Obtaining Heartbeat for Docker is as simple as issuing a
docker pull command
against the Elastic Docker registry.
docker pull docker.elastic.co/beats/heartbeat:8.3.3
Alternatively, you can download other Docker images that contain only features available under the Apache 2.0 license. To download the images, go to www.docker.elastic.co.
Running Heartbeat with the setup command will create the index pattern and load visualizations and machine learning jobs. Run this command:
docker run \ docker.elastic.co/beats/heartbeat:8.3.3 \ 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 Heartbeat. 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/8.3/deploy/docker/heartbeat.docker.yml
One way to configure Heartbeat on Docker is to provide
heartbeat.docker.yml via a volume mount.
docker run, the volume mount can be specified like this.
docker run -d \ --name=heartbeat \ --user=heartbeat \ --volume="$(pwd)/heartbeat.docker.yml:/usr/share/heartbeat/heartbeat.yml:ro" \ docker.elastic.co/beats/heartbeat:8.3.3 \ --strict.perms=false -e \ -E output.elasticsearch.hosts=["elasticsearch:9200"]
heartbeat.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 Heartbeat container.
It’s possible to embed your Heartbeat configuration in a custom image. Here is an example Dockerfile to achieve this:
FROM docker.elastic.co/beats/heartbeat:8.3.3 COPY --chown=root:heartbeat heartbeat.yml /usr/share/heartbeat/heartbeat.yml
