AWS CodeDeploy deployment failed at event ApplicationStop - aws-code-deploy

Question

I am trying to set up auto-deployment from GitHub to AWS, using EC2.
I set Role with CodeDeployServiceRole auto policy
After following the Tutorial: Use AWS CodeDeploy to Deploy an Application from GitHub, my deployment fails at the ApplicationStop event, after trying for couple of minutes with error code HEALTH_CONSTRAINT. I'm not sure how to troubleshoot the issue/where to look.

Answer 1

These are few hints of how you can navigate your way
Logs as mentioned in comments in /var/log/aws/codedeploy-agent
As AWS support recommend you can add for one time --ignore-application-stop-failures so it will skip that step in case it failed last time and see، because the application stop Lifecycle event uses the appspec file from the last successful build so if that one is corrupted somehow this step will fail in the following builds
(not recommended) you can delete the file, that CodeDeploy uses to keep track of the previous successful deployment in the following path /opt/codedeploy-agent/deployment-root/deployment-instructions/

Answer 2

Check the latest logs at /var/log/aws/codedeploy-agent
If your deployment is failing at ApplicationStop event, then most likely the issue is your EC2 instance does not have the necessary permissions to get the artifacts from S3 bucket.
Your EC2 instance must have an IAM role attached which gives it enough permissions to download the artifacts from S3 bucket
Your EC2 must be started with an IAM role. So you may have to reboot your instance after attaching the role to it.
From your configuration, looks like you have provided permissions to CodeDeploy to perform certain actions on your EC2. You may want to check if your EC2 also has the necessary permissions to download packages from S3 bucket.

Answer 3

Another reason for this error is that the CodeDeploy Service is not running on your machine. On Windows machines, Code Deploy Service terminates sometimes, and as a result, the deployment is not downloaded on the machine. Nothing appears in the logs either.
Run services.msc and check the code deploy agent service. If it is not running, start it and retry the deployment.

Answer 4

I had the same issue and solved it by solving codedeploy-agent that wasn't working on my EC2 instance.
sudo service {httpd/apache2} status
Something might have cause the agent not to run properly
Hope it will help

Answer 5

I had the same issue. You also need to make sure that your EC2 instance has code-deploy-agent installed.
Follow the below aws guide. It worked for me.
AWS guide to install code agent in linux server
Check if the codedeploy-agent is running.
sudo service codedeploy-agent status
if not running then use below command to run
sudo service codedeploy-agent start

Answer 6

If you are using aws Windows server, check the logs at :
C:\ProgramData\Amazon\CodeDeploy\log\codedeploy-agent-log.txt
AWS Docs
To check if the codedeployagent running in windows. Open powersheel command window and run these command.
powershell.exe -Command Get-Service -Name codedeployagent
Better to stop and start again.
powershell.exe -Command Stop-Service -Name codedeployagent
powershell.exe -Command Start-Service -Name codedeployagent
Or Restarting also works
powershell.exe -Command Restart-Service -Name codedeployagent
For me I had to uninstall the codedeployagent on windows by uninstalling and deleting old files of codedeploy.
Run the below command in powershell one by one to uninstall.
wmic
product where name="CodeDeploy Host Agent" call uninstall /nointeractive
exit
After this delete the codedeploy folder at this location.
C:\ProgramData/Amazon/CodeDeploy/
Now install codedeployagent on windows.
Start the codedeployagent again.
powershell.exe -Command Start-Service -Name codedeployagent
