Lambda End-of-life Runtime

Level: Error

Initial version: 0.1.7

cfn-lint: E2531

tflint: aws_lambda_function_eol_runtime

Managed Lambda runtimes for .zip file archives are built around a combination of operating system, programming language, and software libraries that are subject to maintenance and security updates. When security updates are no longer available for a component of a runtime, Lambda deprecates the runtime.

Info

This rule is implemented natively in cfn-lint as rule number E2531.
