Chart for Curator

Elasticsearch Curator helps you curate, or manage, your Elasticsearch indices by:

• Obtaining the full list of indices from the cluster, as the actionable list
• Iterating through a list of user-defined filters to progressively remove indices from the actionable list as needed.

Our Chart deletes all indices prefixed with either logstash- or logsystemd older than 14 days.

Installation

From our chart repository

helm repo add cnct https://charts.cnct.io
helm repo update
helm install cnct/curator --set security.password="changeme"

To install from local repository

helm install --name my-release --namespace my-namespace ./curator --set security.password="changeme"

To install from local, overriding the base image and tag directly:

helm install --name my-release --namespace my-namespace \
  --set image.name=bobrik/curator \
  --set image.tag=5.2.0 \
  ./curator --set security.password="changeme"

To install from local, overriding with a values file:

helm install --name my-release --namespace my-namespace \
  --values ./staging-values.yaml \
  ./curator --set security.password="changeme"

In which the file ./staging-values.yaml contains:

image:
  name: bobrik/curator
  tag: 5.2.0

# sets the cron job to execute everyday at 2am
schedule: "00 2 * * *"
