Exam AWS Certified Developer Associate topic 1 question 94 discussion

B) Eliminated - The finally block runs regardless of whether the build succeeds or fails. Since the requirement is to push the image only upon successful builds, this approach is unsuitable.

Add a post_build phase to the buildspec file that uses the commands block to push the Docker image.

https://docs.aws.amazon.com/codebuild/latest/userguide/build-spec-ref.html phases/*/finally Optional block. Commands specified in a finally block are run after commands in the commands block. The commands in a finally block are run even if a command in the commands block fails. For example, if the commands block contains three commands and the first fails, CodeBuild skips the remaining two commands and runs any commands in the finally block. The phase is successful when all commands in the commands and the finally blocks run successfully. If any command in a phase fails, the phase fails.

A is the correct answer, we can add command line instructions in the post_build hook in order to push the image in the repository

Its A - here is the sampel AWS code showing exactly option A : https://docs.aws.amazon.com/codebuild/latest/userguide/sample-docker.html

A - https://docs.aws.amazon.com/codebuild/latest/userguide/sample-docker.html

B is also good as in finally block you can test CODEBUILD_BUILD_SUCCEEDING to make decision.

A is the answer

A is correct

A is the answer

I think it's A

A because "phases/post_build Optional sequence. Represents the commands, if any, that CodeBuild runs after the build. For example, you might use Maven to package the build artifacts into a JAR or WAR file, or you might push a Docker image into Amazon ECR. Then you might send a build notification through Amazon SNS." https://docs.aws.amazon.com/codebuild/latest/userguide/build-spec-ref.html

I think it should be A: https://docs.aws.amazon.com/codebuild/latest/userguide/sample-docker.html#sample-docker-files In the examples, it's in the commands of post_build
