Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Managing your cost allocation tags using the Amazon CLI

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

Cost allocation tags are applied to ElastiCache clusters. The cluster 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 Amazon CLI

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

The following code uses the Amazon CLI to list the tags on the Memcached cluster my-cluster in the us-west-2 region.

For Linux, OS X, or Unix:

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

For Windows:

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

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

For Linux, OS X, 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 Amazon CLI for ElastiCache list-tags-for-resource.

Adding tags using the Amazon CLI

You can use the Amazon 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 Amazon 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.

Memcached

For Linux, OS X, or Unix:

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

Redis

For Linux, OS X, 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 Amazon CLI for ElastiCache add-tags-to-resource.

You can also use the Amazon 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 Amazon CLI

You can use the Amazon CLI to modify the tags on an ElastiCache 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 Amazon CLI

You can use the Amazon CLI to remove tags from an existing ElastiCache for Memcached cluster by using the remove-tags-from-resource operation.

For Memcached, the following code uses the Amazon 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, OS X, or Unix:

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

For Windows:

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

For Redis OSS, the following code uses the Amazon 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, OS X, 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 Amazon CLI for ElastiCache remove-tags-from-resource.
