This guide will give an overview on how the KubeDB Autoscaler operator autoscales the database compute resources i.e. cpu
and memory
using elasticsearchautoscaler
crd.
KubeDB
concepts:
The Auto Scaling process consists of the following steps:
At first, a user creates a Elasticsearch
Custom Resource Object (CRO).
KubeDB
Provisioner operator watches the Elasticsearch
CRO.
When the operator finds a Elasticsearch
CRO, it creates required number of StatefulSets
and related necessary stuff like secrets, services, etc.
Then, in order to set up autoscaling of the various components of the Elasticsearch
database the user creates a ElasticsearchAutoscaler
CRO with desired configuration.
KubeDB
Autoscaler operator watches the ElasticsearchAutoscaler
CRO.
KubeDB
Autoscaler operator generates recommendation using the modified version of kubernetes official recommender for different components of the database, as specified in the ElasticsearchAutoscaler
CRO.
If the generated recommendation doesn’t match the current resources of the database, then KubeDB
Autoscaler operator creates a ElasticsearchOpsRequest
CRO to scale the database to match the recommendation generated.
KubeDB
Ops-manager operator watches the ElasticsearchOpsRequest
CRO.
Then the KubeDB
Ops-manager operator will scale the database component vertically as specified on the ElasticsearchOpsRequest
CRO.
In the next docs, we are going to show a step-by-step guide on Autoscaling of various Elasticsearch database components using ElasticsearchAutoscaler
CRD.
