Description Michele Baldessari 2020-11-12 18:14:37 UTC 
Description of problem:
Via https://review.opendev.org/#/c/752937/ 
(https://bugzilla.redhat.com/show_bug.cgi?id=1881476) we added the following code:
       if container_image:
            image_id_str = self.runner.inspect(
                container_image, "{{index .Id}}", o_type='image')
            if str(image_id_str).strip() != inspect_info.get('Image'):
                self.log.debug("Deleting container (image updated): "
                               "%s" % container)
                self.runner.remove_container(container)
                return True

This code works fine in docker:
[root@controller-0 ~]# docker inspect --type image --format '{{index .Id}}' f6ec0f326154     
sha256:f6ec0f326154a80b6844a03c2de2904bbbefea6cdf87acb606ff869ace1a8dd4                      
                     
But is problematic in podman (both on 1.6.4 and 2.1.1 versions):
[root@controller-0 ~]# podman inspect --type image --format '{{index .Id}}' undercloud-0.ctlplane.redhat.local:8787/rh-osbs/rhosp16-openstack-cinder-volume:16.2_20201110.2-hotfixupdate2
ERRO[0000] Error printing inspect output: Template parsing error: template: image:1:8: executing "image" at <.Id>: can't evaluate field Id in type *entities.ImageInspectReport    

This has the side-effect of restarting all containers at each identical redeploy.      

We can just drop the 'index' in the query since it works in both docker and podman:
[root@controller-0 ~]# docker inspect --type image --format '{{.Id}}' f6ec0f326154           
sha256:f6ec0f326154a80b6844a03c2de2904bbbefea6cdf87acb606ff869ace1a8dd4 

[root@controller-0 ~]# podman inspect --type image --format '{{.Id}}' 5093412f3a08
