aws的eks（k8s）ingress+elb部署实践

news 2025/6/26 16:22:49

eks（k8s）版本1.29

ingress 版本1.10.0

负载均衡elb

1. 创建Ingress-Nginx服务

部署项目地址【点我跳转】
推荐自定义部署 可绑定acm证书什么的自己属性

这里就是aws上面Certificate Manager产品上面创建证书 导入 创建都行

对应集群版本推荐阵列
GitHub - kubernetes/ingress-nginx: Ingress-NGINX Controller for Kubernetes

ingress下载后的deploy.yaml文件

wget https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.10.0/deploy/static/provider/aws/nlb-with-tls-termination/deploy.yaml
这个下载后 有两个80 改https下面的80为443

或者直接复制下面的文件deploy.yaml详情

下面修改的地方：

1

proxy-real-ip-cidr: XXX.XXX.XXX/XX ##对应的eks vpc的地址池

这里xx我推荐改为0.0.0.0/0

别人说是eks的vpc 那段 但这个翻译字段是代理真实ip的范围【cidr我理解范围】 所有我填0

2

service.beta.kubernetes.io/aws-load-balancer-ssl-cert: acm #acm替换自己aws的证书

进入证书复制acm列

2.部署，如果中间过程有一个单独服务部署报错  ，单独拿出来执行部署就行了报错提示忘记了

kubectl apply -f deploy.yaml

查看

kubectl get all -n ingress-nginx

这里有个坑  只有一个 ingress-nginx-controller说明副本只有一个  ：只有一个节点能用

如果想多个节点， 可以多加几个副本 增加亲和性或者绑定节点等等

分别在需要的多个节点安装上 就能是 多个节点有ingress-nginx-controller 多个节点能用

特别说明elb

我有三个节点

我这里目前只用了一个节点创建ingress-nginx-controller但是elb会自动创建的目标组有三个节点

这时候找到相应的负载均衡器，找到目标组【下图的资源映射只剩一个，错误的我已经删了】 把另外两个没有ingress-nginx-controller的节点选中点击取消注册

如果三个节点都有ingress-nginx-controller 就不需要把剩余的两个节点取消注册

elb的负载均衡器 状态是活跃的 说明负载均衡器创建正常了，还是要关注资源映射和目标组的状态

创建ingress代理eks后端服务，这里是我代理eks的nginx2的服务 端口port为26004

查看ingress 命令kubectl get ingress

有host和address ports 等字段

结果浏览器
