【快速入门】2.203-快速入门-购买固定IP并绑定到主机 · Terraform阿里云实践秘籍

## 创建EIP ## 1. ECS公网IP 与eip 区别序号 |功能| ECS公网IP | EIP :-: | :-: | :-: | :-: 1 |支持的网络环境 |专有网络 |专有网络经典网络 2|是否能够单独持有|否|是 3|是否支持在ECS上的弹性插拔|否|是 4|ECS实例网卡上是否能看到该IP|经典网络：能看到；专有网络VPC：看不到|多EIP网卡可见模式下可见 2. 创建Eip EIP是一种NAT IP。它实际位于阿里云的公网网关上，通过NAT方式映射到了被绑定的云资源上。和云资源绑定后，云资源可以通过EIP与公网通信。 ● 可独立持有的公网IP ● 可用于VPC中的 ECS实例、NAT网关、私网负载均衡SLB等产品 ● 可动态绑定和解绑 ● 可自带IP地址上云，系统架构变动小，IP品牌信誉不变 ``` resource "alicloud_eip" "eip" { bandwidth = "10" # Internet charge type of the EIP, Valid values are PayByBandwidth, PayByTraffic. Default to PayByBandwidth. From version 1.7.1, default to PayByTraffic. It is only PayByBandwidth when instance_charge_type is PrePaid internet_charge_type = "PayByTraffic" # Elastic IP instance charge type. Valid values are "PrePaid" and "PostPaid". Default to "PostPaid". instance_charge_type = "PostPaid" } resource "alicloud_eip_association" "eip_asso" { allocation_id = alicloud_eip.eip.id instance_id = alicloud_instance.server.id } ``` 出现执行错误的问题,这是因为eip之前服务器已经有了ip了 ``` Error: [ERROR] terraform-provider-alicloud/alicloud/resource_alicloud_eip_association.go:99: Resource alicloud_eip_association AssociateEipAddress Failed!!!
