Overview

An AIOHTTP based Python REST client for the Docker Registry.

Getting Started

import asyncio
import json
from docker_registry_client_async import DockerRegistryClientAsync, FormattedSHA256, ImageName, Manifest

async def get_config(drca: DockerRegistryClientAsync, image_name: ImageName, manifest: Manifest) -> bytes:
    config_digest = FormattedSHA256.parse(manifest.get_json()["config"]["digest"])
    result = await drca.get_blob(image_name, config_digest)
    return json.loads(result["blob"].decode("utf-8"))

async def get_manifest(drca: DockerRegistryClientAsync, image_name: ImageName) -> Manifest:
    result = await drca.get_manifest(image_name)
    return result["manifest"]

async def main():
    image_name = ImageName.parse("busybox:1.30.1")
    async with DockerRegistryClientAsync() as drca:
        manifest = await get_manifest(drca, image_name)
        config = await get_config(drca, image_name, manifest)
        print(config)

if __name__ == "__main__":
    loop = asyncio.get_event_loop()
    loop.run_until_complete(main())
