Elasticsearch plugin on Kubernetes

Question

I need to restart the Elasticsearch node after installing the injest-attachment plugin on Kubernetes Engine on Google Cloud Platform. I have deployed Elasticsearch on a pod. What is the best way to restart the Elasticsearch nodes?

Answer 1

If Elasticsearch is running directly on the VM:

systemctl restart elasticsearch

If Elasticsearch is running as a container on docker:

docker restart <container-id>

If Elasticsearch is running as a Kubernetes pod (deployed through a Kubernetes manifest):

• update the image tag in the manifest if needed, and do kubectl apply
• Or use kubectl replace or kubectl edit commands

On Kubernetes, ideally, you should use the declarative way of updating the manifests and then do a kubectl apply -f
