The command requires the area Amazon Useful resource Title (ARN) and an inventory of tags to be added. Use the next syntax.

add-tags --arn=<domain_arn> --tag-list Key=<key>,Worth=<worth>

Instance:

aws opensearch add-tags –arn arn:aws:es:us-east-1:123456789123:area/opensearchtestdomain –tag-list Key=opensearchdomain,Worth=opensearchtestdomain

Amazon OpenSearch Service configuration API

You should utilize the Amazon OpenSearch Service configuration API to create, configure, and handle OpenSearch Service domains. Use the next AddTags command to tag an OpenSearch Service area.

POST /2021-01-01/tags HTTP/1.1 
Content material-type: software/json 
{ 
    "ARN": "arn:aws:es:us-east-1:123456789123:area/opensearchtestdomain", 
    "TagList": [ 
        { 
            "Key": "opensearchdomain", 
            "Value": "opensearchtestdomain" 
        } 
    ] 
}

AWS SDK

You possibly can programmatically add tags to an OpenSearch Service area utilizing the AWS OpenSearch SDK. The SDK gives strategies to work together with Amazon OpenSearch Service API and handle tags. For instance, Python shopper can use the client.add_tags command to tag a website. You could present values for domain_arn, tag_key, and tag_value.

import boto3 
shopper = boto3.shopper('opensearch') 
response = shopper.add_tags ( 
    ARN = ‘arn:aws:es:us-east-1:123456789123:area/opensearchtestdomain’, 
    TagList=[ 
    { 
        ‘Key’: ‘opensearchdomain’, 
        ‘Value’: ‘opensearchtestdomain’ 
    } 
  ] 
)

AWS CloudFormation or Terraform

When provisioning an OpenSearch Service area utilizing CloudFormation or Terraform, you’ll be able to outline the tags as a part of the useful resource configuration by utilizing AWS::OpenSearchService::Domain Tag.

Assets 
    OpenSearchDomain: 
        Sort: AWS::OpenSearchService::Area 

Properties
    DomainName: arn:aws:es:us-east-1:123456789123:area/opensearchtestdomain

Tags 
    - Key: opensearchdomain 
    - Worth: opensearchtestdomain

After making use of a user-defined tag to the OpenSearch Service area, use the next AWS CLI command to confirm that the tag has been utilized.

aws opensearch list-tags –arn <ARN>

Instance:

aws opensearch list-tags –arn arn:aws:es:us-east-1:123456789123:area/opensearchtestdomain

Troubleshooting

The add-tags command can fail within the following situations, so be sure all of the values are entered appropriately:

• Invalid useful resource ARN – The command will fail if the offered ARN for the OpenSearch Service area is invalid or doesn’t exist.
• Inadequate permissions – Confirm that the IAM consumer or position you’re utilizing to run the OpenSearch Service instructions has the mandatory permissions to entry the OpenSearch Service area and carry out the specified actions, comparable to including tags.
• Exceeded tag restrict – The OpenSearch Service area has limit of up to 10 tags, so if the variety of tags you are attempting so as to add exceeds this restrict, the command will fail.

For ease of use and greatest outcomes, use the Tag Editor to create and apply user-defined tags. The Tag Editor gives a central, unified strategy to create and handle your user-defined tags. For extra info, check with Working with Tag Editor within the AWS Resource Groups User Guide.

Nevertheless, an extreme variety of tags can enhance the dimensions of your CUR file. Your CUR file comprises your utilization and value information, together with tags you apply, so extra tags imply extra information within the file. CUR information is saved in Amazon Simple Storage Service (Amazon S3), so bigger CUR file might enhance storage value.

The very best apply is to be selective about which tags you allow and what number of you utilize. Begin with tags that present essentially the most worth for attributes comparable to value allocation and analytics. Monitor your CUR file measurement over time and add and take away tags thoughtfully.
