k8s集群部署nacos集群

1、部署 MySQL

k8s集群上部署mysql,注意storageClassName名字,生产环境上不建议用这种方式，推荐独立部署mysql

vim nacos-mysql.yaml

apiVersion: apps/v1
kind: StatefulSet
metadata:name: nacos-mysqlnamespace: nacos
spec:serviceName: nacos-mysqlreplicas: 1selector:matchLabels:app: nacos-mysqltemplate:metadata:labels:app: nacos-mysqlspec:containers:- name: mysqlimage: mysql:5.7env:- name: MYSQL_ROOT_PASSWORDvalue: "nacos@123"- name: MYSQL_DATABASEvalue: "nacos_config"ports:- containerPort: 3306volumeMounts:- name: mysql-datamountPath: /var/lib/mysqlvolumes:- name: mysql-datapersistentVolumeClaim:claimName: nacos-mysql-pvc---
apiVersion: v1
kind: Service

apiVersion: v1
kind: PersistentVolumeClaim
metadata:name: nacos-mysql-pvcnamespace: nacos
spec:accessModes:- ReadWriteOnceresources:requests:storage: 10GistorageClassName: nfs-client

2、初始化数据库
我这里用自建的mysql,不使用k8s集群部署mysql的方式
下载nacos初始化SQL

https://github.com/alibaba/nacos/blob/2.4.1/distribution/conf/mysql-schema.sql

登录MySQL创建数据库

mysql -u root -p -e "CREATE DATABASE nacos_config CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci;"

3、部署 Nacos 集群（3节点）
记得修改mysql数据库连接地址
vim nacos-cluster.yaml

root@opstest001:~/nacos# cat nacos-cluster.yaml
apiVersion: v1
kind: Namespace
metadata:name: nacos---

配置ingress,设置管理地址

root@opstest001:~/nacos# cat nacos-ingress.yaml 
apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:name: nacos-ingressnamespace: nacosannotations:nginx.ingress.kubernetes.io/rewrite-target: /nacos/$1nginx.ingress.kubernetes.io/proxy-read-timeout: "600"nginx.ingress.kubernetes.io/proxy-send-timeout: "600"nginx.ingress.kubernetes.io/proxy-body-size: "50m"
