Your team is building up some microservice applications using Java.
As part of the CI/CD pipeline, AWS CodeBuild is in charge of the build phase and provides Artifacts that are stored in S3
To better manage the build commands, the team manages several buildspec files rather than directly inserts build commands when the build runs.
About the usage of buildspec files, which description is INCORRECT?
Click on the arrows to vote for the correct answer
A. B. C. D.Correct Answer - D.
AWS CodeBuild service has used buildspec files as a collection of build commands and related settings.
Its details can be found in https://docs.aws.amazon.com/codebuild/latest/userguide/build-spec-ref.html.
Option A is incorrect: By default, the buildspec file is named as buildspec.yml.
However, this file name can be overridden by other names, which can be done by AWS CLI.
Option B is incorrect: Because the buildspec file can be combined with the source code.
Option C is incorrect: Because although the buildspec file name may differ, there must be only 1 file per build project.
Option D is CORRECT: Because YAML format is the only file format supported for build spec files.
Buildspec files cannot be in JSON format per AWS latest: https://docs.aws.amazon.com/codebuild/latest/userguide/build-spec-ref.html.
Sure, I'd be happy to help explain the correct and incorrect descriptions related to the usage of buildspec files in AWS CodeBuild:
A. Users can override the default build spec file name such as buildspec_test.yml. This description is correct. When using AWS CodeBuild, the default name for the buildspec file is buildspec.yml. However, users can override this default name and provide a custom name for the buildspec file. This can be done by specifying the file name in the buildspec field of the buildspec declaration in the build project configuration, or by using the --buildspec-file option when running the build.
B. The source code can be combined along with the build spec file This description is incorrect. The buildspec file is a separate file that is used to define the build commands and settings for the build process. It does not combine or include the source code of the application being built. The source code is typically stored in a version control system such as Git, and is usually retrieved by AWS CodeBuild from the specified repository location.
C. There should be only one build spec file for a given build project. This description is incorrect. In fact, AWS CodeBuild allows for multiple buildspec files to be used within a single build project. This can be useful when you want to build and deploy different versions or branches of the application, or when you want to test different configurations of the build process. You can specify the buildspec file to use for a specific build by either using the --buildspec-file option when running the build, or by specifying the file name in the buildspec field of the buildspec declaration in the build project configuration.
D. Build spec files must be expressed in JSON format. This description is incorrect. While AWS CodeBuild does support the use of JSON-formatted buildspec files, it also supports the use of YAML-formatted buildspec files. In fact, YAML is the preferred format for buildspec files in AWS CodeBuild, as it is generally easier to read and write than JSON. When specifying the format of the buildspec file, you can use either "JSON" or "YAML" in the buildspec declaration in the build project configuration.
