overview
img-proof (IPA) provides a command line utility to test
images in the Public Cloud (AWS, Azure, GCE, etc.).
With img-proof you can now test custom images in a cloud framework agnostic way
with one tool and one API. In the first release, img-proof supports the
openSUSE and SLES distributions. It also supports the three largest
cloud frameworks (AWS, Azure and GCE). However, it is intended to be
distribution agnostic and framework transparent so both are easily
extensible.
For each distribution there are specific synchronization points that
must be provided. These currently include soft reboot and system update.
The synch points not only test functionality but also act as dividers to
separate distinct sections of a test suite. For example you can run a
test to ensure the proper repos exist before and after a system update.
The system update synch point will guarantee the order of tests.
Speaking of tests, if you're already familiar with Pytest conventions
there's no need to learn a whole new unit testing framework. img-proof is
written in Python and leverages the Pytest framework through Testinfra.
Installation
To install the package use the following commands as root:
$ zypper ar http://download.opensuse.org/repositories/Cloud:/Tools/<distribution>
$ zypper refresh
$ zypper in python3-img-proof
Requirements

Tests
img-proof uses the Testinfra package for writing unit tests. Testinfra
leverages Pytest and provides modules such as Package, Process and
Service to test the state of images. See the Testinfra
Docs for more information
on writing infrastructure tests.
img-proof currently passes the Pytest option -x
(stop on first
failure) through as --early-exit
. If there's an interest or need for
any other options/args please submit an issue to
Github.
CLI Overview
The CLI provides multiple subcommands to initiate image testing:
-
