Hello Community, what is the difference in using

dagster

to load env variables, and using the

os

library? e.g.

EnvVar("MY_VAR")

or

os.getenv("MY_VAR")

Using dagsters

EnvVar

resulted in an error for me, as it was returning

MY_VAR

instead of the value of

MY_VAR

- which seems really odd to me. Using

os.getenv

works fine. If there is any documentation that explains the behavior of

EnvVar

, happy to see it! I couldn't find it 🙂 Thanks!

@David Weber If I'm understanding correctly, I believe

EnvVar

is meant to be used for configurable Dagster objects, while

os.getenv

can be used in your code when you want to pass environment variables to non-Dagster objects without using configurable objects. In my experience, when you use

EnvVar

with configurable Dagster objects, you are able to better manage environment variables, as well as keep them hidden in the UI.

After looking into the source code, this is also what I understood now. Thanks for your answer Justin!
