Root Cause

AWS CodeDeploy deployment failed due to no matching instances, lifecycle hook script failures, or agent communication issues. The CodeDeploy agent must be running and the instances must match the deployment group's tag filters.

generic

Workarounds

  1. 88% success Verify CodeDeploy agent is running and instances match deployment group tags 
    SSH into the target instance and check: sudo service codedeploy-agent status. Verify EC2 instance tags match the deployment group tag filters in the CodeDeploy console. Check agent logs at /var/log/aws/codedeploy-agent/codedeploy-agent.log.
  2. 85% success Check lifecycle event logs to identify the failing hook 
    In the CodeDeploy console, click on the failed deployment and check which lifecycle event failed. Review the script output. Check /opt/codedeploy-agent/deployment-root/<deployment-group-id>/<deployment-id>/logs/scripts.log on the instance.

Dead Ends

Common approaches that don't work:

  1. Re-deploying immediately without checking the CodeDeploy agent status 85% fail

    If the agent is stopped or not installed on target instances, redeployment will fail with the same error

  2. Modifying the appspec.yml hooks without testing locally 70% fail

    Lifecycle hook scripts may have permission issues, missing dependencies, or syntax errors that only surface at deployment time
