Fluentd is an open source data collector, which lets you unify the data collection and consumption for a better use and understanding of data.
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 |
|---|---|
| v1.x | stable |
| v0.12 | Old stable, no longer updated |
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.
If you don't setup systemd in the container, fluentd shows following messages by default configuration.
[warn]: #0 [in_systemd_bootkube] Systemd::JournalError: No such file or directory retrying in 1s
[warn]: #0 [in_systemd_kubelet] Systemd::JournalError: No such file or directory retrying in 1s
[warn]: #0 [in_systemd_docker] Systemd::JournalError: No such file or directory retrying in 1s
You can suppress these messages by setting disable to FLUENTD_SYSTEMD_CONF environment variable in your kubernetes configuration.
By historical reason, elasaticsearch image executes sed command during startup phase when FLUENT_ELASTICSEARCH_USER or FLUENT_ELASTICSEARCH_PASSWORD is specified. This sometimes causes a problem with read only mount.
To avoid this problem, set "true" to FLUENT_ELASTICSEARCH_SED_DISABLE environment variable in your kubernetes configuration.
Some images are contributed by users. If you have a problem/question for following images, ask it to contributors.

Kubernetes Logging with Fluentd
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
