本文介绍如何使用Kubernetes部署Zabbix监控系统，包括创建MySQL数据库、Zabbix Server及Zabbix Web界面的部署文件，并详细展示了各组件的配置参数与服务端口映射。

k8s部署zabbix监控系统

1.创建mysql部署文件
vim mysql-deploy.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
name: mysql
spec:
replicas: 1
selector:
matchLabels:
app: mysql
strategy:
type: Recreate
template:
metadata:
labels:
app: mysql
spec:
containers:
- image: mysql:5.7
name: mysql
imagePullPolicy: IfNotPresent
env:
- name: MYSQL_ROOT_PASSWORD
value: "zabbix"
       - name: MYSQL_DATABASE
value: "zabbix"
       - name: MYSQL_USER
value: "zabbix"
- name: MYSQL_PASSWORD
value: "zabbix"
ports:
- containerPort: 3306
name: mysql
---
apiVersion: v1
kind: Service
metadata:
name: mysql
spec:
type: NodePort
ports:
- port: 3306
nodePort: 30006
protocol: TCP
targetPort: 3306
selector:
app: mysql

2.部署zabbix-server
vim zabbix-server-deploy.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
name: zabbix-server
spec:
replicas: 1
selector:
matchLabels:
app: zabbix-server
template:
metadata:
labels:
app: zabbix-server
spec:
containers:
- name: zabbix-server
image: zabbix/zabbix-server-mysql
imagePullPolicy: IfNotPresent
ports:
- containerPort: 10051
name: server
protocol: TCP
readinessProbe:
tcpSocket:
port: server
initialDelaySeconds: 5
periodSeconds: 10
livenessProbe:
tcpSocket:
port: server
initialDelaySeconds: 15
periodSeconds: 20
env:
- name: DB_SERVER_HOST
value: "mysql"
- name: MYSQL_USER
value: "zabbix"
- name: MYSQL_PASSWORD
value: "zabbix"
- name: MYSQL_DATABASE
value: "zabbix"
- name: DB_SERVER_PORT
value: "3306"
---
apiVersion: v1
kind: Service
metadata:
name: zabbixserver
spec:
type: NodePort
ports:
- port: 10051
nodePort: 30051
protocol: TCP
targetPort: 10051
selector:
app: zabbix-server

3.部署zabbix-web
vim zabbix-web-deploy.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
name: zabbix-web
spec:
replicas: 2
selector:
matchLabels:
app: zabbix-web
template:
metadata:
labels:
app: zabbix-web
spec:
containers:
- image: zabbix/zabbix-web-nginx-mysql
name: zabbix-web
imagePullPolicy: IfNotPresent
ports:
- containerPort: 80
name: web
protocol: TCP
env:
- name: DB_SERVER_HOST
value: "mysql"
- name: ZBX_SERVER_HOST
value: "zabbixserver"
- name: MYSQL_USER
value: "zabbix"
- name: MYSQL_PASSWORD
value: "zabbix"
- name: TZ
value: "Asia/Shanghai"
---
apiVersion: v1
kind: Service
metadata:
name: zabbix-web
spec:
type: NodePort
ports:
- port: 80
protocol: TCP
nodePort: 30080
targetPort: 80
selector:
app: zabbix-web
