Agreed, but for instance, I am working on a project hosted on AWS where the trigger build action is not allowed for my user. Empty commit is my only option.
To carve out minimal permissions, you have to start with nothing and repeatedly attempt to do the action in AWS console, and check CloudTrail to see what got denied. Increase role permissions, lather, rinse, repeat until it works and pray they don't update the console and break you again.
It's possible that either this process is too tedious to be worth doing, or produces a policy more complicated than they wish to use, or requires a policy that is more permissive than they wish to use.
https://pypi.org/project/access-undenied-aws/ will allow you to start with least privilege and fix specific issues.
https://github.com/iann0036/iamlive allows an admin to perform the action via CLI and capture the policy.
Access advisor can inspect how you actually use the role and give suggestions on what to remove.
A more helpful suggestion is to experiment with these tools and then find gaps in IAM actions and submit those as feature requests via your TAM.
I've also experienced the AWS console being less than stellar at fault-tolerance when acting within very restrictive, targeted IAM roles. The only solution would be an overly broad permissions grant which is not always viable. Or well, if you spend enough money you can try to beg your TAM to get it fixed, but in the meantime between "now and never", your solution would still be pushing empty commits.
- Wooof!
