Deprecated AWS Lambda Function Collector

A toolchain to scan the deprecated AWS Lambda functions.

This tool aims to collect the functions which run on the deprecated runtime in the specific AWS accounts/regions according to the "Lambda runtimes" information: https://docs.aws.amazon.com/lambda/latest/dg/lambda-runtimes.html

Usage: CLI

Usage of deprecated_lambda_func_collector:
  -all-regions
        scan all lambda supported regions; this parameter take priority over the -regions
  -assume-role-arn string
        a role ARN for assume-role
  -output string
        the output format: "json", "csv", or "tsv" (default "json")
  -regions string
        target regions to scan; this value can have multiple regions as comma-separated string
  -without-future-planned-deprecation
        exclude the future planned deprecations from the result

Example:

$ AWS_PROFILE="YOUR-AWS-PROFILE" deprecated_lambda_func_collector --regions="ap-northeast-1,us-east-1"

NOTE: as the above, AWS_PROFILE is required to specify the target AWS environment.

CLI output Example:

[
  {
    "arn": "arn:aws:lambda:ap-northeast-1:123456789012:function:go-function",
    "deprecated_runtime": "go1.x",
    "deprecation_date": "Dec 31, 2023"
  },
  ...,
  {
    "arn": "arn:aws:lambda:us-east-1:123456789012:function:node14-function",
    "deprecated_runtime": "nodejs14.x",
    "deprecation_date": "Nov 27, 2023"
  }
]
