[SOLVED] aws describe-instances query tags

Issue

I'm trying to filter my output for describe-instances tot show the following:
- instanceId
- Device + Volume - Tag[Key==Name]

The expression I have is

 aws ec2 describe-instances --filters Name=instance-state-name,Values=running --query "Reservations[*].Instances[].[InstanceId, BlockDeviceMappings[*].{DeviceName:DeviceName,VolumeName:Ebs.VolumeId}, Tags[*]]"

But this gives me output where all the tags are showing. How can I change this to only the "Name" tag?

Solution

You are looking for a JMESPath Filter Expression. Try this:

aws ec2 describe-instances \
    --filters Name=instance-state-name,Values=running \
    --query 'Reservations[*].Instances[].[InstanceId, BlockDeviceMappings[*].{DeviceName:DeviceName,VolumeName:Ebs.VolumeId}, Tags[?Key==`Name`]]'
