Listing of AWS Lambda Python 2.7 functions that will be EOL(across all regions)

#aws #lambda #python #shell

The official AWS blog posted An announcement titled Announcing end of support for Python 2.7 in AWS Lambda.

In the post, there is an AWS CLI command that lists Python 2.7 Lambda functions.

aws lambda list-functions --function-version ALL --output text --query "Functions[?Runtime=='python2.7'].FunctionArn"

Across all regions

Here is a shell to run its command across all regions.

Script(list-py27functions.sh)

for region in `aws ec2 describe-regions --query "Regions[].RegionName" --region us-west-1 --output text`
do
    echo "[${region}]"
    aws lambda list-functions --region ${region} --output text --query "Functions[?Runtime=='python2.7'].{ARN:FunctionArn, Runtime:Runtime}"
done
echo "finished"

Usage

export AWS_PROFILE=xxxx # Not necessary if you always set the default profile.
sh list-py27functions.sh

Output

[eu-north-1]
[ap-south-1]
[eu-west-3]
[eu-west-2]
[eu-west-1]
[ap-northeast-3]
[ap-northeast-2]

You can also run it from within CloudShell without specifying a profile.
