You can get a lot of information about site title in this url. And Elasticsearch, Kibana and Filebeat installation will explain under this topic.To do this you should follow steps below.
ELASTICSEARCH INSTALLATION
Step1:
Create new storage class on your cluster, if you dont have. This installation has been tried the which has a one worker node cluster. Then we will use the statefulset resources for installation of elasticsearch.Create new storage class on your cluster, if you dont have. This installation has been tried on the kubernetes cluster which has a one worker node cluster. Then we will use the statefulset resources for installation of elasticsearch application.
alias k=kubectlvim st-class.yamlapiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
name: local-storage
provisioner: kubernetes.io/no-provisioner
volumeBindingMode: WaitForFirstConsumerk apply -f st-class.yamlStep2:
Create folder under the your worker node to using the host path, then create persistent volume resources.
Light Info: We have been used the local storage for this installation. This storage class not supported the automatically creating pv resources. If you have another storage class like ceph and etc. you have not to create the persisten volume, because your storage class will support automaticall creating persisten volume resources. You just specify the pvc template in the statefulset yaml file that’s enough.
Run the below command under the worker node(just command of folder create)
mkdir /opt/es01 /opt/es02 /opt/es03vim es-pv.yamlapiVersion: v1
