k8s部署elasticsearch

前置环境：已部署k8s集群，ip地址为 192.168.10.1~192.168.10.5，总共5台机器。

1. 创建provisioner制备器（如果已存在，则不需要）

制备器的具体部署方式，参考我之前的文章：k8s部署rabbitmq-CSDN博客

2. 编写wms-elk-data-sc.yaml配置文件

apiVersion: storage.k8s.io/v1
kind: StorageClass # 描述资源对象为SC类型
metadata:name: wms-elk-data # SC的名称，在集群范围内需要保证唯一
provisioner: wms-nfs-provisioner # 外部制备器提供者，编写为提供者的名称
parameters:archiveOnDelete: "true" # 是否存档，false表示不存档，会删除oldPath下面的数据，true表示存档，会重命名路径
reclaimPolicy: Delete # 回收策略
volumeBindingMode: Immediate # 默认为Immediate，表示创建PVC立即进行绑定

3. 导入wms-elk-data-sc.yaml配置文件

4. 查看PVC信息

$ kubectl get pvc -n wms
$ kubectl describe pvc elasticsearch-data-elasticsearch-0 -n wms

5. 编写elasticsearch.yaml配置文件

6. 在k8s页面，wms命名空间导入elasticsearch.yaml配置文件

7. 查看部署信息

8. 查看配置信息

9. 查看Pod日志信息，检查是否有报错信息

10. 访问elasticsearch页面

192.168.10.4:9200

从其他的容器，使用elasticsearch的ip，直接访问elasticsearch，可以正常访问
