Overcoming the issue when AWS overwrites your KMS Position with a nonsense worth
I’ve been engaged on this automation collection and written about numerous points with KMS that I hope AWS will repair. One is the truth that they overwrite your Key Coverage Roles with a nonsense worth for those who delete or change a job.
It is a large downside for a number of causes:
- CloudFormation doesn’t acknowledge that your template and stack are old-fashioned and gained’t replace to the right position.
- You may be utterly locked out of administering the important thing if the administrator position will get deleted.
- You possibly can an unhelpful error: “Entry to KMS is Not Allowed” when making an attempt to carry out CloudFormation updates on any stacks that use that Key. That isn’t correct as a result of the IAM coverage does permit entry to KMS. The issue is that the important thing coverage doesn’t have that position in it anymore. Because you see no different errors in your stack then it’s not instantly clear what the issue is.
In an effort to repair this downside with numerous coordinated templates I deploy collectively for my newest weblog collection, I discovered that if I alter an arbitrary output parameter created solely to drive an replace then I can get key to redeploy despite the fact that nothing else has modified. The important thing coverage references one other CloudFormation stack output and so the template itself doesn’t change even when the opposite output adjustments.
I created a parameter to cross in a timestamp:
I output the timestamp to drive CloudFormation to replace:
Since AWS CloudFormation isn’t dealing with areas accurately in the meanwhile I stripped the areas out of my timestamp and put quotes round it.
This isn’t answer as a result of I’m doubtlessly paying for extra executions than I really want. AWS ought to actually not be altering Key Insurance policies on prospects. Maybe they are often disabled till up to date and stuck or warn the client in some way however don’t change buyer insurance policies. AWS usually doesn’t contact buyer information so that is very unusual.
If you wish to learn extra about automated KMS creation and KMS insurance policies take a look at this weblog submit collection and the associated code on GitHub.
