Agent CLI

This repository contains the command-line interface (CLI) tool for interacting with the Agent and manager service. The CLI allows you to perform various tasks such as running computations, uploading algorithm and datasets, and retrieving results.

Build

From the project root:

make cli

Usage

Get attestation

Retrieves attestation information from the SEV guest and saves it to a file. To retrieve attestation from agent, use the following command:

./build/cocos-cli agent attestation get '<report_data>'

Validate attestation

Validates the retrieved attestation information against a specified policy and checks its authenticity. To validate and verify attestation from agent, use the following command:

./build/cocos-cli agent attestation validate '<attestation>' --report_data '<report_data>'

Flags

Upload Algorithm

To upload an algorithm, use the following command:

./build/cocos-cli agent algo /path/to/algorithm <private_key_file_path>

Upload Dataset

To upload a dataset, use the following command:

./build/cocos-cli agent data /path/to/dataset.csv <private_key_file_path>

Retrieve result

To retrieve the computation result, use the following command:

./build/cocos-cli agent result <private_key_file_path>
