Logical Elasticsearch Backup
If it hasn't been done already, the elastic
Helm repository needs
to be added to your local configuration:
# Add elastic helm repo
$ helm repo add elastic https://helm.elastic.co
Install the Elasticsearch chart from the elastic Helm repository:
$ kubectl create namespace elasticsearch
$ helm install --namespace elasticsearch elasticsearch elastic/elasticsearch \
--set antiAffinity=soft
Once Elasticsearch is installed, create an index and insert some documents in the Elasticsearch cluster by following the commands mentioned here.
To create a Blueprint resource, please run the command below:
$ kubectl --namespace kasten-io apply -f \
https://raw.githubusercontent.com/kanisterio/kanister/0.111.0/examples/elasticsearch/blueprint-v2/elasticsearch-blueprint.yaml
Note
The Elasticsearch backup example provided above serves as a blueprint template for logical backups. Please note that these examples may need to be modified for specific production environments and setups. As a result, it is highly recommended to carefully review and modify the blueprints as needed before deploying them for production use.
Alternatively, use the Blueprints page on Veeam Kasten Dashboard to create the Blueprint resource.
Once the Blueprint is created, the StatefulSets will need to be
annotated to instruct Veeam Kasten to use the Blueprint while performing
backup operations on this Elasticsearch instance. The following example
demonstrates how to annotate the Elasticsearch StatefulSet with the
elasticsearch-blueprint
.
$ kubectl annotate statefulset elasticsearch-master kanister.kasten.io/blueprint='elasticsearch-blueprint' \
--namespace=elasticsearch
Finally, use Veeam Kasten to backup and restore the application.
