I have been struggling with managing and keeping track of config secrets and keys. I know that keeping secrets in code is bad karma, but managing them with environment variables becomes cumbersome with multiple microservices running on multiple servers. To worsen this, add humans and access levels.

Whenever I Google, I feel like I am the only one who has this problem. Do you guys sometimes feel like this?

If you have any solutions, hacks or services that you use, please recommend.
