Swift

Lithops with OpenStack Swift as storage backend.

Installation

1. Install and configure Keystone

2. Install and configure OpenStack Swift

3. Create a new bucket (container) (e.g. lithops-data). Remember to update the corresponding Lithops config field with this bucket name.

Configuration

1. Edit your Lithops config file and add the following keys:

    lithops:
        storage: swift

    swift:
        storage_bucket: <BUCKET_NAME>
        auth_url: <SWIFT_AUTH_URL>
        region: <SWIFT_REGION>
        user_name: <USER_NAME>
        project_name: <PROJECT_NAME>
        password: <SWIFT_PASSWORD>
        user_domain_name: Default
        project_domain_name: Default

user_id and project_id identify the user and the project by id instead of by name. Set one of each pair. auth_url may or may not end in /v3. endpoint replaces the storage URL published in the Keystone catalog.
