As using any elastic software you're presumably read and agree with following license
Followed yaml manifests bootstrap Elasticsearch & Kibana on Kubernetes with Elastic Cloud on Kubernetes, or Elastic and Kibana operator on top of K8s in short.
This repository was used as a starting point: cloud-on-k8s
With following specific details:
- SSD class storage of Yandex Managed Kubernetes service for persisting Elasticsearch data, sized for 300Gb each.
- Using 5 nodes with master data ingest roles
- Configured resource limits and request with tuned java options to utilize 6GB memory. Read this article for configure suitable resource usage for your cluster.
- name: elasticsearch
resources:
limits:
memory: 8Gi
cpu: 4
request:
memory: 10Gi
cpu: 8
env:
- name: ES_JAVA_OPTS
value: "-Xms6g -Xmx6g"
If you want to dedicate nodes that would run elasticsearch write ID of your kubernetes IG. Otherwise delete following:
nodeSelector:
yandex.cloud/node-group-id: <dedicated-ig-for-elasticsearch>
For more detail on configuring operator, you may refer to this docs
kubectl apply -f 01_elasticsearch_operator.yaml
kubectl apply -f 02_elasticsearch_resource.yaml
kubectl apply -f 04_elasticsearch_operator_kibana.yaml
For allowing logs from Kubernetes running application to be collected and stored in Elasticsearch we need to deploy filebeat/fluentd/logstash.
Due to mechanics how Elastic operator works, Elasticsearch is exposed via usual 9200
port, but applying tls encryption and also have random generated password. In example below we utilize Filebeat, but you could use any other solutions for your convinience. In order to properly configure Filebeat, we need to get password and CA certificate.
kubectl get secret es-log-es-http-certs-public -o json --namespace=elastic-system | jq '.metadata.namespace = "kube-system"' | jq 'del(.metadata.creationTimestamp,.metadata.ownerReferences,.metadata.resourceVersion,.metadata.selfLink,.metadata.uid)' | kubectl --namespace=kube-system apply -f -
elasticpassword="$(kubectl --namespace=elastic-system get secret es-log-es-elastic-user -o go-template='{{.data.elastic | base64decode }}')" && sed -i.bak "s/passwwwwordanchor/${elasticpassword}/g" 03_filebeat.yaml
kubectl apply -f 03_filebeat.yaml
Rally was used for meter performance of 5 nodes cluster with NVME class disks for data with same resource limitation and same Java settings at 8 vCPU 100% with 24 GB RAM and system disk on network HDD
, enabled tls, and esrally run from very same Kubernetes cluster.
esrally --track=http_logs \
--target-hosts=es-log-es-http.elastic-system.svc.cluster.local:9200 \
--pipeline=benchmark-only \
--client-options="use_ssl:true,verify_certs:true,ca_certs:'/tmp/ca.pem',basic_auth_user:'elastic',basic_auth_password:changeme"
