说明

参考文档https://nacos.io/docs/latest/quickstart/quick-start-kubernetes/?spm=5238cd80.5687ac34.0.0.74f0215fmrId3r
适配当前最新版本nacos server v3.1 ，实现在k8s集群部署nacos 集群。
部署可联网，可离线。
解释：因个人不喜欢helm这样类似exe双击安装的方式，所以采用yaml文件单独管理方法配置。

创建namespace

kubectl create namespace nacos

创建MySQL数据库

单独创建一个MySQL数据库，准备好MySQL的主机域名或者ip，端口号，账户，密码，提前创建一个数据库名字是nacos，编码utf8mb4，倒入mysql-schema.sql文件 ，根据个人喜好，可使用命令，也可使用navicat等工具，具体方法可直接求助AI。
可使用自己的MySQL配置部署，也可参考下述配置，
mysql.yaml配置如下，

---
apiVersion: v1

    CREATE USER IF NOT EXISTS 'root'@'%' IDENTIFIED BY 'ComplexPassword123!';
    GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' WITH GRANT OPTION;
    FLUSH PRIVILEGES;

部署MySQL

kubectl apply -f mysql.yaml -n nacos

mysql-schema.sql 可使用navicat等工具倒入到数据库。重要文件，必须创建。

修改nacos的yaml文件

nacos-k8s-v1.yaml的nacos-cm部分，mysql配置改为真实MySQL配置。
例如文中的部署结果如下，

主机名：mysql.nacos.svc.cluster.local
端口：3306
用户名：root
密码：ComplexPassword123!

如果k8s集群资源太少，就修改副本数为1。StatefulSet的replicas: 3 改为1。常规3副本足够，若想配置更多副本，需修改NACOS_SERVERS部分，追加配置更多的同格式服务名字，例如nacos-3.nacos-headless.nacos.svc.cluster.local:8848。
配置文件里的nacos.auth.token使用命令生成，可以直接用默认值，

openssl rand -base64 48

默认联网部署，离线部署时，将镜像导入本地环境，imagePullPolicy改为IfNotPresent。
容器镜像拉取问题，可参考1ms.run做配置。

nacos.yaml配置如下，

部署nacos

kubectl apply -f nacos.yaml -n nacos

查询

确认资源已启动

kubectl get all -n nacos

仅启动是不够的，应在pod日志确认启动成功

kubectl logs -n nacos pods/nacos-0
