Managing Your Cost Allocation Tags Using the AWS CLI

You can use the AWS CLI to add, modify, or remove cost allocation tags.

Sample arn: arn:aws:elasticache:us-west-2:1234567890:cluster:my-cluster

Cost allocation tags are applied to ElastiCache for Redis nodes. The node to be tagged is specified using an ARN (Amazon Resource Name).

Sample arn: arn:aws:elasticache:us-west-2:1234567890:cluster:my-cluster

Listing Tags Using the AWS CLI

You can use the AWS CLI to list tags on an existing ElastiCache resource by using the list-tags-for-resource operation.

The following code uses the AWS CLI to list the tags on the Redis node my-cluster-001 in the my-cluster cluster in region us-west-2.

For Linux, macOS, or Unix:

aws elasticache list-tags-for-resource \ --resource-name arn:aws:elasticache:us-west-2:0123456789:cluster:my-cluster-001

For Windows:

aws elasticache list-tags-for-resource ^ --resource-name arn:aws:elasticache:us-west-2:0123456789:cluster:my-cluster-001

Output from this operation will look something like the following, a list of all the tags on the resource.

{ "TagList": [ { "Value": "10110", "Key": "CostCenter" }, { "Value": "EC2", "Key": "Service" } ] }

If there are no tags on the resource, the output will be an empty TagList.

{ "TagList": [] }

For more information, see the AWS CLI for ElastiCache list-tags-for-resource.

Adding Tags Using the AWS CLI

You can use the AWS CLI to add tags to an existing ElastiCache resource by using the add-tags-to-resource CLI operation. If the tag key does not exist on the resource, the key and value are added to the resource. If the key already exists on the resource, the value associated with that key is updated to the new value.

The following code uses the AWS CLI to add the keys Service and Region with the values elasticache and us-west-2 respectively to the node my-cluster-001 in the cluster my-cluster in region us-west-2.

For Linux, macOS, or Unix:

aws elasticache add-tags-to-resource \ --resource-name arn:aws:elasticache:us-west-2:0123456789:cluster:my-cluster-001 \ --tags Key=Service,Value=elasticache \ Key=Region,Value=us-west-2

For Windows:

aws elasticache add-tags-to-resource ^ --resource-name arn:aws:elasticache:us-west-2:0123456789:cluster:my-cluster-001 ^ --tags Key=Service,Value=elasticache ^ Key=Region,Value=us-west-2

Output from this operation will look something like the following, a list of all the tags on the resource following the operation.

{ "TagList": [ { "Value": "elasticache", "Key": "Service" }, { "Value": "us-west-2", "Key": "Region" } ] }

For more information, see the AWS CLI for ElastiCache add-tags-to-resource.

You can also use the AWS CLI to add tags to a cluster when you create a new cluster by using the operation create-cache-cluster. You cannot add tags when creating a cluster using the ElastiCache management console. After the cluster is created, you can then use the console to add tags to the cluster.

Modifying Tags Using the AWS CLI

You can use the AWS CLI to modify the tags on a node in an ElastiCache for Redis cluster.

To modify tags:

Output from either operation will be a list of tags and their values on the specified cluster.

Removing Tags Using the AWS CLI

You can use the AWS CLI to remove tags from an existing node in an ElastiCache for Redis cluster by using the remove-tags-from-resource operation.

The following code uses the AWS CLI to remove the tags with the keys Service and Region from the node my-cluster-001 in the cluster my-cluster in the us-west-2 region.

For Linux, macOS, or Unix:

aws elasticache remove-tags-from-resource \ --resource-name arn:aws:elasticache:us-west-2:0123456789:cluster:my-cluster-001 \ --tag-keys PM Service

For Windows:

aws elasticache remove-tags-from-resource ^ --resource-name arn:aws:elasticache:us-west-2:0123456789:cluster:my-cluster-001 ^ --tag-keys PM Service

Output from this operation will look something like the following, a list of all the tags on the resource following the operation.

{ "TagList": [] }

For more information, see the AWS CLI for ElastiCache remove-tags-from-resource.
