Connecting to Elasticsearch

​

Subscription Features

For Elasticsearch 7.0 or later: Formerly referred to as X-pack features, your Elastic Stack subscription will determine the features available in your Deploy Elasticsearch Database. By default, you will have the “Basic” features. If you purchase a license from Elastic, you may update your license at any time.

​

Plugins

Some Elasticsearch plugins may be installed by request. Contact Aptible Support if you need a particular plugin.

​

Configuration

Elasticsearch Databases can be configured with Elasticsearch’s Cluster Update Settings API. Changes made to persistent settings will persist across Database restarts.

Deploy will automatically set the JVM heap size to 50% of the container’s memory allocation, per Elastic’s recommendation.

​

Kibana

For Elasticsearch 7.0 or later, you can easily deploy Elastic’s official Kibana image as an App on Aptible.

​

Log Rotation

For Elasticsearch 7.0 or later: if you’re using Elasticsearch to hold log data, you may need to periodically create new log indexes. By default, Logstash and our Log Drains will create new indexes daily. As the indexes accumulate, they will require more disk space and more RAM. Elasticsearch allocates RAM on a per-index basis, and letting your logs retention grow unchecked will likely lead to fatal issues when the Database runs out of RAM or disk space.

To avoid this, we recommend using a combination of Elasticsearch’s native features to ensure you don’t accumulate too many open indexes:

• Index Lifecycle Management can be configured to delete indexes over a certain age
• Snapshot Lifecycle Management can be configured to back up indexes on a schedule, for example, to S3
• The Elasticsearch S3 Repository Plugin, which is installed by default

​

• For all Elasticsearch versions 6.8 and earlier: SSLv3, TLSv1.0, TLSv1.1, TLSv1.2
