If you have multiple Elastic Compute Service (ECS) resources of different types that
are associated with each other within your account, you can add tags to these resources.
This allows you to categorize and manage the resources in a centralized manner. This
topic describes how to create or add tags to resources in the ECS console.
Background information
- For information about resources that support tags, see Overview.
- You can add up to 20 tags to a resource. If the number of tags that are added to a
resource reaches the upper limit, you must remove some of the tags before you add
new tags.
Procedure
- Log on to the ECS console.
- In the left-side navigation pane, click Tags.
- In the top navigation bar, select a region.
- On the Custom Tags tab, click Create Custom Tags.
- On the Create Custom Tags dialog box, perform the following steps:
When you create custom tags, you must add the tags to resources. Up to 10 custom tags
can be created at the same time, and each custom tag key must be unique. If you want
to create tags but not to add them to resources, create the tags as preset tags. For
more information, see
