# Use AWS CLI to get the most recent version of an AMI that | |

--filters Name=name,Values=ubuntu/images/hvm-ssd/ubuntu-trusty-14.04-amd64* \ | |
--query 'Images[*].[ImageId,CreationDate]' --output text \ | |

--owners
to limit the account ID to one known to be owned by Canonical. This is a security risk, as anyone can make - and publicly share - an AMI with a similar name, with who-knows-what installed in it.
To just get "ubuntu jammy" and the latest AMI id only:
aws ec2 describe-images --owners 099720109477 --filters 'Name=name,Values=ubuntu/images/hvm-ssd/ubuntu-jammy*' --query 'sort_by(Images, &CreationDate)[-1].[ImageId]' --output text
Only image id with same original command:
AMI_ID=`aws ec2 describe-images \
--filters 'Name=name,Values=ubuntu/images/hvm-ssd/ubuntu-*' \
--query 'Images[*].[ImageId,CreationDate]' --output text \
| sort -k1 -r \
| head -n1 | cut -f 1 -w`
