Answer 3

Artifacts are files or data passed between stages in a pipeline.
Two types:
Input Artifacts: Consumed by a stage.
Output Artifacts: Produced by a stage for downstream stages.
Stored in an Amazon S3 bucket configured for the pipeline.
Format: ZIP files (compressed) containing code, build output, or deployment configurations.
Security: S3 bucket is encrypted and managed by AWS CodePipeline..

Question 4

What are stages in AWS CodePipeline?

Answer 4

Stages represent distinct phases in the pipeline (e.g., source, build, deploy).
Common stages:
Source: Fetches source code from repositories like GitHub, CodeCommit, or S3.
Build: Uses tools like CodeBuild to compile and test the code.
Deploy: Deploys to services like Elastic Beanstalk, ECS, or Lambda.
Approval (optional): Manual or automated approval gates.
Each stage consists of actions that define specific tasks.
Stages are sequential but can include parallel action

Question 5

What are common issues in AWS CodePipeline and their causes?

Answer 5

Pipeline Stuck:

Cause: Action failing or waiting for a manual approval.
Solution: Check the status of actions and logs for errors.
Artifact Issues:

Cause: Missing or incorrect artifact configurations.
Solution: Verify artifact names and ensure correct S3 bucket permissions.
Permissions Errors:

Cause: IAM roles lacking required permissions.
Solution: Review IAM policies for CodePipeline, CodeBuild, and S3.
Source Stage Fails:

Cause: Incorrect repository or branch configuration.
Solution: Confirm repository details and source provider connection.
Deployment Fails:

Cause: Issues with destination service (e.g., ECS, Lambda).
Solution: Check deployment logs and ensure proper service configuration.
