How to access secrets in Livebook code?

[nicksergeant]

I thought I knew Elixir well enough (😅) but am now realizing that all-caps variables in Elixir are not what I expected them to be:

> IO.inspect DOMAIN
DOMAIN

That makes it seem like an Atom, to me. I'm not entirely sure how else I would access secrets in Livebook:

Are they not surfaced in the code as they are represented in the sidebar as all-caps?

Hey @nicksergeant, secrets are accessible as env vars (similarly to env vars defined in the global settings). The only difference is that they have LB_ prefix. So in your case you can do System.fetch_env!("LB_BEARER_TOKEN") :)

@jonatanklosko 🤦 thanks! That makes a lot of sense. I added some help text and submitted a PR if you are interested (totally fine if not!) #1535
