You can use Resource Orchestration Service (ROS) to create stacks and create resources within the stacks. To facilitate subsequent O&M, you can also bind tags to your resources by using ROS. ROS allows you to batch bind or update tags for multiple resources at a time to enhance O&M efficiency.

Background information

In this topic, ROS SDK for Python is used to create stacks. For more information, see Use SDK for Python.

Bind the same tag to multiple cloud resources

In the following example, ROS is used to create a virtual private cloud (VPC) named mytest-vpc and a vSwitch named mytest-vsw-h. An app:test tag is also bound to both the VPC and vSwitch.

  1. Create a template. 
    {
  "ROSTemplateFormatVersion": "2015-09-01",
  "Resources": {
    "VPC": {
      "Type": "ALIYUN::ECS::VPC",
      "Properties": {
        "VpcName": "mytest-vpc"
      }
    },
    "VSwitch": {
      "Type": "ALIYUN::ECS::VSwitch",
      "Properties": {
        "VpcId": { "Ref": "VPC" },
        "ZoneId": "cn-hangzhou-h",
        "CidrBlock": "172.16.0.0/24",
        "VSwitchName": "mytest-vsw-h"
      }
    }
  }
}

    In the template, a VPC and a vSwitch are created.

  2. Create a stack and bind the app:test tag to the VPC and vSwitch. 
    # pip install aliyun-python-sdk-ros
import json
from aliyunsdkcore.client import AcsClient
from aliyunsdkros.request.v20190910.CreateStackRequest import CreateStackRequest

client = AcsClient(
    '<AccessKeyId>',
    '<AccessKeySecret>',
    'cn-hangzhou',
)
template = '''
<Template>
'''

req = CreateStackRequest()
req.set_StackName('vpc-vswitch-test')
req.set_TemplateBody(template)
req.set_TimeoutInMinutes(10)
req.set_Tags([{'Key': 'app', 'Value': 'test'}])
ret = client.do_action_with_exception(req)
print(ret)

    Parameter description:

    • Replace <AccessKeyId> and <AccessKeySecret> with your AccessKey ID and AccessKey secret.
    • Replace <Template> with the template created in Step 1.
  3. Optional:Log on to the VPC console and check whether the tag is bound to both the VPC and the vSwitch.

Bind different tags to different cloud resources

In the following example, ROS is used to create a VPC named mytest-vpc and a vSwitch named mytest-vsw-h. An app:test tag is bound to both the VPC and the vSwitch, and a group:test tag is bound only to the vSwitch. Result description:
  • The tag bound to the mytest-vpc VPC is app:test.
  • The tags bound to mytest-vsw-h are app:test and group:test.
  1. Create a template. 
    {
  "ROSTemplateFormatVersion": "2015-09-01",
  "Resources": {
    "VPC": {
      "Type": "ALIYUN::ECS::VPC",
      "Properties": {
        "VpcName": "mytest-vpc"
      }
    },
    "VSwitch": {
      "Type": "ALIYUN::ECS::VSwitch",
      "Properties": {
        "VpcId": { "Ref": "VPC" },
        "ZoneId": "cn-hangzhou-h",
        "CidrBlock": "172.16.0.0/24",
        "VSwitchName": "mytest-vsw-h",
        "Tags": [{ "Key": "group", "Value": "test" }]
      }
    }
  }
}

    A VPC and a vSwitch are created, and the group:test tag is bound to the vSwitch.

  2. Create a stack and bind the app:test tag to the VPC and vSwitch. 
    # pip install aliyun-python-sdk-ros
import json
from aliyunsdkcore.client import AcsClient
from aliyunsdkros.request.v20190910.CreateStackRequest import CreateStackRequest

client = AcsClient(
    '<AccessKeyId>',
    '<AccessKeySecret>',
    'cn-hangzhou',
)
template = '''
<Template>
'''

req = CreateStackRequest()
req.set_StackName('vpc-vswitch-test')
req.set_TemplateBody(template)
req.set_TimeoutInMinutes(10)
req.set_Tags([{'Key': 'app', 'Value': 'test'}])
ret = client.do_action_with_exception(req)
print(ret)

    Parameter description:

    • Replace <AccessKeyId> and <AccessKeySecret> with your AccessKey ID and AccessKey secret.
    • Replace <Template> with the template created in Step 1.
  3. Optional:Log on to the VPC console and check whether

    the app:test tag is bound to the VPC and whether the app:test and group:test tags are bound to the vSwitch.

Update tags for multiple cloud resources

In the following example, the app:test tag bound to mytest-vpc and mytest-vsw-h in the Bind the same tag to multiple cloud resources section is changed to app:normal.

  1. Create a stack and bind the app:normal tag to the VPC and vSwitch. 
    # pip install aliyun-python-sdk-ros
import json
from aliyunsdkcore.client import AcsClient
from aliyunsdkros.request.v20190910.UpdateStackRequest import UpdateStackRequest

client = AcsClient(
    '<AccessKeId>',
    '<AccessKeySecret>',
    'cn-hangzhou',
)
template = '''
<Template>
'''

req = UpdateStackRequest()
req.set_StackId('<StackId>')
req.set_TemplateBody(template)
req.set_Tags([{'Key': 'app', 'Value': 'normal'}])
ret = client.do_action_with_exception(req)
print(ret)

    Parameter description:

  2. Optional:Log on to the VPC console and check whether

    the app:normal tag is bound to the VPC and vSwitch.
