Zorluk: ZorAWS CodePipeline

A developer is implementing a custom build and test action in AWS CodePipeline to integrate a proprietary security scanning tool. The scanning tool runs on an on-premises worker. The developer needs to configure the custom action and set up the worker to retrieve artifacts, perform the scan, and report the results back to the pipeline. What is the correct sequence of steps to configure this custom action workflow and execute it successfully?

  1. 1Register the custom action type with AWS CodePipeline by defining the action category, provider, version, and input/output artifact constraints.
  2. 2Add the custom action to a stage in the pipeline definition, specifying the input and output artifact locations.
  3. 3The custom job worker polls AWS CodePipeline for available jobs matching the custom action's category and provider.
  4. 4The worker acknowledges the job to receive the job details, including temporary AWS credentials and the Amazon S3 location of the input artifacts.
  5. 5The worker downloads the artifacts, executes the scan, uploads the output artifacts to S3, and calls the PutJobSuccessResult API to signal completion.

Cevap

The correct sequence starts with registering the custom action type, configuring it within the pipeline, polling for jobs from the custom worker, acknowledging the job to retrieve credentials and artifact locations, and finally reporting the success result after executing the scan.
The correct sequence begins with registering the custom action type in the AWS account, followed by defining it within the pipeline structure. During execution, the custom worker polls for the job, acknowledges the job to receive the required S3 locations and temporary credentials, performs the tasks, and reports the success result back to CodePipeline.

Adım Adım Çözüm

1
Register the custom action type.
The custom action type is created and available for use in the AWS region.
Before a pipeline can reference a custom action, its schema and configuration requirements must be registered using the CLI or CloudFormation.
2
Add the custom action to the pipeline.
The pipeline configuration is updated to include the custom action in a stage.
The custom action must be declared in a stage so that CodePipeline knows when to execute it during the release process.
3
Poll for jobs from the custom worker.
The worker detects a scheduled custom action execution.
Unlike built-in actions, custom actions require an external worker to pull work requests from the CodePipeline service using PollForJobs.
4
Acknowledge the job.
The worker obtains job details, temporary security credentials, and artifact S3 locations.
The worker must notify CodePipeline that it is starting the job. The AcknowledgeJob API response provides the credentials and artifact paths.
5
Execute the task and report success.
The pipeline stage transitions to succeeded after the worker sends the PutJobSuccessResult.
The worker processes the input artifacts, uploads output artifacts to the artifact store, and updates CodePipeline with the final success status.
