Since the state of your system is written in code, you derive some benefits from that fact. Features such as easier auditing, code reviews, and version control are now applicable not just to the application code. The consequence is that in case anything goes wrong, reverting back to a working state requires a single git revert command.
You can use the power of Git's signed commits and SSH and GPG keys to give control over different environments. By adding a gating mechanism that makes sure only the commits meeting required standards can be pushed to the repository, you also eliminate many accidental errors that may result from running commands manually using ssh or kubectl.
