kubernetes 环境
- system os: macOS
- install tool: docker-desktop
- docker: 24.0.7
- kubernetes: v1.28.2
- component: ingress-nginx-controller, cert-manager, external-dns
ingress-nginx-controller
- 提供访问入口、反向代理、卸载证书...
cert-manager
- 自动颁发应用域名证书(self-signed or let's encrypt)
external-dns
- 为应用新域名添加 DNS 记录到外部 DNS 服务
应用部署流程
- 创建应用 Deployment 、Service 、Ingress 配置
- 安装应用配置
- cert-manager 签发证书
- external-dns 添加 DNS 记录
期望应用安装完，在本地能直接使用 https+域名访问应用，
以上 1 、2 、3 都没问题，第 4 步 external-dns 提示错误日志
Failed to create CNAME record named 'echo.mylabs.work' to 'localhost' with ttl 0 for Alibaba Cloud DNS: SDK.ServerError ErrorCode: SubDomainInvalid.Value Message: The DNS record is invalid or in the wrong format. 问题出在 ingress ip 分配的是 localhost

...`ingress service` status: loadBalancer: ingress: - hostname: localhost 关于 LoadBalancer 问题
- 因为不是云环境也没有部署类似 MetalLB 服务，LoadBalancer service 是如何分配 host/ip 的？
- 如果想让 LoadBalancer service 绑定本机(宿主机)局域网 ip, 应该如何做？
尝试过给 service 配置了loadBalancerIP或者externalIPs没有产生效果
