aliyun-k8s_svc绑定elb

svc阿里云特殊注解

    service.beta.kubernetes.io/alibaba-cloud-loadbalancer-spec: slb.s1.small      # 申请的elb资源类型
    service.beta.kubernetes.io/alicloud-loadbalancer-address-type: intranet       # 申请的elb内外网类型(如果不显式指定，就是外网)
    service.beta.kubernetes.io/alibaba-cloud-loadbalancer-additional-resource-tags: "A=B" # 附加的阿里云资源标签
    service.beta.kubernetes.io/alibaba-cloud-loadbalancer-id: "lb-8vbblzrcxxxxxxxx"  # 绑定已有的ELB-ID
    service.beta.kubernetes.io/alibaba-cloud-loadbalancer-force-override-listeners: "true" # 是否将svc声明的spec规则强制覆盖ELB已有规则

例子

通过绑定已有的elb，避免因elb变更，导致对外服务的ip发生变动。
