华为云CCE集群创建loadBalancer

news2024/9/22 21:30:07

一、目的

二、创建应用

三、创建服务 loadBalancer

四、域名解析

五、验证

一、目的

1、为CCE容器应用创建loadBalancer服务，并且绑定https协议的域名

2、公网访问域名: https://test.******.com

3、CCE创建用于公网域名访问的loadBalancer，不需要额外创建ingress路由

二、创建应用

1、创建无状态应用: nginx

2、创建无状态应用nginx的清单内容

# 命令行创建无状态 nginx 应用代码:

kubectl create deploy nginx --image=nginx:alpine-perl -n default

三、创建服务 loadBalancer

1、创建应用nginx的服务

2、注意：上面设置关于设置域名的内容是需要提前在ELB导入域名证书

3、nginx服务清单文件

第1步创建loadBalancer服务的代码结果是：

# 创建 loadblance 的代码结果 nginx-svc.yaml 是:

4、负载均衡器ELB

loadblance服务创建成功后，自动成名为 nginx-elb 的负载均衡（默认是受保护，不建议手工直接修改改的）
