Which of the following actions should be taken to troubleshoot this issue?
Check that an Amazon EventBridge rule has been created for the main branch to trigger the pipeline.
Check that the CodePipeline service role has permission to access the CodeCommit repository.
Check that the developer’s IAM role has permission to push to the CodeCommit repository.
Check to see if the pipeline failed to start because of CodeCommit errors in Amazon CloudWatch Logs.
Explanations:
An Amazon EventBridge rule is necessary to listen for changes in the CodeCommit repository. If the rule is not set up correctly for the main branch, the pipeline will not trigger upon code changes.
While the CodePipeline service role does need permissions to access CodeCommit, this is not the primary reason for the pipeline not triggering immediately after a push. The trigger mechanism needs to be verified first.
The developer’s IAM role permissions are relevant for pushing code to the repository, but they do not affect whether the pipeline triggers after a successful push. If the push was successful, the developer’s permissions are likely correct.
If the pipeline fails to start, it is generally logged in CloudWatch. However, if there are no triggers set up, there would be no logs to indicate a failure, making this option less relevant for the initial troubleshooting.
In my opinion, the answer is:
Check that an Amazon EventBridge rule has been created for the main branch to trigger the pipeline.
As I see it, the answer is:
Check that an Amazon EventBridge rule has been created for the main branch to trigger the pipeline.
