Secret

Secrets and environment variables can be injected into the containers that run your apps. After a secret is saved, it can be used in your application code like this:

from beam import function


@function(secrets=["AWS_ACCESS_KEY"])
def handler():
    import os

    my_secret = os.environ["AWS_ACCESS_KEY"]
    print(f"Secret: {my_secret}")

List Secrets
