Storing Secrets and Environment Variables

Secrets and environment variables can be injected into the containers that run your apps.

You can manage secrets through the CLI:

$ beam secret create AWS_ACCESS_KEY ASIAY34FZKBOKMUTVV7A

=> Created secret with name: 'AWS_ACCESS_KEY'

​
Using Secrets

Once created, you can access a secret like an environment variable:

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}")

​
Passing Secrets to on_start

If your app used an on_start function, secrets can be passed to that function as well.

from beam import endpoint


# This has access to secrets passed down in the handler
def load_models():
    import os

    my_secret = os.environ["AWS_ACCESS_KEY"]
    print("The function can read secrets:", my_secret)


@endpoint(
    secrets=["AWS_ACCESS_KEY"],
    on_start=load_models,
)
def handler(context):
    return {}

​
