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:8.12.2
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.
You can use the Cosign application to verify the Heartbeat Docker image signature.
wget https://artifacts.elastic.co/cosign.pub cosign verify --key cosign.pub docker.elastic.co/beats/heartbeat:8.12.2
cosign command prints the check results and the signature payload in JSON format:
Verification for docker.elastic.co/beats/heartbeat:8.12.2 -- The following checks were performed on each of these signatures: - The cosign claims were validated - Existence of the claims in the transparency log was verified offline - The signatures were verified against the specified public key
Running Heartbeat 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 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/8.12/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.
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:8.12.2 COPY --chown=root:heartbeat heartbeat.yml /usr/share/heartbeat/heartbeat.yml
Required network capabilitiesedit
Under Docker, Heartbeat 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_RAW docker.elastic.co/beats/heartbeat:8.12.2
