Improvements

Fix using email addresses as usernames for Argo Workflows

Using an email address as the username when deploying with a @project decorator to Argo Workflows is now possible. This release fixes an issue with some generated resources containing characters that are not permitted in names of Argo Workflow resources.

The secrets decorator now supports assuming roles

This release adds the capability to assume specific roles when accessing secrets with the @secrets decorator. The role for accessing a secret can be defined in the following ways

As a global default

By setting the METAFLOW_DEFAULT_SECRET_ROLE environment variable, this role will be assumed when accessing any secret specified in the decorator.

As a global option in the decorator

This will assume the role secret-iam-role for accessing all of the secrets in the sources list.

@secrets(
  sources=["first-secret-source", "second-secret-source"],
  role="secret-iam-role"
)

Or on a per secret basis

Assuming a different role based on the secret in question can be done as well

@secrets(
  sources=[
    {"type": "aws-secrets-manager", "id": "first-secret-source", "role": "first-secret-role"},
    {"type": "aws-secrets-manager", "id": "second-secret-source", "role": "second-secret-role"}
  ]
)
