How do you update a QCOW2 image with the current patches? Or do you have to build a complete new image? I have a Heat Stack that fails because the updates are not current and it times out and says it failed. Or is there a way to re-run the heat stack on the updated image that was created by the initial heat stack?
Taking my image and running it then snapshot it after updating it then use
glance image-create --name "NAME_OF_IMAGE" --file PATH_TO_YOUR_SNAPSHOT --disk-format qcow2 --container-format bare --is-public True --progress
in my case I used the snapshots ID found here
cd /var/lib/glance/images/
then running the following in the same directory as the images
glance image-create --name "fedor202" --file 89ac2208-c9f2-42e8-93a0-17dde5536652 --disk-format qcow2 --container-format bare --is-public True --progress
gives me a yum updated image. Comes out a lot larger and I have not tested it against the heat stack yet but it should work right?
Hi tictoc,
Please note the linux images like centos, ubuntu are updated on weekly basis and you can download it from there and replace the existing ones. You can not update the images stored in glance you need to delete the old ones and create new ones. Apart from this if you are working on any other OS for which images are not available on the internet, you need to create / recreate images by yourself.

Thanks smaffulli for fixing my mucked up format! Also running a failed Instance build rebuilds the instance per the Heat Stack which allowed me to fix 2 of the 4 servers having issues. Not sure why they just would not get over the yum update hump with all of them running. Need cloud.init resources
