k8s部署elk+filebeat+kafka-kraft模式集群（一）ES集群+kibana部署

前言：

这次是在部署后很久才想起来整理了下文档，如有遗漏见谅，期间也遇到过很多坑有些目前还没头绪希望有大佬让我学习下

一、环境准备

1、k8s各节点部署nfs

挂载目录为 /home/k8s/elasticsearch/storage

2、安装制备器Provisioner

# cat rbac.yaml

apiVersion: v1
kind: ServiceAccount
metadata:
  name: nfs-client-provisioner
  namespace: default
---
kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: nfs-client-provisioner-runner
rules:
  - apiGroups: [""]
    resources: ["persistentvolumes"]
    verbs: ["get", "list", "watch", "create", "delete"]
  - apiGroups: [""]
    resources: ["persistentvolumeclaims"]
    verbs: ["get", "list", "watch", "update"]
  - apiGroups: ["storage.k8s.io"]
    resources: ["storageclasses"]
    verbs: ["get", "list", "watch"]
  - apiGroups: [""]
    resources: ["events"]
    verbs: ["create", "update", "patch"]
---
kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: run-nfs-client-provisioner
subjects:
  - kind: ServiceAccount
    name: nfs-client-provisioner
    namespace: default
roleRef:
  kind: ClusterRole
  name: nfs-client-provisioner-runner
  apiGroup: rbac.authorization.k8s.io
---
kind: Role
apiVersion: rbac.authorization.k8s.io/v1
metadata:

    namespace: default
roleRef:
  kind: Role
  name: leader-locking-nfs-client-provisioner
  apiGroup: rbac.authorization.k8s.io

# cat deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nfs-client-provisioner
  labels:
    app: nfs-client-provisioner

        - name: nfs-client-provisioner
          image: 3.127.33.174:8443/kubernetes/nfs-client-provisioner:latest
          volumeMounts:
            - name: nfs-client-root
              mountPath: /persistentvolumes
          env:

          nfs:
            server: 3.127.10.95
            path: /home/k8s/elasticsearch/storage

# cat es-storageclass.yaml

apiVersion: storage.k8s.io/v1

    protocol: TCP
    targetPort: 9200
  - name: cluster-port
    port: 9300
    protocol: TCP
    targetPort: 9300

        securityContext:
          privileged: true
        volumeMounts:

 kubectl get pods -n elk -o wide

 至此es集群正常部署完毕
