ACM.92 Decreasing handbook actions to get issues deployed with CloudFormation
This can be a continuation of my collection on Automating Cybersecurity Metrics.
I’m simply penning this as a result of I’m uninterested in deleting stacks in a rolled again state. I don’t know why CloudFormation doesn’t do that for you or have higher choices to manage it. Right here’s what I did:
The primary command above does the next:
- Describe the stack
- Get the standing worth
- Added or true (|| true) to disregard errors
- Added 2>/dev/ null to not print out errors — — one thing I typically inform individuals to not do however on this case it is sensible.
The following command checks if the stack is in a ROLLBACK_COMPLETE state and deletes the stack whether it is. I’m presuming right here you waited to your rollback to finish earlier than making an attempt to redeploy a stack. 🙂
Now the issue is…the stack remains to be making an attempt to delete. We now have to attend till it will get right into a state the place we are able to proceed, or it may find yourself in a failure state of some type. The simplest factor to do might be wait till the stack will not be on this state: DELETE_IN_PROGRESS.
Since I now need to examine the standing a number of occasions, utilizing the principal of abstraction I’ve written about many occasions on this weblog, I moved the standing examine to it’s personal perform. I additionally realized that I wanted the /dev/null in a unique place to stop getting the error message when the stack doesn’t exist.
Then I find yourself with this code in my deploy stack perform:
That ought to save me just a little time no less than.
Now again to what I actually wish to be doing. Testing out our person’s means to log into an EC2 occasion with the important thing we created.
Observe for updates.
