### 安装 eck ###

> 官网：https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-deploy-eck.html

安装 crds 和 operator

kubectl create -f https://download.elastic.co/downloads/eck/2.4.0/crds.yaml
    kubectl apply -f https://download.elastic.co/downloads/eck/2.4.0/custom resource definitions.yaml

查看 operator 运行日志

kubectl -n elastic-system logs -f statefulset.apps/elastic-operator

### 安装 elastic ###

部署命令

kubectl apply -f deployment.yaml

deployment.yaml 文件

apiVersion: elasticsearch.k8s.elastic.co/v1
    kind: Elasticsearch # 需要安装es operator
    metadata:
      name: es
      namespace: els-test
    spec:
      version: 7.11.2
      http:
        tls:
          selfSignedCertificate:
            disabled: true
      nodeSets:
        - name: es
          count: 3
          volumeClaimTemplates:
            - metadata:
                name: elasticsearch-data
              spec:
                accessModes:
                  - ReadWriteOnce
                resources:
                  requests:
                    storage: 10Gi
                storageClassName: nfs-client
          podTemplate:
            spec:           
              containers:
                - name: elasticsearch
                  env:
                    - name: ES_JAVA_OPTS
                      value: "-Xms2g -Xmx2g"
                  resources:
                    requests:
                      memory: 3Gi
                    limits:
                      memory: 3Gi

> namespace：配置命名空间  
> tls：关闭 tls 协议，配置文章：https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-transport-settings.html  
> storageClassName：配置存储卷，可以参考文章 [nfs-client][]  
> storage：配置存储空间，预设 10Gi，配置文章：https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-volume-claim-templates.html  
> resources：配置最大最小内存，配置文章：https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-managing-compute-resources.html  
> ES\_JAVA\_OPTS：配置最大最小 java 内存，配置文章：https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-jvm-heap-dumps.html

**部署结果**

账号：elastic  
密码：

kubectl  get secret es-es-elastic-user -n els-test -o=jsonpath='{.data.elastic}' | base64 --decode

![在这里插入图片描述][a0f4f511eeca41f3913ceacf9e8bedee.png]

配置 ingress 或 nodeport ，参考文章：[ingress 部署][ingress]

结果如下即 elastic 部署成功，cluster\_name 是 es

### 部署 Kibana ###

部署命令

kubectl apply -f kibana.yaml

kibana.yaml

apiVersion: kibana.k8s.elastic.co/v1
    kind: Kibana
    metadata:
      name: kibana
      namespace: els-test
    spec:
      version: 7.11.2
      count: 1
      elasticsearchRef:
        name: es
      http:
        tls:
          selfSignedCertificate:
            disabled: true

> namespace：和 elastic 一样  
> tls：关闭 tls 协议  
> elasticsearchRef：和 elastic 的 cluster\_name 一样  
> 编写 deployment.yaml 文件
