Assign output from AWS CLI command to 2nd AWS CLI command

Question

I am writing automation task for creating AWS AMI image, the goal is get output from aws import-image (.ova to ami convert) and add the name in 2nd command:

importaskid=$(aws ec2 import-image --disk-containers  Format=ova,UserBucket="{S3Bucket=acp17,S3Key=XXXXX.ova}" | jq -r '.ImportTaskId')

aws ec2 create-tags --resources echo $importaskid --tags 'Key=Name, Value=acp_ami_test'

I am able to $importaskid and see needed output but when use aws ec2 create-tags the AMI image created without name and the output from 2nd command is empty.

Appreciate your assistance.

Answer 1

This should work for you:

# set bash variable "importaskid":
importaskid=$(aws ec2 import-image --disk-containers Format=ova,UserBucket="{S3Bucket=acp17,S3Key=XXXXX.ova}" | jq -r '.ImportTaskId')

# Verify that importaskid is set correctly
echo $importaskid

# Now use it:
aws ec2 create-tags --resources "$importaskid" --tags 'Key=Name, Value=acp_ami_test'

The "$()" syntax for assigning the output of a command to a variable is discussed here: https://www.cyberciti.biz/faq/unix-linux-bsd-appleosx-bash-assign-variable-command-output/

The double quotes in "$importaskid" would be necessary if the value of "$importaskid" happens to have spaces in it.

'Hope that helps!

thanks for reply, so when i run the command without echo $ImportTaskId see below

aws ec2 create-tags --resource import-ami-XXXXXXXXXXXXX --tags Key=Name,Value='name_ami_test'

i got empty response and the name is not assigned in aws console so i will speak to AWS support/check syntax /check after the assign name to AMI ID and not to import-ami-XXXXXXXXXXXXXXXX
