 Modify the Build Stage to Add a Test Action with a RunOrder Value of 2:

The build stage in AWS CodePipeline can have multiple actions. By adding a test action with a runOrder value of 2, the test action will execute after the initial build action completes.

 Use AWS CodeBuild as the Action Provider to Run Unit Tests:

AWS CodeBuild is a fully managed build service that compiles source code, runs tests, and produces software packages.

Using CodeBuild to run unit tests ensures that the tests are executed in a controlled environment and that only the code changes that pass the unit tests proceed to the deploy stage.

Example configuration in CodePipeline:

{

" name " : " BuildStage " ,

" actions " : [

{

" name " : " Build " ,

" actionTypeId " : {

" category " : " Build " ,

" owner " : " AWS " ,

" provider " : " CodeBuild " ,

" version " : " 1 "

},

" runOrder " : 1

},

{

" name " : " Test " ,

" actionTypeId " : {

" category " : " Test " ,

" owner " : " AWS " ,

" provider " : " CodeBuild " ,

" version " : " 1 "

},

" runOrder " : 2

}

]

}

By integrating the unit tests into the build stage and ensuring they run after the build process, the pipeline guarantees that only code changes passing all unit tests are deployed.

AWS X-Ray provides distributed tracing, which allows visualization of latencies and errors within microservices, pinpointing bottlenecks or delays.

Instrumenting application code with the X-Ray SDK and running the X-Ray daemon as a DaemonSet in EKS ensures tracing data is collected cluster-wide.

Container Insights (Option B) provides resource-level metrics but not detailed request tracing.

CloudWatch alarms and alerts (Option C) detect symptoms but don ' t provide root cause tracing.

Increasing timeouts (Option D) only masks the issue and does not diagnose it.
