Obtaining Journalbeat for Docker is as simple as issuing a
docker pull command
against the Elastic Docker registry.
However, version 8.0.0 of Journalbeat has not yet been released, so no Docker image is currently available for this version.
Running Journalbeat with the setup command will create the index pattern and load visualizations and machine learning jobs. Run this command:
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 Journalbeat. 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/journalbeat.docker.yml
One way to configure Journalbeat on Docker is to provide
journalbeat.docker.yml via a volume mount.
docker run, the volume mount can be specified like this.
Make sure you include the path to the host’s journal. The path might be
sudo docker run -d \ --name=journalbeat \ --user=root \ --volume="/var/log/journal:/var/log/journal" \ --volume="/etc/machine-id:/etc/machine-id" \ --volume="/run/systemd:/run/systemd" \ --volume="/etc/hostname:/etc/hostname:ro" \ docker.elastic.co/beats/journalbeat:8.0.0 journalbeat -e -strict.perms=false \ -E output.elasticsearch.hosts=["elasticsearch:9200"]
journalbeat.docker.yml downloaded earlier should be customized for your environment. See Configuring Journalbeat for more details. Edit the configuration file and customize it to match your environment then re-deploy your Journalbeat container.
It’s possible to embed your Journalbeat configuration in a custom image. Here is an example Dockerfile to achieve this:
FROM docker.elastic.co/beats/journalbeat:8.0.0 COPY journalbeat.yml /usr/share/journalbeat/journalbeat.yml USER root RUN chown root:journalbeat /usr/share/journalbeat/journalbeat.yml USER journalbeat
