What is Fluentd?

Fluentd Logo

Fluentd is an open source data collector, which lets you unify the data collection and consumption for a better use and understanding of data.

Image versions

The following repository expose images based on Alpine Linux and Debian. For production environments we strongly suggest to use Debian images.

Fluentd versioning is as follows:

Series Description
v0.12 Old stable, production ready
v1.x stable

Settings

Run as root

In Kubernetes and default setting, fluentd needs root permission to read logs in /var/log and write pos_file to /var/log. To avoid permission error, you need to set FLUENT_UID environment variable to 0 in your Kubernetes configuration.

Kubernetes Logging with Fluentd

Running on OpenShift

This daemonset setting mounts /var/log as service account fluentd so you need to run containers as privileged container. Here is command example:

oc project kube-system
oc create -f https://raw.githubusercontent.com/fluent/fluentd-kubernetes-daemonset/master/fluentd-daemonset-elasticsearch-rbac.yaml
oc adm policy add-scc-to-user privileged -z fluentd
oc patch ds fluentd -p "spec:
  template:
    spec:
      containers:
      - name: fluentd
        securityContext:
          privileged: true"
oc delete pod -l k8s-app = fluentd-logging
