Elastic Compute Service (ECS)

Validation

mkdir -p output/aliyun-ecs-manage
python -m py_compile skills/compute/ecs/aliyun-ecs-manage/scripts/list_instances_all_regions.py
python -m py_compile skills/compute/ecs/aliyun-ecs-manage/scripts/query_instance_usage.py
python -m py_compile skills/compute/ecs/aliyun-ecs-manage/scripts/run_remote_command.py
echo "py_compile_ok" > output/aliyun-ecs-manage/validate.txt

Pass criteria: command exits 0 and output/aliyun-ecs-manage/validate.txt is generated.

Output And Evidence

• Save list/summarize outputs under output/aliyun-ecs-manage/.
• Keep command arguments and region scope in each evidence file.

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

• Prepare AccessKey (RAM user/role with least privilege).
• Choose the correct region and endpoint (public/VPC).
• ECS OpenAPI is RPC style; prefer SDK or OpenAPI Explorer to avoid manual signing.

API behavior notes (from ECS docs)

• Most list/describe APIs support pagination via PageNumber + PageSize or NextToken + MaxResults.
• DescribeInstances returns an empty list if the RAM user/role lacks permissions; use DryRun to validate permissions.
• For DescribeInstances, NextToken + MaxResults is the recommended paged query pattern; use the returned NextToken to fetch subsequent pages.
• DescribeInstances requires RegionId in the request even if the client has a region set.
• Filters are ANDed; set only the filters you need.

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)

• List all instances across regions (TSV/JSON): scripts/list_instances_all_regions.py
• Query resource usage (CPU/Memory/Network) for one instance: scripts/query_instance_usage.py
• Run remote commands via Cloud Assistant (RunCommand): scripts/run_remote_command.py
• Summarize instance specs across regions: scripts/summary_instance_specs.py
• Summarize instance counts by region (optional status breakdown): scripts/summary_instances_by_region.py
• Summarize instance counts by status: scripts/summary_instances_by_status.py
• Summarize instance counts by instance type: scripts/summary_instances_by_instance_type.py
• Summarize instance counts by VPC: scripts/summary_instances_by_vpc.py
• Summarize instance counts by security group: scripts/summary_instances_by_security_group.py

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:

• CPUUtilization
• memory_usedutilization
• InternetInRate, InternetOutRate
• IntranetInRate, IntranetOutRate

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:

• Submit RunCommand with RunShellScript.
• Poll DescribeInvocationResults until final status.
• Decode base64 stdout and save normalized JSON evidence.

Common operation mapping

• Instance lifecycle: RunInstances, CreateInstance, StartInstance(s), StopInstance(s), RebootInstance(s), DeleteInstance(s)
• Instance details: DescribeInstances, DescribeInstanceStatus, DescribeInstanceAttribute
• Spec changes: ModifyInstanceSpec, ModifyPrepayInstanceSpec, DescribeResourcesModification
• System disk changes: ReplaceSystemDisk, ResetDisk
• Data disks: CreateDisk, AttachDisk, DetachDisk, ResizeDisk, DescribeDisks
• Snapshots: CreateSnapshot, CopySnapshot, DescribeSnapshots, DeleteSnapshot
• Images: CreateImage, CopyImage, DescribeImages, DeleteImage, ModifyImageAttribute
• Security groups: CreateSecurityGroup, AuthorizeSecurityGroup, RevokeSecurityGroup, DescribeSecurityGroupAttribute
• Key pairs: CreateKeyPair, ImportKeyPair, DescribeKeyPairs, DeleteKeyPairs
• ENI: CreateNetworkInterface, AttachNetworkInterface, DetachNetworkInterface, DescribeNetworkInterfaces
• Tags: TagResources, UntagResources, ListTagResources
• Monitoring/events: DescribeInstancesFullStatus, DescribeInstanceHistoryEvents, DescribeInstanceMonitorData

Query patterns

• List instances: DescribeInstances (supports filters such as VpcId, VSwitchId, ZoneId, SecurityGroupId, InstanceIds)
• Count instances: DescribeInstances with PageSize=1 and read TotalCount
• Region discovery: DescribeRegions then loop all regions for inventory

Cloud Assistant (RunCommand) tips

• Instances must be in Running state.
• Ensure the Cloud Assistant agent is installed and online.
• Use shell for Linux, PowerShell for Windows.
• Poll results via DescribeInvocations and DescribeInvocationResults.

See references/command-assistant.md.

AccessKey priority (must follow, align with README)

1. Environment variables: ALIBABACLOUD_ACCESS_KEY_ID / ALIBABACLOUD_ACCESS_KEY_SECRET / ALIBABACLOUD_REGION_ID Region policy: ALIBABACLOUD_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 ALIBABACLOUD_ACCESS_KEY_ID="your-ak"
export ALIBABACLOUD_ACCESS_KEY_SECRET="your-sk"
export ALIBABACLOUD_REGION_ID="cn-hangzhou"

Also supported by the Alibaba Cloud SDKs:

export ALIBABACLOUD_ACCESS_KEY_ID="your-ak"
export ALIBABACLOUD_ACCESS_KEY_SECRET="your-sk"

Shared config file:

~/.alibabacloud/credentials

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

API discovery

• Product code: Ecs
• Default API version: 2014-05-26
• Use OpenAPI metadata endpoints to list APIs and get schemas (see references).

Output policy

If you need to save responses or generated artifacts, write them under: output/aliyun-ecs-manage/

Resource usage query evidence example: output/aliyun-ecs-manage/ecs-usage-<instance-id>-<window>.json

Remote command evidence example: output/aliyun-ecs-manage/runcommand-<instance-id>-<name>.json
