If Windows updates are being applied via a RUN command in a docker build, the build will not stop if there was a failure in postRunProcessing. To enable this behavior, we explicitly set the exit code of the container to a failure if postRunProcessing fails during servicing container step. For completeness, also avoid running servicing operation if the original exit code of the container is non-zero so that original failure exit code does not get overwritten. Signed-off-by: Stefan J.
