Changes from upstream
ECK
- Operator mapped to controller nodes
ES
-
SSL disabled ( Todo: provide cluster certs and setup Kibana/Fluentd to use https incl. client certs )
-
Installed Plugins:
- repository-s3
- elasticsearch-prometheus-exporter
-
Cross AZ Zone awareness is implemented via nodeSets
Kibana
- increased timeout to ES to 3 minutes
FluentD
Fluent-bit
- support for dedot Lua filter to replace "." with "_" for all annotations and labels
- support for api audit log
Manual tasks ATM
- install index template
- setup Kibana
- create
logstash-*
