Introduction to Aliyun SDK
The Aliyun SDK is a powerful tool that allows developers to easily integrate and manage Alibaba Cloud services. It provides an array of APIs for working with different cloud services, making the development process more efficient and effective.
Key Aliyun SDK API Examples
1. Initialize the SDK
from aliyunsdkcore.client import AcsClient
client = AcsClient('', '', 'cn-shanghai')
2. Create a New ECS Instance
from aliyunsdkecs.request.v20140526.CreateInstanceRequest import CreateInstanceRequest
request = CreateInstanceRequest()
request.set_ImageId('m-bp18m9ob591j8yc1raqz')
request.set_InstanceType('ecs.t1.small')
request.set_SecurityGroupId('sg-uf66jeqopgqa9hdx1pib')
response = client.do_action_with_exception(request)
print(response)
3. Start an ECS Instance
from aliyunsdkecs.request.v20140526.StartInstanceRequest import StartInstanceRequest
request = StartInstanceRequest()
request.set_InstanceId('i-uf6wijb1cehx5y0vizw')
response = client.do_action_with_exception(request)
print(response)
4. Stop an ECS Instance
from aliyunsdkecs.request.v20140526.StopInstanceRequest import StopInstanceRequest
request = StopInstanceRequest()
request.set_InstanceId('i-uf6wijb1cehx5y0vizw')
response = client.do_action_with_exception(request)
print(response)
5. Describe Instances
from aliyunsdkecs.request.v20140526.DescribeInstancesRequest import DescribeInstancesRequest
request = DescribeInstancesRequest()
request.set_PageSize(10)
response = client.do_action_with_exception(request)
print(response)
Full App Integration with Aliyun SDK
Using the above APIs, we can create a simple application to manage ECS instances:
app.py
from flask import Flask, jsonify, request
from aliyunsdkcore.client import AcsClient
from aliyunsdkecs.request.v20140526.CreateInstanceRequest import CreateInstanceRequest
from aliyunsdkecs.request.v20140526.StartInstanceRequest import StartInstanceRequest
from aliyunsdkecs.request.v20140526.StopInstanceRequest import StopInstanceRequest
from aliyunsdkecs.request.v20140526.DescribeInstancesRequest import DescribeInstancesRequest
app = Flask(__name__)
client = AcsClient('', '', 'cn-shanghai')
@app.route('/create_instance', methods=['POST'])
def create_instance():
data = request.json
req = CreateInstanceRequest()
req.set_ImageId(data['ImageId'])
req.set_InstanceType(data['InstanceType'])
req.set_SecurityGroupId(data['SecurityGroupId'])
response = client.do_action_with_exception(req)
return jsonify(response)
@app.route('/start_instance', methods=['POST'])
def start_instance():
instance_id = request.json['InstanceId']
req = StartInstanceRequest()
req.set_InstanceId(instance_id)
response = client.do_action_with_exception(req)
return jsonify(response)
@app.route('/stop_instance', methods=['POST'])
def stop_instance():
instance_id = request.json['InstanceId']
req = StopInstanceRequest()
req.set_InstanceId(instance_id)
response = client.do_action_with_exception(req)
return jsonify(response)
@app.route('/describe_instances', methods=['GET'])
def describe_instances():
req = DescribeInstancesRequest()
req.set_PageSize(10)
response = client.do_action_with_exception(req)
return jsonify(response)
if __name__ == '__main__':
app.run(debug=True)
By utilizing the Aliyun SDK and the provided code snips, you can now effectively manage your Alibaba Cloud ECS instances within a full-fledged application.
