containers.

From docker hub

You can also pull the image from Docker Hub and run it like this:

docker pull packetbeat/packetbeat-agent
docker run --net=host -t -i packetbeat/packetbeat-agent packetbeat -e -c /etc/packetbeat/packetbeat.conf

But note that you will need to provide your own packetbeat.conf.
