Plugins Management

Plugins related configuration for elasticsearch

Plugins Installation

Plugins installation has been simplified using the Logging Operator. To install the plugins inside the elasticsearch, we just need to define the list of plugins inside the esPlugins section of elasticsearch CRD.

For example:-

---
apiVersion: logging.logging.opstreelabs.in/v1beta1
kind: Elasticsearch
metadata:
  name: elasticsearch
spec:
  esClusterName: "prod"
  esVersion: "7.16.0"
  esPlugins: ["repository-s3"]

Validation of plugin installation can be done using elasticsearch-plugin or curl command.

$ kubectl exec -it elasticsearch-master-0 -n ot-operators -- ./bin/elasticsearch-plugin list
...
repository-s3

$ kubectl exec -it elasticsearch-master-0 -n ot-operators -- curl http://localhost:9200/_cat/plugins
...
elasticsearch-master-1 repository-s3 7.16.0
elasticsearch-master-2 repository-s3 7.16.0
elasticsearch-master-0 repository-s3 7.16.0

Helm Configuration

Plugin installation can also be done using helm chart of elasticsearch. We just need to define the plugins list in the values file of elasticsearch helm chart.

https://github.com/OT-CONTAINER-KIT/helm-charts/blob/main/charts/elasticsearch/values.yaml#L8

$ helm upgrade elasticsearch ot-helm/elasticsearch --namespace ot-operators \
  --set esMaster.storage.storageClass=do-block-storage \
  --set esData.storage.storageClass=do-block-storage --install
