Create ec2 copies a.k.a ami by shell script

 

Code Sample

#!/bin/bash

InstanceID=("i-xxxxxxxxx" "i-xxxxxxxxxxxxxxxxxxx" "i-xxxxxxxxxxxx65")
ImageName="create-ami"
CurrentTime=`date +%Y%m%d`
ImageVersion=${2:-v1.1.1}
ImageDescription="create-ami-by-script"
num=1


for value in "${InstanceID[@]}";
do
            aws ec2 create-image \
                         --instance-id $InstanceID \
                          --name $ImageName-$CurrentTime-$ImageVersion-$value-$num \
                           --description "$ImageDescription" \
           --tag-specifications 'ResourceType=image,Tags=[{Key=Name,Value=create-ami}]' \
                            'ResourceType=snapshot,Tags=[{Key=Name,Value=create-ami}]' \
                --region ap-northeast-2 --debug --profile awsprofile
                			((num+=1))
                            echo $value
done

 

To get each ec2 instance ID with aws cli for comfort,

below is the sample code to implement.

 

$ aws ec2 describe-instances \
 --profile awsprofile \
 --query 'Reservations[*].Instances[*].{Instance:InstanceId,Subnet:SubnetId}' \
 --output text --region ap-northeast-2

 

adding below option will prevent inaccurate order of ami creation since the reboot will take some time to operate for each target server.

--no-reboot
