ACM.92 Discount of guide actions to implement issues with CloudFormation
It is a continuation of my collection on automating cybersecurity metrics.
I am solely scripting this as a result of I am uninterested in deleting stacks in a reverted state. I do not know why CloudFormation does not do that for you or have higher choices to manage it. That is what I did:
The primary command above does the next:
- Describe the stack
- Get state worth
- Added o true (|| true) to disregard errors
- Added 2>/dev/null to not print errors, one thing I normally inform individuals to not do, however on this case it is sensible.
The next command checks if the stack is in a ROLLBACK_COMPLETE state and removes the stack whether it is. I assume you waited for the rollback to finish earlier than making an attempt to redeploy a stack. 🙂
Now the issue is… the stack continues to be making an attempt to clear itself. We’ve got to attend till it will get to a state the place we will proceed, or it’d find yourself in a failure state of some kind. The simplest factor might be to attend till the stack just isn’t on this state: DELETE_IN_PROGRESS.
Since I now should test the standing a number of instances, utilizing the abstraction precept I’ve written about many instances on this weblog, I moved the standing test to its personal operate. I additionally realized that I wanted /dev/null in a distinct place to keep away from getting the error message when the stack does not exist.
I then find yourself with this code in my stack deployment operate:
That ought to save me somewhat time no less than.
Now again to what I actually wish to be doing. Testing our consumer’s capability to log in to an EC2 occasion with the important thing we created.
Observe for updates.
