Output And Evidence

Use Alibaba Cloud OpenAPI (RPC) with official SDKs or OpenAPI Explorer to manage ECS resources. Prefer the Python SDK for all examples and execution.

Prerequisites

API behavior notes (from ECS docs)

Workflow

1) Confirm region, resource identifiers, and desired action. 2) Find API group and exact operation name in references/api_overview.md. 3) Call API with Python SDK (preferred) or OpenAPI Explorer. 4) Verify results with describe/list APIs. 5) If you need repeatable inventory or summaries, use scripts/ and write outputs under output/aliyun-ecs-manage/.

SDK priority

1) Python SDK (preferred) 2) OpenAPI Explorer 3) Other SDKs (only if Python is not feasible)

Python SDK quickstart (list instances)

Virtual environment is recommended (avoid PEP 668 system install restrictions).

python3 -m venv .venv
. .venv/bin/activate
python -m pip install alibabacloud_ecs20140526 alibabacloud_tea_openapi alibabacloud_credentials

from alibabacloud_ecs20140526.client import Client as Ecs20140526Client
from alibabacloud_ecs20140526 import models as ecs_models
from alibabacloud_tea_openapi import models as open_api_models
def create_client(region_id: str) -> Ecs20140526Client:
    config = open_api_models.Config(
        # Use env vars or shared config files per AccessKey priority.
        region_id=region_id,
        endpoint=f"ecs.{region_id}.aliyuncs.com",
    )
    return Ecs20140526Client(config)
def list_instances(region_id: str):
    client = create_client(region_id)
    resp = client.describe_instances(ecs_models.DescribeInstancesRequest(
        region_id=region_id,
        page_number=1,
        page_size=50,
    ))
    for inst in resp.body.instances.instance:
        print(inst.instance_id, inst.instance_name, inst.instance_type, inst.status)
if __name__ == "__main__":
    list_instances("cn-hangzhou")

Python SDK scripts (recommended for inventory)

Python SDK: query one instance resource usage

Install dependencies (add CMS SDK):

python -m pip install alibabacloud_ecs20140526 alibabacloud_cms20190101 alibabacloud_tea_openapi alibabacloud_credentials

Example (last 1 hour, 5-minute period):

python skills/compute/ecs/aliyun-ecs-manage/scripts/query_instance_usage.py \
  --instance-id i-xxxxxxxxxxxxxxxxx \
  --region-id cn-shanghai \
  --hours 1 \
  --period 300 \
  --summary-only \
  --output output/aliyun-ecs-manage/ecs-usage-i-xxxxxxxxxxxxxxxxx-1h.json

Recommended default metrics:

Python SDK: run remote command on one ECS instance

Example (ps -ef):

python skills/compute/ecs/aliyun-ecs-manage/scripts/run_remote_command.py \
  --instance-id i-xxxxxxxxxxxxxxxxx \
  --region-id cn-shanghai \
  --command 'ps -ef' \
  --output output/aliyun-ecs-manage/runcommand-i-xxxxxxxxxxxxxxxxx-ps-ef.json

Behavior:

Python SDK: list instances for all regions

    )
    return Ecs20140526Client(config)
def list_regions() -> list[str]:
    client = create_client("cn-hangzhou")
    resp = client.describe_regions(ecs_models.DescribeRegionsRequest())
    return [r.region_id for r in resp.body.regions.region]
def list_instances_all_regions():

        req = ecs_models.DescribeInstancesRequest(

            page_number=1,
            page_size=100,
        )
        resp = client.describe_instances(req)
        print(f"== {region_id} ({resp.body.total_count}) ==")
        for inst in resp.body.instances.instance:
            print(inst.instance_id, inst.instance_name, inst.instance_type, inst.status)
if __name__ == "__main__":
    list_instances_all_regions()

Cloud Assistant (RunCommand) tips

See references/command-assistant.md.

AccessKey priority (must follow, align with README)

1) Environment variables: ALICLOUD_ACCESS_KEY_ID / ALICLOUD_ACCESS_KEY_SECRET / ALICLOUD_REGION_ID Region policy: ALICLOUD_REGION_ID is an optional default. If unset, decide the most reasonable region for the task; if unclear, ask the user. 2) Shared config file: ~/.alibabacloud/credentials (region still from env)

Auth setup (README-aligned)

Environment variables:

export ALICLOUD_ACCESS_KEY_ID="your-ak"
export ALICLOUD_ACCESS_KEY_SECRET="your-sk"
export ALICLOUD_REGION_ID="cn-hangzhou"

Also supported by the Alibaba Cloud SDKs:

export ALIBABA_CLOUD_ACCESS_KEY_ID="your-ak"
export ALIBABA_CLOUD_ACCESS_KEY_SECRET="your-sk"

Shared config file:

~/.alibabacloud/credentials

[default]
type = access_key
access_key_id = your-ak
access_key_secret = your-sk
