AWS Resource Explorer now provides immediate access to resource search and discovery capabilities in a Region. With this launch, you no longer need to activate Resource Explorer to discover your resources. Learn more

Adding tags to views

You can add tags to your views to categorize them. Tags are customer-supplied metadata that take the form of a key name string and an associated optional value string. For general information about tagging AWS resources, see Tagging AWS Resources in the Amazon Web Services General Reference.

Add tags to your views

You can add tags to your Resource Explorer views by using the AWS Management Console or by running AWS CLI commands or their equivalent API operations in an AWS SDK.

AWS Management Console

To add tags to a view

1. Open the Resource Explorer Views page and choose the name of the view that you want to tag to display its Details page.

2. Under Tags, choose Manage tags.

3. To add a tag, choose Add tag and then enter a tag key name and optional value.

   Note

   You can also delete a tag by choosing the X next to the tag.

   You can attach up to 50 user-defined tags to a resource. Any tags that are created and managed automatically by AWS don't count against this quota.

4. When you're done with all tag changes, choose Save changes.

AWS CLI

To add tags to a view

Run the following command to add tags to a view. The following example add tags with the key name environment and the value production to the specified view.

$ aws resource-explorer-2 tag-resource \
    --resource-id arn:aws:resource-explorer-2:us-east-1:123456789012:view/MyViewName/1a2b3c4d-5d6e-7f8a-9b0c-abcd11111111 \
    --tags environment=production

The preceding command produces no output if it succeeds.

Note

To remove an existing tag from a view, use the untag-resource command.

Controlling permissions with tags

One key use of tagging is to support an attribute-based access control (ABAC) strategy. ABAC can help simplify permission management by letting you tag resources. Then, you grant permission to users for resources that are tagged a certain way.

For example, consider this scenario. For a view called ViewA, you attach the tag environment=prod (key name=value). Another ViewB might be tagged environment=beta. You tag your roles and users with the same tags and values, based on which environment each role or user should be able to access.

Then, you could assign an AWS Identity and Access Management (IAM) permission policy to your IAM roles, groups, and users. The policy grants permission to access and search using a view only if the role or user making the search request has an environment tag with the same value as the environment tag attached to the view.

The benefit to this approach is that it's dynamic and doesn't require you to maintain a list of who has access to which resources. Instead, you ensure that all resources (your views) and principals (IAM roles and users) are tagged properly. Then, the permissions update automatically without you having to change any policies.

Referencing tags in an ABAC policy

After your views are tagged, you can choose to use those tags to control access dynamically to those views. The following example policy assumes that both your IAM principals and your views are tagged with the tag key environment and some value. When that is done, you can attach the following example policy to your principals. Your roles and users can then Search using any views that are tagged with an environment tag value that exactly matches the environment tag attached to the principal.

If both the principal and view have the environment tag but the values don't match, or if either is missing the environment tag then Resource Explorer denies the search request.
