local agent run failing on unknown runtime

[dougch]

Describe the bug

Our buildspecs uses runtime-version python 3.x, but the local codebuild is erroring out expecting a specific version.

To Reproduce
Steps to reproduce the behavior:

• checkout https://github.com/aws/s2n-tls/
• setup local codebuild per the docs
• run ./codebuild_build.sh -i "$IMAGE" -l amazon/aws-codebuild-local:aarch64 -a ./output -m -b codebuild/spec/buildspec_ubuntu_integ_openssl111.yml

Expected behavior

• Runs with a python 3.x environment

@dougch - Thanks for reporting the issue. Aliasing is not supported in CodeBuild local yet. Please use the specific version of the runtime when using CodeBuild local. Once we have this fixed, we'll provide an update here.

Why does this show 3.x as supported? https://docs.aws.amazon.com/codebuild/latest/userguide/runtime-versions.html

I am having this same issue with 3.8:

YAML_FILE_ERROR: Unknown runtime version named '3.8' of python. This build image has the following versions: 3.9

Not sure why it's saying the build version only has 3.9 when I have been using the same build for a while now and it worked before. (LinuxBuildImage.AMAZON_LINUX_2_3 which is shown python 3.8 to be available)

I updated to 3.9 to get this to work but this was a random issue I did not expect. Again, not sure why 3.8 worked for over a year but today it doesn't. I haven't check on deployed systems already but on a new deployment from the same package, I ran into this.
