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.
