如何在 Cloudformation 模板中为 VPC 的 Autoscaling Group 分配 EIP [英] How to assign EIP to Autoscaling Group of VPC in Cloudformation template

问题描述

我想将我保留的弹性 IP(ec2 经典 ip)之一分配给 VPC 中的 Autoscaling 组.使用 AWS Cli 我将 ip 移到了 vpc:

I want to assign one of my reserved Elastic IP's(ec2 classic ip) to Autoscaling group in VPC. Using AWS Cli I moved ip to vpc:

$ aws ec2 move-address-to-vpc --public-ip 23.23.23.23

并在 aws concole 中看到，此 IP 已传递给 VPC.并在资源中 Cloudformation 模板中 AutoscalingGroup 的标签中分配:

And saw in aws concole, that this IP passed to VPC. And Assigned in tags of AutoscalingGroup in Cloudformation template in Resources:

"Process": {
        "Type" : "AWS::AutoScaling::AutoScalingGroup",
        "Properties": {
            "LaunchConfigurationName": {"Ref": "PreprocessorLC"},
            "LoadBalancerNames": [{"Ref": "ProcessELB"}],
            "VPCZoneIdentifier" : [{ "Fn::Join" : [",", [ { "Ref" : "PublicSubnet1"}, { "Ref" : "PublicSubnet2"} ]]}],
            "AvailabilityZones": {"Ref": "AZs"},
            "MinSize" : "1",
            "MaxSize" : "1",
            "HealthCheckGracePeriod": 300,
            "Tags" : [
                {"Key": "Name", "Value": {"Fn::Join": ["", [{"Ref": "Env"}, "-Process"]]}, "PropagateAtLaunch": true},
                {"Key": "WorkersScalingGroup", "Value": {"Fn::Join": ["", ["Offering-", {"Ref": "Env"},  "-Process-Worker"]]}, "PropagateAtLaunch": true},
                {"Key": "EIP", "Value": {"Ref": "ProcessIP"}, "PropagateAtLaunch": true},
                {"Key": "Environment", "Value": {"Ref": "Env"}, "PropagateAtLaunch": true}
            ]
        }
    }

并在参数中添加ProcessIP"的值:

And added value of "ProcessIP" in Parameters:

"ProcessIP":{
            "Description": "DEV: 23.23.23.23",
            "Type": "String",
            "Default": "23.23.23.23",
            "AllowedValues": ["23.23.23.23"]
}

它不起作用.仍然获得随机IP.如果有人能告诉我哪里错了，或者应该添加什么才能使它工作?

And it doesn't worked. Still get random IP. If someone can tell where I'm wrong or what should to add for make it work?

谢谢！

推荐答案

这里是简单的 bash 脚本:

Here is simple bash script:

#!/bin/sh
# Region in Which instance is running
EC2_REGION='us-east-1'
AWS_ACCESS_KEY='xxxxxxxxxxxx'
AWS_SECRET_ACCESS_KEY='xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'

#Instance ID captured through Instance meta data
InstanceID=`/usr/bin/curl -s http://169.254.169.254/latest/meta-data/instance-id`

#Elastic IP captured through the EIP instance tag
Elastic_IP=`/opt/aws/apitools/ec2/bin/ec2-describe-tags -O $AWS_ACCESS_KEY -W $AWS_SECRET_ACCESS_KEY --filter resource-id=$InstanceID --filter key='EIP' | cut -f5`
Allocate_ID=`/opt/aws/apitools/ec2/bin/ec2-describe-tags -O $AWS_ACCESS_KEY -W $AWS_SECRET_ACCESS_KEY --filter resource-id=$InstanceID --filter key="AllocationID" | cut -f5`

#Assigning Elastic IP to Instance
aws ec2 associate-address --instance-id $InstanceID --allocation-id $Allocate_ID
