is there a way to configure external elasticsearch cluster . I have noticed flags in configuration files and tried to set up external cluster with this values.yaml flags on kubernetes
i regret to inform you that this is currently not supported the Community Edition is basically a monolith with batteries included.
If you have the need to cluster your application, the Datacenter Edition () might be something that you could look into. Still does not allow to have a external elasticsearch cluster but you could split in between highly available search and application nodes
