华为云CCE集群创建loadBalancer

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:metadata:name: nginx-svcnamespace: defaultuid: 9255776c-5505-4f6c-9bf3-06ff4bcba11cresourceVersion: '22021'creationTimestamp: '2024-09-01T15:38:28Z'labels:app: nginxversion: v1annotations:kubernetes.io/elb.acl-id: ''kubernetes.io/elb.autocreate: '{"name":"nginx-elb","type":"public","bandwidth_name":"cce-bandwidth-1725204558134","bandwidth_chargemode":"traffic","bandwidth_size":5,"bandwidth_sharetype":"PER","eip_type":"5_bgp","available_zone":["cn-south-2b","cn-south-1c","cn-south-1e"],"elb_virsubnet_ids":["2d1628a0-bf60-434f-938b-ae329ab43834"],"l7_flavor_name":"L7_flavor.elb.pro.max","l4_flavor_name":"","vip_subnet_cidr_id":"6d225e5c-6ee6-4bf3-b5aa-dd74e366239f"}'kubernetes.io/elb.cert-id: 1dafe21b9ec74b32a96e942fc439ae8ckubernetes.io/elb.class: performancekubernetes.io/elb.client-ca-cert-id: ''kubernetes.io/elb.eip-id: 68e2dd0c-b625-44da-94d3-91597484bb8akubernetes.io/elb.health-check-flag: 'on'kubernetes.io/elb.health-check-option: '{"protocol":"TCP","delay":"5","timeout":"10","max_retries":"3"}'kubernetes.io/elb.id: 76d56aaa-7f20-40c9-9414-0a2eea979f31kubernetes.io/elb.lb-algorithm: ROUND_ROBINkubernetes.io/elb.mark: '0'kubernetes.io/elb.protocol-port: https:443kubernetes.io/elb.security-policy-id: ''kubernetes.io/elb.security-pool-protocol: 'off'kubernetes.io/elb.tls-certificate-ids: 1dafe21b9ec74b32a96e942fc439ae8ckubernetes.io/elb.tls-ciphers-policy: tls-1-2finalizers:- service.kubernetes.io/load-balancer-cleanupmanagedFields:- manager: cfe-apiserveroperation: UpdateapiVersion: v1time: '2024-09-01T15:38:28Z'fieldsType: FieldsV1fieldsV1:f:metadata:f:annotations:.: {}f:kubernetes.io/elb.acl-id: {}f:kubernetes.io/elb.autocreate: {}f:kubernetes.io/elb.cert-id: {}f:kubernetes.io/elb.class: {}f:kubernetes.io/elb.client-ca-cert-id: {}f:kubernetes.io/elb.health-check-flag: {}f:kubernetes.io/elb.health-check-option: {}f:kubernetes.io/elb.lb-algorithm: {}f:kubernetes.io/elb.protocol-port: {}f:kubernetes.io/elb.security-policy-id: {}f:kubernetes.io/elb.security-pool-protocol: {}f:kubernetes.io/elb.tls-certificate-ids: {}f:kubernetes.io/elb.tls-ciphers-policy: {}f:labels:.: {}f:app: {}f:version: {}f:spec:f:allocateLoadBalancerNodePorts: {}f:externalTrafficPolicy: {}f:internalTrafficPolicy: {}f:ports:.: {}k:{"port":443,"protocol":"TCP"}:.: {}f:name: {}f:port: {}f:protocol: {}f:targetPort: {}f:selector: {}f:sessionAffinity: {}f:type: {}- manager: huawei-cloud-controller-manageroperation: UpdateapiVersion: v1time: '2024-09-01T15:38:37Z'fieldsType: FieldsV1fieldsV1:f:metadata:f:finalizers:.: {}v:"service.kubernetes.io/load-balancer-cleanup": {}f:status:f:loadBalancer:f:ingress: {}subresource: status- manager: huawei-cloud-controller-manageroperation: UpdateapiVersion: v1time: '2024-09-01T15:39:43Z'fieldsType: FieldsV1fieldsV1:f:metadata:f:annotations:f:kubernetes.io/elb.eip-id: {}f:kubernetes.io/elb.id: {}f:kubernetes.io/elb.mark: {}f:spec:f:loadBalancerIP: {}

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）
