Kubernetes Events

Kubernetes exports it events through the API server. This input plugin allows to retrieve those events as logs and get them processed through the pipeline.

Configuration

• * As of Fluent-Bit 3.1, this plugin uses a Kubernetes watch stream instead of polling. In versions before 3.1, the interval parameters are used for reconnecting the Kubernetes watch stream.

Threading

This input always runs in its own thread.

Getting Started

Kubernetes Service Account

The Kubernetes service account used by Fluent Bit must have get, list, and watch permissions to namespaces and pods for the namespaces watched in the kube_namespace configuration parameter. If you're using the helm chart to configure Fluent Bit, this role is included.

Simple Configuration File

In the following configuration file, the input plugin kubernetes_events collects events every 5 seconds (default for interval_nsec) and exposes them through the standard output plugin on the console.

[SERVICE]
    flush           1
    log_level       info

[INPUT]
    name            kubernetes_events
    tag             k8s_events
    kube_url        https://kubernetes.default.svc

[OUTPUT]
    name            stdout
    match           *

Event Timestamp

Event timestamps are created from the first existing field, based on the following order of precedence:

1. lastTimestamp

2. firstTimestamp

3. metadata.creationTimestamp
