In my service, there is an environment variable called GPG_KEY which I never set. What is the purpose/meaning of this, and is it safe to share publicly?
We do set some default environment variables. However, GPG_KEY is not one of them. You may have forgotten adding it some point, used a Blueprint that hardcoded it, or inherited it from a Docker image.
I’m using Python 3 runtime, not docker. I can confirm I definitely did not create the environment variable. I do not use blueprints.
Ah, it looks like it does get pulled in with Python. It’s a public key and is set in publicly-accessible official Docker images for Python.
