Managing your cost allocation tags using the ElastiCache API

You can use the ElastiCache API to add, modify, or remove cost allocation tags.

Cost allocation tags are applied to ElastiCache for Memcached 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 ElastiCache API

You can use the ElastiCache API to list tags on an existing resource by using the ListTagsForResource operation.

The following code uses the ElastiCache API to list the tags on the resource my-cluster-001 in the us-west-2 region.

https://elasticache.us-west-2.amazonaws.com/
   ?Action=ListTagsForResource
   &ResourceName=arn:aws:elasticache:us-west-2:0123456789:cluster:my-cluster-001
   &SignatureVersion=4
   &SignatureMethod=HmacSHA256
   &Version=2015-02-02
   &Timestamp=20150202T192317Z
   &X-Amz-Credential=<credential>

Adding tags using the ElastiCache API

You can use the ElastiCache API to add tags to an existing ElastiCache cluster by using the AddTagsToResource 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 ElastiCache API to add the keys Service and Region with the values elasticache and us-west-2 respectively to the resource my-cluster-001 in the us-west-2 region. 

https://elasticache.us-west-2.amazonaws.com/
   ?Action=AddTagsToResource
   &ResourceName=arn:aws:elasticache:us-west-2:0123456789:cluster:my-cluster-001
   &SignatureVersion=4
   &SignatureMethod=HmacSHA256
   &Tags.member.1.Key=Service 
   &Tags.member.1.Value=elasticache
   &Tags.member.2.Key=Region
   &Tags.member.2.Value=us-west-2
   &Version=2015-02-02
   &Timestamp=20150202T192317Z
   &X-Amz-Credential=<credential>

For more information, see AddTagsToResource in the Amazon ElastiCache API Reference.

Modifying tags using the ElastiCache API

You can use the ElastiCache API to modify the tags on an ElastiCache cluster.

To modify the value of a tag:

  • Use AddTagsToResource operation to either add a new tag and value or to change the value of an existing tag.

  • Use RemoveTagsFromResource to remove tags from the resource.

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

Use RemoveTagsFromResource to remove tags from the resource.

Removing tags using the ElastiCache API

You can use the ElastiCache API to remove tags from an existing ElastiCache (Redis OSS) node by using the RemoveTagsFromResource operation.

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

https://elasticache.us-west-2.amazonaws.com/
   ?Action=RemoveTagsFromResource
   &ResourceName=arn:aws:elasticache:us-west-2:0123456789:cluster:my-cluster-001
   &SignatureVersion=4
   &SignatureMethod=HmacSHA256
   &TagKeys.member.1=Service
   &TagKeys.member.2=Region
   &Version=2015-02-02
   &Timestamp=20150202T192317Z
