Docker Logs (Beta)
Stream Docker event logs directly to Panther over HTTPS
Overview
Panther supports ingesting Docker event logs by streaming them to an HTTP Source after they are forwarded with Fluent Bit.
How to onboard Docker Events to Panther
Step 1: Create a new Docker Events log source in Panther
In the left-side navigation bar of your Panther Console, click Configure > Log Sources.
Click Create New.
Search for "Docker Events," then click its tile.
In the slide-out panel, the Transport Mechanism dropdown in the upper-right corner will be pre-populated with the HTTP option.
Click Start Setup.
Follow Panther's instructions for configuring an HTTP Source.
When setting the Stream Type for the source, we recommend choosing JSON, as it corresponds to
Format json_lines
in the Fluent Bit configuration in the next step.When setting the Auth method for the source, we recommend using Shared Secret.
After creating the HTTP source, the Panther Console will display your HTTP Source URL. Store this value in a secure location, as you will need it in the next steps.
Step 2: Configure Fluent Bit
Follow the Getting Started with Fluent Bit instructions to install Fluent Bit as a service.
Create a Fluent Bit configuration file.
See sample configuration files for Linux and macOS below under Example configuration files.
Start Fluent Bit, passing the path to your new configuration file.
You must include the path to a
parser.conf
file that contains thedocker
parser. This is included by fluent-bit by default. On Linux, it can be found at/etc/fluent-bit/parsers.conf
.Example:
fluent-bit -c fluentbit.conf -R /etc/fluent-bit/parsers.conf
Example configuration files
Configure the following in your Fluent Bit configuration file:
[INPUT]
variables:Name: Set this to
docker_events
.Parser: Set this to
docker
.
[OUTPUT]
variables:Host: Enter your Panther URL.
Example:
logs.instance-name.runpanther.net
URI: Enter the end of the HTTP Source ingest URL (generated in Step 1 of this process), starting with
/http/
.Example:
/http/cb015ee4-543c-4489-9f4b-testaa16d7a
Header: Enter the header name you created and the secret you generated while configuring your HTTP source in the Panther Console in Step 1.
[SERVICE]
flush 1
[INPUT]
name docker_events
parser docker
[OUTPUT]
name http
match *
host logs.instance.runpanther.net
port 443
URI /http/70c55034-13f1-4e08-a018-test5f2bb0a8
Header x-panther-secret {YOUR_SECRET_HERE}
Format json_lines

Docker.Events
The following defines the Docker events log schema:
schema: Docker.Events
description: Docker events to audit system-level management operations against containers, images, networks, and volumes

fields:
- name: status
description: String representing the status of this event's operation
type: string
- name: id
description: Event id
type: string
- name: from
description: Context of where the event originated
type: string
- name: Type
description: Type of object being operated on. See reference for list of object types
type: string
- name: Action
description: The action performed. Different Types have different possible actions. See reference for list of event types
type: string
- name: Actor
description: The actor performing the event. Note in the context of Docker, this is not necessarily an end user, but can be the container itself
