kubernetes部署zabbix（k8s）

前言：部署的方式有很多中，这里我们介绍使用容器的方式部署方便日后迁移，这里我使用的是k8s部署的方式，其他方式大家自行参考https://www.zabbix.com/documentation/5.2/zh/manual/installation/containers

 

1、首先我们要准备一个mysql数据库，mysql数据放着容器里跑相对性能较差我们用虚拟机来跑，如果生产环境机器较多监控指标很多可以使用物理机配上SSD磁盘来跑mysql，zabbix性能瓶颈大部分在mysql这里。这里测试我们就直接yum一个mysql

#直接安装mariadb数据库
yum -y install mariadb-server

2、安装完mysql数据库之后我们把它加进k8s集群中调用起来会比较方便

[root@master zabbix]# cat mysqlep.yml 
apiVersion: v1
kind: Endpoints
metadata:
  name: mysql
  namespace: monitoring
  labels:
    app: zabbix-server
subsets:
  - addresses:
      - ip: 172.16.149.216
    ports:
      - port: 3306


---
apiVersion: v1
kind: Service
metadata:
  name: mysql
  namespace: monitoring
  labels:
    app: zabbix-server
spec:
  ports:
    - protocol: TCP
      port: 3306
      targetPort: 3306

3、部署zabbix-server

[root@master zabbix]# cat zabbix_server.yml 
apiVersion: v1
kind: Service
metadata:
  name: zabbix-server
  namespace: monitoring
  labels:
    app: zabbix-server

  ports:
  - name: zabbix-server
    port: 10051
    nodePort: 30051
  type: NodePort

          protocol: TCP
        resources:
          requests:
            cpu: 1000m
            memory: 1000Mi
          limits:
            cpu: 1000m
            memory: 1000Mi
      - name: zabbix-agent
        image: zabbix/zabbix-agent:latest
        imagePullPolicy: IfNotPresent
        env:
        - name: ZBX_HOSTNAME
          value: "Zabbix server"
