Ubuntu cloud images and how to find the most recent cloud image – part 2/3

TLDR;

sudo snap install image-status

This will install a snap of the very useful `image-status` utility.

image-status cloud-release bionic

This will show you the serial for the most recent Ubuntu 18.04 Bionic cloud image in QCOW format.

image-status ec2-release bionic

This will show you the AWS EC2 AMIs for the most recent Ubuntu 18.04 Bionic AWS EC2 cloud images.


Part two of a three part series.

Following on from part 1 where I detailed simplestreams and sstream-query I present to you the `image-status` utility which is a very neat and useful wrapper around sstream-query.

image-status is hosted on github as part of Scott Moser‘s talk-simplestreams repo.

I recently submitted a pull request which added the ability to package image-status as a snap. This was merged and you can now install image-status on any linux distribution supporting snaps using the following command.

sudo snap install image-status

Once installed you can start querying the simplestreams feeds for details on the most recent Ubuntu cloud images.

Usage:

image-status --help # to see all available options

image-status cloud-release bionic # to see most recent Ubuntu Bionic release images on http://cloud-images.ubuntu.com/
image-status cloud-daily bionic # to see most recent Ubuntu Bionic daily images on http://cloud-images.ubuntu.com/

image-status gce-release bionic # to see most recent Ubuntu Bionic release images on GCE
image-status gce-dailybionic # to see most recent UbuntuBionic daily images on GCE

image-status ec2-release bionic # to see most recent Ubuntu Bionic release AMIs on EC2
image-status ec2-daily bionic # to see most recent UbuntuBionic daily AMIs on EC2

image-status azure-release bionic # to see most recent Ubuntu Bionic release images on Azure
image-status azure-daily bionic # to see most recent UbuntuBionic daily images on Azure

image-status maas-release bionic # to see most recent Ubuntu Bionic release images for maas V2
image-status maas-daily bionic # to see most recent UbuntuBionic daily images for maas V2

image-status maas3-release bionic # to see most recent Ubuntu Bionic release images for maas V3
image-status maas3-daily bionic # to see most recent Ubuntu Bionic daily images for maas V3

I find this very useful when trying to quickly see what is the most recent Ubuntu release on any particular public cloud. eg:

image-status ec2-release bionic | grep eu-west-1 | grep hvm | grep ssd | awk '{split($0,a," "); print a[6]}'

This will return the ID for the most recent HVM EBS Ubuntu 18.04 (Bionic) in the eu-west-1 AWS EC2 region. This can be achieved using sstream-query too but I find filtering using grep to be easier to understand and iterate with.

I hope the above is helpful with your automation.
