<a name="tag-resources-console"></a>

You can add tags to a public repository.

For information about names and best practices for tags, see [Tag naming limits and requirements](https://docs.aws.amazon.com//tag-editor/latest/userguide/tagging.html#tag-conventions) and [Best practices](https://docs.aws.amazon.com//tag-editor/latest/userguide/tagging.html#tag-best-practices) in the *Tagging AWS Resources User Guide*.

When you select a specific repository in the Amazon ECR console, you can view the tags by selecting **Tags** in the navigation pane.

The following examples show how to manage tags using the AWS CLI.

**Example 1: Tag an existing public repository**  
The following command tags an existing public repository.

```
aws ecr-public tag-resource \
      --resource-arn arn:aws:ecr-public::{{account_id}}:repository/{{repository_name}} \
      --tags Key={{stack}},Value={{dev}} \
      --region us-east-1
```

**Example 2: Tag an existing public repository with multiple tags**  
The following command tags an existing repository.

```
aws ecr-public tag-resource \
      --resource-arn arn:aws:ecr-public::{{account_id}}:repository/{{repository_name}} \
      --tags Key={{key1}},Value={{value1}} Key={{key2}},Value={{value2}} Key={{key3}},Value={{value3}} \
      --region us-east-1
```

**Example 3: List tags for a public repository**  
The following command lists the tags that are associated with an existing public repository.

```
aws ecr-public list-tags-for-resource \
      --resource-arn arn:aws:ecr-public::{{account_id}}:repository/{{repository_name}} \
      --region us-east-1
```

**Example 4: Create a public repository and apply a tag**  
The following command creates a public repository that's named `test-repo` and adds a tag with key `team` and value `devs`.

```
