We can use AWS Command Line Interface (CLI) to get the ami-id. The api <code>describe-images</code> describes images that are available to you. It is found that the owner id for amazon-ecs-optimized images is <code>591542846629</code>. 

The following script returns the latest amazon-ecs-optimized image id in the region <code>ap-northeast-1</code>. 

<pre><code>name=$(aws --region ap-northeast-1 ec2 describe-images \
 --owners 591542846629| awk -F ': ' '/"Name"/ { print $2 | "sort" }' \
 | tr -d '",' | grep -v rc |tail -1)

ami_id=$(aws --region ap-northeast-1 ec2 describe-images --owners 591542846629 \
 --filters Name=name,Values="$name" \
 | awk -F ': ' '/"ImageId"/ { print $2 }' | tr -d '",')

echo $ami_id

I'm also using basic name matching in case this owner adds more image types.

Here is how it can be done using boto3

<pre><code>from operator import itemgetter
# ECS Optimized AMI to use, different per region. ID changes when an updated AMI is released.
# https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs-optimized_AMI.html
AMI_NAME = 'amzn-ami-????.??.?-amazon-ecs-optimized'

session = boto3.Session()
ec2_client = self.session.client('ec2', region_name='ca-central-1')

ecs_amis = ec2_client.describe_images(
 Filters=[
 {'Name': 'name', 'Values': [AMI_NAME, ]},
 {'Name': 'state', 'Values': ['available', ]}
 ]
)
ecs_amis = ecs_amis.get('Images')
ecs_amis = sorted(ecs_amis, key=itemgetter('CreationDate'), reverse=True)
ami_id = ecs_amis[0]['ImageId']
</code></pre>

And <code>ami_id</code> now contains the latest ami as per CreationDate. Cheers!

blocks|key|4366067|text|更安全的做法是打印出所有AMI及其元数据和日期，然后选择。AWS+CLI限制返回的AMI数量。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4366068|这是我的，它类似于上面的，但使用了一些过滤器，我还替换了一些可互换的选项。|4366069|#+Owners

It's safer to print out all of the AMIs with their metadata and dates, and then choose. AWS CLI limits how many AMIs are returned.

Here's mine, it's similar to above, but with some filters, and also I substitute a few options interchangeably.

<pre><code># Owners
owners=amazon
owners=aws-marketplace
owners=591542846629 # AMZN ECS
owners=microsoft

# AMI Regions
region=us-west-2
region=eu-central-1

# Amazon AMI - ECS
owners=591542846629
type="amazon-ecs-optimized"
aws ec2 describe-images \
 --region ${region} \
 --filters "Name=virtualization-type,Values=hvm" "Name=root-device-type,Values=ebs" \
 --owners "${owners}" | jq -r '.Images[] | "\(.CreationDate) \(.Name) \(.ImageId)"' | grep "${type}" | sort -r | head
</code></pre>

This can now be done via the SSM Parameter Store API

I ran into a requirement where I need get the EC2 ami id of the latest amazon-ecs-optimized image of a specific region. Is there any script or api that is available to pick the ami-id, that they provide while creating a new cluster?

<a href="https://i.stack.imgur.com/UcUZh.png" rel="noreferrer"><img src="https://i.stack.imgur.com/UcUZh.png" alt="Create Cluster page in AWS Console"></a>

So that once they update the console with the latest ami, I need not update my scripts.

Script or api to provide the ami-id of the latest amazon-ecs-optimized image

我遇到了一个需求，我需要获得特定区域的最新amazon-ecs优化镜像的EC2 ami id。是否有任何脚本或api可用于挑选他们在创建新集群时提供的ami-id？​​这样一旦他们用最新的ami更新了控制台，我就不需要更新我的脚本了。
