Extract LaunchDarkly feature flags to understand what to clean up

Dependencies

• Python 3.9

Configuration Setup

The LaunchDarkly authentication and project settings are stored in ff_config.yaml

To stop any changes to this file getting back into Git use:

# use --no-skip-worktree to undo
git update-index --skip-worktree ff_config.yaml

LaunchDarkly authentication

Create a personal API access token against your LaunchDarkly account and store it somewhere safe: https://docs.launchdarkly.com/home/account-security/api-access-tokens

Edit ff_config.yaml and set the token. Example:

- launchdarkly:
    token: api-my-token
    project: my-project
    environment: my-environment

Set the project and environment values to the keys that are configured in LaunchDarkly. Environment can be a comma delimited list of values, example:

    environment: my-environment,other-env

audit.py

Extracts the following fields for each feature flag configured in LaunchDarkly in to a .CSV file:

• Key
• On
• Permanent
• Last modified (days)
• Last evaluated (days)
• Created
• Updated
• Owner
• Description
• Tags

The owner is taken from the first part of the email address, everything before @domain. Last modified days is calcuated from today. If a feature flag has never been evaluated, then the Last evaluated value will be blank and 0 means it was evaluated today. The file is created in the data folder and named "feature-flags-YYYY-MM-DD.CSV"

Run

Generates a .CSV file listing the feature flags configured in LaunchDarkly, for the project and environment defined in ff_config.yaml
