阿里云ACK的应用服务如何暴露公网并挂载域名

背景介绍

针对部署到阿里云ACK集群的应用服务，实际业务场景可能需要我们暴露其中的服务到公网并要求通过域名访问改服务，那具体在阿里云平台上如何实现呢

配置步骤

新建ack集群是后续工作的第一前提由于篇幅有限就不在本文赘述，如下是基本准备工作：

1、将服务以NodePort方式部署在ACK中

如下图所示为部署的yaml文件

apiVersion: apps/v1
kind: Deployment
metadata:name: test-webnamespace: prod  labels:app: test-web
spec:replicas: 1selector:matchLabels:app: test-webtemplate:metadata:labels:app: test-webspec:containers:- name: test-webimage: registry-vpc.cn-shanghai.aliyuncs.com/prod-acr/test-web:${IMAGE-TAG}ports:- containerPort: 8080
#        resources:
#          limits:
#            cpu: "500m"
---
apiVersion: v1
kind: Service
metadata:name: test-webnamespace: prod labels:app: test-web
spec:selector:app: test-webports:- name: httpprotocol: TCPport: 80targetPort: 8080- name: httpsprotocol: TCPport: 443targetPort: 8080type: NodePort

2、配置AlbConfig

如下图所示，在工作负载-自定义资源中添加AlbConfig
在这里插入图片描述

apiVersion: alibabacloud.com/v1
kind: AlbConfig
metadata:name: test-prod-albannotations:kubectl.kubernetes.io/last-applied-configuration: >{"apiVersion":"alibabacloud.com/v1","kind":"AlbConfig","metadata":{"annotations":{},"name":"test-prod-alb"},"spec":{"config":{"addressType":"Internet","id":"alb-dgggggggsaaayy7","name":"test-prod-alb","zoneMappings":[{"vSwitchId":"vsw-xxxxxyyyyyyyyg"},{"vSwitchId":"vsw-xxxxxxxyyyyhib"}]},"listeners":[{"port":80,"protocol":"HTTP"},{"port":443,"protocol":"HTTPS"}]}}
spec:config:addressType: InternetforceOverride: trueid: alb-dgggggggsaaayy7listenerForceOverride: truename: test-prod-albzoneMappings:- vSwitchId: vsw-xxxxxyyyyyyyyg- vSwitchId: vsw-xxxxxxxyyyyhiblisteners:- port: 80protocol: HTTP- port: 443protocol: HTTPS

其中config.id代表是已有的ALB实例的ID，config.name则可以自定义，config.forceOverride为true则会强制替换已有的ALB实例的配置，zoneMappings.vSwitchId表示vpc网络的交换机的实例id

3、新建IngressClass

如下图所示，在工作负载-自定义资源中添加IngressClass
在这里插入图片描述

apiVersion: networking.k8s.io/v1
kind: IngressClass
metadata:name: alb
spec:controller: ingress.k8s.alibabacloud/albparameters:apiGroup: alibabacloud.comkind: AlbConfigname: test-prod-albscope: Cluster
