* [stable/elastalert] Fix verbose/confusing index names on Elasticsearch 6.x I had to set the writeback index to just `elastalert` in order to prevent elastalert to create verbose or confusing indices/types named like `elastalert_status_status/elastalert_status`, `elastalert_status_silence/elastalert_silence`, `elaststatus_status/elastalert`. The `_status` suffixes are redundant. For more context, see the elastalert issue https://github.com/Yelp/elastalert/pull/1488 which was fixed via https://github.com/Yelp/elastalert/commit/c250100b7be07c68a53789569a86f87193ec37f4 * fix(elastalert): Bump chart version
Elastalert Helm Chart
elastalert is a simple framework for alerting on anomalies, spikes, or other patterns of interest from data in Elasticsearch.
TL;DR;
For ES 5.x:
$ helm install stable/elastalert
For ES 6.x:
$ helm install stable/elastalert --set writebackIndex=elastalert
# Open Dev Tools on Kibana and send the below.
# Otherwise elastalert ends up with errors like "RequestError: TransportError(400, u'search_phase_execution_exception', u'No mapping found for [alert_time] in order to sort on')"
PUT /elastalert/_mapping/elastalert
{
"properties": {
"alert_time": {"type": "date"}
}
}
See the comment in the default values.yaml to know why writebackIndex is required for ES 6.x.
Installing the Chart
To install the chart with the release name my-release:
$ helm install --name my-release stable/elastalert
The command deploys elastalert on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.
Uninstalling the Chart
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.
