I'm trying to build a pipeline for the standard AWS SAM HelloWorld template using Python 3.8. I'm using this template as a pipeline example. The only change I'm making to the pipeline is the Environment/Image which I'm changing from 3.6.5 to 3.8.3, like so...
CodeBuildProject:
Type: AWS::CodeBuild::Project
Properties:
Name: {{cookiecutter.project_name.lower().replace(' ', '-')}}
Description: Build project for the {{cookiecutter.project_name}}
Artifacts:
Type: CODEPIPELINE
Environment:
Type: LINUX_CONTAINER
ComputeType: BUILD_GENERAL1_SMALL
# Image: aws/codebuild/python:3.6.5 - *Commenting this out*
Image: aws/codebuild/python:3.8.3 - *Using this instead*
EnvironmentVariables:
-
Name: BUILD_OUTPUT_BUCKET
Value: !Ref BuildArtifactsBucket
Cache:
Type: S3
Location: !Sub ${BuildArtifactsBucket}/codebuild-cache
ServiceRole: !GetAtt CodeBuildServiceRole.Arn
Source:
Type: CODEPIPELINE
Tags:
-
Key: "Stack"
Value: !Ref AWS::StackName
-
Key: "Project"
Value: {{cookiecutter.project_name}}
The Problem
I'm making this change because my lambda's runtime is python3.8. If I leave the pipeline's image as aws/codebuild/python:3.6.5 I get the following error...
Traceback (most recent call last):
File "/usr/local/lib/python3.6/site-packages/aws_lambda_builders/workflow.py", line 58, in wrapper
valid_path = binary_checker.validator.validate(executable_path)
File "/usr/local/lib/python3.6/site-packages/aws_lambda_builders/workflows/python_pip/validator.py", line 45, in validate
raise MisMatchRuntimeError(language=self.language, required_runtime=self.runtime, runtime_path=runtime_path)
aws_lambda_builders.exceptions.MisMatchRuntimeError: python executable found in your path does not match runtime.
Expected version: python3.8, Found version: /usr/local/bin/python.
However, when I change the pipeline's image to aws/codebuild/python:3.8.3, I get this error in CodeBuild's Provisioning phase...
BUILD_CONTAINER_UNABLE_TO_PULL_IMAGE: Unable to pull customer's container image. CannotPullContainerError: Error response from daemon: pull access denied for aws/codebuild/python, repository does not exist or may require 'docker login': denied: requested access to the resource is denied
When I search for "codebuild BUILD_CONTAINER_UNABLE_TO_PULL_IMAGE" I find that the error comes from using a custom build image.
My Questions
- Am I correct to be changing the pipeline's image to
aws/codebuild/python:3.8.3 - Is
aws/codebuild/python:3.8.3a valid image?
Regarding #2, I found this page and, although it's a little complicated to sift through, I believe 3.8.3 is a valid image.
Any assistance in getting my pipeline running would be appreciated.
