Elasticsearch Chart

This chart is based on the elasticsearch/elasticsearch image.

Fluent-Bit Chart

Fluent Bit is an open source and multi-platform Log Forwarder.

This chart will do the following:

• Install a configmap for Fluent Bit
• Install a daemonset that provisions Fluent Bit [per-host architecture]

kibana

kibana is your window into the Elastic Stack. Specifically, it's an open source (Apache Licensed), browser-based analytics and search dashboard for Elasticsearch.
