Deleting a subnet group - Amazon MemoryDB for Redis
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.

Deleting a subnet group

If you decide that you no longer need your subnet group, you can delete it. You cannot delete a subnet group if it is currently in use by a cluster. You also cannot delete a subnet group on a cluster with Multi-AZ enabled if doing so leaves that cluster with fewer than two subnets. You must first uncheck Multi-AZ and then delete the subnet.

The following procedures show you how to delete a subnet group.

Deleting a subnet group (Console)

To delete a subnet group

  1. Sign in to the Amazon Web Services Management Console and open the MemoryDB for Redis console at https://console.amazonaws.cn/memorydb/.

  2. In the left navigation pane, choose Subnet Groups.

  3. In the list of subnet groups, choose the one you want to delete, choose Actions and then choose Delete.

    Note

    You cannot delete a default subnet group or one that is associated with any clusters.

  4. The Delete Subnet Groups confirmation screen will appear.

  5. To delete the subnet group, enter delete in the confirmation text box. To keep the subnet group, choose Cancel.

Deleting a subnet group (Amazon CLI)

Using the Amazon CLI, call the command delete-subnet-group with the following parameter:

  • --subnet-group-name mysubnetgroup

For Linux, OS X, or Unix:

aws memorydb delete-subnet-group \ --subnet-group-name mysubnetgroup

For Windows:

aws memorydb delete-subnet-group ^ --subnet-group-name mysubnetgroup

For more information, see the Amazon CLI topic delete-subnet-group.

Deleting a subnet group (MemoryDB API)

Using the MemoryDB API, call DeleteSubnetGroup with the following parameter:

  • SubnetGroupName=mysubnetgroup

Example

https://memory-db.us-east-1.amazonaws.com/ ?Action=DeleteSubnetGroup &SubnetGroupName=mysubnetgroup &SignatureMethod=HmacSHA256 &SignatureVersion=4 &Timestamp=20210801T220302Z &Version=2021-01-01 &X-Amz-Algorithm=Amazon4-HMAC-SHA256 &X-Amz-Credential=<credential> &X-Amz-Date=20210801T220302Z &X-Amz-Expires=20210801T220302Z &X-Amz-Signature=<signature> &X-Amz-SignedHeaders=Host

This command produces no output.
