For a deployment using AWS Code Deploy, what is the run order of the hooks for in-place deployments?
In the context of AWS CodeDeploy for in-place deployments, the hooks execute in a specific sequence to ensure a smooth and reliable deployment process. The correct order is: ApplicationStop -> BeforeInstall -> AfterInstall -> ApplicationStart. This sequence makes certain that any running instances are stopped, the new application version is correctly installed, and then the necessary services are restarted. This ensures a seamless transition to the updated application. Thus, the correct order of hooks for in-place deployments is as follows: ApplicationStop -> BeforeInstall -> AfterInstall -> ApplicationStart.
It's B. Check the image in the link. https://docs.aws.amazon.com/codedeploy/latest/userguide/reference-appspec-file-structure-hooks.html#appspec-hooks-server
Answer A For InPlace deployment
You guys should read the questions carefully. Answer is A. You are confusing the run order of hooks for in-place deployments with the run order of hooks for blue/green deployments. For blue/green deployments, the run order of the hooks is indeed ApplicationStop -> BeforeInstall -> AfterInstall -> ApplicationStart, which matches option B. However, for in-place deployments, the correct run order of the hooks is BeforeInstall -> ApplicationStop -> AfterInstall -> ApplicationStart, as stated in option A.
From the below link: https://docs.aws.amazon.com/codedeploy/latest/userguide/reference-appspec-file-structure-hooks.html#appspec-hooks-server Neither type of deployment follows this order. BeforeInstall -> ApplicationStop -> AfterInstall -> ApplicationStart
BeforeInstall runs after ApplicationStop for ALL deployments types. The correct answer is B
Stopped -> Installed -> Started -> Validated Go with B.
B In AWS CodeDeploy for in-place deployments, the hooks run in the following order: ApplicationStop: Executed before the new application revision is downloaded. DownloadBundle: The new application revision is downloaded. BeforeInstall: Executed after the new revision is downloaded but before the new version is installed. Install: The application revision specified in the deployment is installed. AfterInstall: Executed after the application revision is installed. ApplicationStart: Invoked to start any services that were stopped during ApplicationStop. ValidateService: Ensures the service is operating correctly after the new deployment. This sequence ensures a smooth deployment process by systematically stopping, updating, and restarting the application.
I'll go with B based on the link provided by others
Ans: A For an in-place deployment using AWS CodeDeploy, the run order of the hooks is option A, "BeforeInstall -> ApplicationStop -> ApplicationStart -> AfterInstall." This is the correct order of hooks for an in-place deployment, where the deployment package is installed on the same set of Amazon EC2 instances that are running the current version of the application.

Application must be stopped before installation. Otherwise the installation may corrupt the running application’s files and cause damages. Not good.
Answer is B. There is no doubt - please go to the URL https://docs.aws.amazon.com/codedeploy/latest/userguide/reference-appspec-file-structure-hooks.html and search with "In-place deployments" In fact none of the deployments follow the order mentioned in A
Definitely, B: the order is the same in case of InPlace and Blue/Green deployment: https://docs.aws.amazon.com/codedeploy/latest/userguide/reference-appspec-file-structure-hooks.html#reference-appspec-file-structure-hooks-availability

For in-place deployment B is correct. https://docs.aws.amazon.com/codedeploy/latest/userguide/reference-appspec-file-structure-hooks.html
Application start is after install
I's B as per doc https://docs.aws.amazon.com/codedeploy/latest/userguide/reference-appspec-file-structure-hooks.html#appspec-hooks-server:~:text=a%20load%20balancer.-,Lifecycle%20event%20hook%20availability,-The%20following%20table
ApplicationStop -> BeforeInstall -> AfterInstall -> ApplicationStart -> ValidateService. Ref: https://docs.aws.amazon.com/codedeploy/latest/userguide/reference-appspec-file-structure-hooks.html
B is the correct answer.
