incubator/fluentd-elasticsearch/README.md
This chart is deprecated as we move to our own repo (https://kiwigrid.github.io) which will be puplished on hub.helm.sh soon. The chart source can be found here: https://github.com/kiwigrid/helm-charts/tree/master/charts/fluentd-elasticsearch
$ helm install stable/fluentd-elasticsearch
This chart bootstraps a Fluentd daemonset on a Kubernetes cluster using the Helm package manager. It's meant to be a drop in replacement for fluentd-gcp on GKE which sends logs to Google's Stackdriver service, but can also be used in other places where logging to ElasticSearch is required. The used Docker image also contains Google's detect exceptions (for Java multiline stacktraces), Prometheus exporter, Kubernetes metadata filter & Systemd plugins.
To install the chart with the release name my-release:
$ helm install --name my-release stable/fluentd-elasticsearch
The command deploys fluentd-elasticsearch on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.
To uninstall/delete the my-release deployment:
$ helm delete my-release
The command removes all the Kubernetes components associated with the chart and deletes the release.
The following table lists the configurable parameters of the Fluentd elasticsearch chart and their default values.
