Abhishek, Thansk for your answer, I tried both CLIs (Train release) and the issue still the same. Paste of the "curl" command: http://paste.openstack.org/show/790197/ Result of the "md5sum" on the file created by the "curl": $ md5sum /tmp/kernel.glance c3726de8e03158305453f328d85e9957 /tmp/kernel.glance As Mark and Radoslaw, I'm quite surprised about OSC been deprecated. Do you have any release note about this? Thanks for your help.

Hi Gaëtan,
Glance team doesn't recommend to use OSC anymore. I will recommend you to check the same behaviour using python-glanceclient.
That's not cool - everyone has switched to OSC. It's also the first time I've heard of it.
Thanks & Best Regards,

Hey Monty,
If I download the image via the CLI, the checksum of the file matches the checksum from the image details. If I download the image via "curl", the "Content-Md5" header matches the image details but the file checksum doesn't.
The files have the same size, this is really weird.
WOW.
I still don’t know the issue - but my unfounded hunch is that the curl command is likely not doing something it should be. If OSC is producing a file that matches the image details, that seems like the right choice for now.
Seriously fascinating though.

During the image creation a checksum is computed to check the image integrity, using the "openstack" CLI match the checksum generated but when "curl" is used by following the API documentation[1] the checksum change at every "download". Any idea? That seems strange. I don’t know off the top of my head. I do know Artem has patches up to switch OSC to using SDK for image operations. https://review.opendev.org/#/c/699416/ That said, I’d still expect current OSC checksums to be solid. Perhaps there is some filtering/processing being done cloud-side in your glance? If you download the image to a file and run a checksum on it - does it match the checksum given by OSC on upload? Or the checksum given by glance API on download? Thanks, Gaëtan [1] https://docs.openstack.org/api-ref/image/v2/index.html?expanded=download-bin...
