Why do we have to restart all VPA components? Just curious

I made the script add the latest git commit as a tag, which will cause the pods to restart if a new commit is added.
But, if local changes were made without being committed, then the tag won't change, and pods won't restart

Understood. It makes sense.

There may be other ways to handle that, such as hashing all uncommitted files and adding that to the tag. After a quick google it seemed to be more effort than it's worth

I don't think that LD_FLAGS=-s ever worked:
