List all volumes attached to list of instances using aws cli

This command will output:

• The value associated with the 'Name' tag
• Instance ID

• EBS Volume ID

  aws ec2 describe-instances --query 'Reservations[*].Instances[*].[Tags[?Key==`Name`].Value,InstanceId,BlockDeviceMappings[*].Ebs.VolumeId]' --output text
  
  i-0d9c9b94b6583af4c

There might be multiple EBS volumes associated with an instance.

In my case i needed to list all stopped instances and associated volumes for a clean up of cloud resources and cost savings. The following code will do the job for you. If you set it to json output is human friendly.

aws ec2 describe-instances --filters "Name=instance-state-name,Values=stopped" --query 'Reservations[*].Instances[*].[Tags[?Key==`Name`].Value,InstanceId,BlockDeviceMappings[*].Ebs.VolumeId]' --output text
