Prior this commit the ami images were tested locally using qemu. This does
not reflect at all how they're used in practice. This commit introduces
the support for running them in the actual AWS. Yay!
The structure of code reflects that we want to switch to osbuild-composer
to build the images soon.
Build constraints must be added to every file. We only want to build
this package when the `integration` tag is set.
Without this, every build prints this warning:
# github.com/osbuild/osbuild-composer/cmd/osbuild-image-tests
runtime.main_main·f: function main is undeclared in the main package
When using %#v instead of %v, printing an error gives a slightly more
informative error message, therefore this commit switches to %#v in all
error prints.
This commit makes the osbuild-image-tests binary doing the same set of tests
like the old test/run script.
Changes from test/run:
- qemu/nspawn are now killed gracefully. Firstly, SIGTERM is sent.
If the process doesn't exit till the timeout, SIGKILL is sent.
I changed this because nspawn leaves some artifacts behind when killed
by SIGKILL.
- the unsharing of network namespace now works differently because of
systemd issue #15079
