When you deploy to create resources on AWS, Cloud Formation will create a Stack and Stack will manage the process Create, Update, Delete resource with your template you created. This process can be in status IN_PROGRESS, ROLLBACK or FAIL. So, that's why we need to find the cause of these problems.


1. AWS Cloud Formation


Go to 'CloudFoundation' to see 'Stack'

  • Go to detail this stack and open the tabs like 'Resource', 'Event', 'Template'. Check 2 tabs 'Resource' and 'Event' to know the time of the 'Stuck' event.

2. AWS Cloud Trail


Go to Cloud Trail to trace log:

  • Go to the AWS service 'Cloud Trail' > menu 'Event History' then query with time of the 'Stuck' event.

  • Click into button Setting: then choose 'Error code' in order to add this column in table 'Event History'.

  • You'll see which line has an error:

  • Go into for more detail of this error. Example, we have 'errorCode' and 'errorMessage'.

  • You should filter with 'username' or 'Read only' is false for error cases.

3. AWS Cloud Watch


Cloud Watch manage a log group. This log group manages the console output of all applications running like Lambda functions.
