Impact Framework Eco CI Plugin

Overview

The EcoCI plugin retrieves the energy and the carbon of the workflow of the given repository using the Green Coding API, if the workflow of the repository is listed in the CI projects.

Implementation

The EcoCI plugin fetches the energy and carbon of the specified workflow from the Green Coding API for each entry in a manifest's input data.

• The timestamp and duration fields in the input data are used to filter the energy and carbon data. The relevant endpoint is documented here.

Usage

To run the EcoCI plugin, an instance of ExecutePlugin must be created. Then, the plugin's execute() method can be called, passing the required arguments to it.

This is how you could run the model in Typescript:

async function runPlugin() {
  const config = {
    repo: 'Green-Software-Foundation/if',
    branch: 'main',
    workflow: 66389738,
  };
  const parameterMetadata = { inputs: {}, output: {} };
  const ecoCi = EcoCI(config, parameterMetadata, {});
  const usage = await ecoCi.execute([
    {
      timestamp: '2024-07-09T00:00',
      duration: 126000,
    },
  ]);

  console.log(usage);
}

runPlugin();

Config

• repo: (required) string specifies the name of the organization (or owner) and repository name, combined with /, e.g. Green-Software-Foundation/if
• branch: (required) string specifies the branch of the repository. You can also use the all option to retrieve data for all branches within the specified time range
• workflow: (required) number specifies the workflow id of the repository
• start-date: (optional) string specifies the start of the time range for retrieving data. If not provided, the plugin defaults to using a timestamp from the input.
• end-date: (optional) string specifies the end of the time range. If not provided, the plugin defaults to using the duration from the input.

Input Parameters

• timestamp: (required) specifies the start of the time range for retrieving data from the EcoCI API.
• duration: (required) specifies the end of the time range for retrieving data from the API. It can be either number or string like 24 * 60 * 60.

Mapping

The mapping block is an optional block. It is added in the plugin section and allows the plugin to map the output parameters of the plugin. The structure of the mapping block is:

eco-ci-plugin:
  path: if-eco-ci-plugin
  method: EcoCI
  mapping:
    energy: 'energy-used-in-if-all'
    carbon: 'carbon-used-in-if-all'

Output

• energy: output the size of the given repository, represented in GB.
• carbon: output the clones count of the given repository in the specified time range.

Error Handling

The plugin can throw the following errors:

• APIRequestError: caused by a problem retrieving data from the API. The error message returned from the API is echoed in the IF error message.
• InputValidationError: thrown when some data in the input is incorrect or missing.
• ConfigError: thrown when some data in the global config is incorrect or missing.

Integration into Impact Framework

Clone this repository to your local machine to play with a local copy. In the project root run npm run build && npm link.

This creates a package with global scope on your local machine that can be installed by your instance of Impact Framework.

Navigate to the Impact Framework root, and run npm link if-eco-ci-plugin.

Now, you can use the plugin by including it in your manifest file as follows:

name: eco-ci demo
description:
tags:
initialize:
  plugins:
    ci/cd:
      method: EcoCI
      path: 'if-eco-ci-plugin'
      config:
        repo: 'Green-Software-Foundation/if'
        branch: all
        workflow: 66389738
        start-date: 2024-07-24T10:30
        end-date: 2024-08-14T10:30
      mapping:
        energy: 'energy-used-in-if-all'
        carbon: 'carbon-used-in-if-all'
tree:
  children:
    child:
      pipeline:
        compute:
          - ci/cd
      inputs:
        - timestamp: 2024-07-09T00:00
          duration: 24 * 60 * 60

Now, when you run the manifest using the IF CLI, it will load the model automatically. Run using:

if-run -m <path-to-your-manifest>

References

The plugin simply grabs data for a given repository from the Green Coding API.

• To calculate energy and carbon, the plugin uses this endpoint.
