Tag a public key

To help categorize and manage the public keys that you've either created using Amazon EC2 or imported to Amazon EC2, you can tag them with custom metadata. For more information about how tags work, see Tag your Amazon EC2 resources.

You can view, add, and delete tags using one of the following methods.

Console

To view, add, or delete a tag for a public key

1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.

2. In the navigation pane, choose Key Pairs.

3. Select a public key, and then choose Actions, Manage tags.

4. The Manage tags page displays any tags that are assigned to the public key.

   • To add a tag, choose Add tag, and then enter the tag key and value. You can add up to 50 tags per key. For more information, see Tag restrictions.

   • To delete a tag, choose Remove next to the tag to delete.

5. Choose Save.

AWS CLI

To view public key tags

Use the describe-tags AWS CLI command. In the following example, you describe the tags for all of your public keys.

$ aws ec2 describe-tags --filters "Name=resource-type,Values=key-pair"

{
    "Tags": [
    {
        "Key": "Environment",
        "ResourceId": "key-0123456789EXAMPLE",
        "ResourceType": "key-pair",
        "Value": "Production"
    },
    {
        "Key": "Environment",
        "ResourceId": "key-9876543210EXAMPLE",
        "ResourceType": "key-pair",
        "Value": "Production"
    }]
}

To describe the tags for a specific public key

Use the describe-key-pairs AWS CLI command.

$ aws ec2 describe-key-pairs --key-pair-ids key-0123456789EXAMPLE

{
    "KeyPairs": [
    {
        "KeyName": "MyKeyPair",
        "KeyFingerprint": "1f:51:ae:28:bf:89:e9:d8:1f:25:5d:37:2d:7d:b8:ca:9f:f5:f1:6f",
        "KeyPairId": "key-0123456789EXAMPLE",
        "Tags": [
        {
            "Key": "Environment",
            "Value": "Production"
        }]			
    }]
}
