(Writing in with a story/telling of what happened, not a suggestion!) I joined a company where we used Slack to bother teammates, as we went around setting up dozens and dozens and dozens and dozens of microservices. Pretty poor consistency across variable names. People unsure what changes they'd made locally. It was a mess. I was setting everything up for myself via Ansible. So I'd try to extract each variable into a vars/main.yaml, deduplicating with anything else having that value (unless there was a good reason). And then write the .env file for each project. After a couple years of this, we ended up moving more and more into a .env-defaults file. Since I'd kind of paved the way of checking in some localdev creds, we encoded a lot of the copy-pasted secret values into git in each project. Our services run on AWS's SSM Parameter Store. We've talked about trying to mine that for localdev, on and off, but hasn't happened.
