# Adding Tags

Tags are used to identify cloud resources, such as ECSs, images, and disks. If you have multiple types of cloud resources which are associated with each other, you can add tags to the resources to classify and manage them easily. For more details, see Overview.

You can add tags to ECSs in any of the following ways:

- Adding Tags When Creating an ECS
- Adding Tags on the Page Providing Details About an ECS
- Adding Tags on the TMS Console

For details about how to use predefined tags, see Using Predefined Tags.

#### Adding Tags When Creating an ECS

1. Log in to the management console.
2. Click in the upper left corner and select your region and project.
3. Under Computing, click Elastic Cloud Server.
4. Click Create ECS.
5. Configure ECS parameters.

   Select Configure now for Advanced Options. Then, add a tag key and tag value. For the tag key and tag value requirements, see Table 1.

   - For details about other parameters, see "Purchasing an ECS with Customized Configurations".

#### Adding Tags on the Page Providing Details About an ECS

1. Log in to the management console.
2. Click in the upper left corner and select your region and project.
3. Under Computing, click Elastic Cloud Server.
4. On the Elastic Cloud Server page, click the name of the target ECS.

   The page providing details about the ECS is displayed.

5. Click the Tags tab and then Add Tag. In the displayed dialog box, enter the tag key and tag value. For the tag key and tag value requirements, see Table 1.

   You can change the tag value after the tag is added.

#### Adding Tags on the TMS Console

This method is suitable for adding tags with the same tag key to multiple resources.

1. Log in to the management console.
2. Under Management & Deployment, click Tag Management Service.
3. On the displayed Resource Tags page, select the region where the resource is located, select ECS for Resource Type, and click Search.

   All ECSs matching the search criteria are displayed.

4. In the Search Result area, click Create Key. In the displayed dialog box, enter a key (for example project) and click OK.

   After the tag is created, the tag key is added to the resource list. If the key is not displayed in the resource list, click and select the created key from the drop-down list.

   By default, the value of the tag key is Not tagged. You need to set a value for the tag of each resource to associate the tag with the resource.

5. Click Edit to make the resource list editable.
6. Locate the row containing the target ECS, click , and enter a value (for example A).

   After a value is set for a tag key, the number of tags is incremented by 1. Repeat the preceding steps to add tag values for other ECSs.

#### Using Predefined Tags

If you want to add the same tag to multiple ECSs or other resources, you can create a predefined tag on the TMS console and then select the tag for the ECSs or resources. This frees you from having to repeatedly enter tag keys and values. To do so, perform the following operations:

1. Log in to the management console.
2. Under Management & Deployment, click Tag Management Service.
3. In the navigation pane on the left, choose Predefined Tags. In the right pane, click Create Tag enter a key (for example project) and a value (for example A) in the displayed dialog box.
4. Choose Service List > Computing > Elastic Cloud Server, and select the predefined tag by following the procedure for adding a tag.
