Glance

Using Swift as a Glance backend

Asked by Everett Toews

I'm trying to use Swift as a Glance backend but I'm running into errors when I try to add an image with glance add.

root@i-00000c7f:~# glance add --verbose name="ubuntu-10-10-server" is_public="True" < ubuntu-10.10-server-uec-amd64.tar.gz
Failed to add image. Got error:
400 Bad Request

The server could not comply with the request since it is either malformed or otherwise incorrect.

 Error uploading image: Auth GET failed: https://127.0.0.1:8080/auth/v1.0/ 401 Unauthorized
Completed in 2.0094 sec.

I'm using Glance version: 2011.2-0ubuntu1

My relevant config in glance.conf

default_store = swift
swift_store_auth_address = https://127.0.0.1:8080/auth/v1.0/
swift_store_user = root
swift_store_key = testpass
swift_store_container = glance
swift_store_create_container_on_put = True

I'm fairly confident Swift is up and running as it should be since I can do the following.

swauth-prep -A https://127.0.0.1:8080/auth/ -K admin_key
swauth-add-user -A https://127.0.0.1:8080/auth/ -K admin_key -a system root testpass

root@i-00000c7f:~# st -A https://127.0.0.1:8080/auth/v1.0/ -U system:root -K testpass -v post glance

root@i-00000c7f:~# st -A https://127.0.0.1:8080/auth/v1.0/ -U system:root -K testpass -v upload glance ubuntu-10.10-server-uec-amd64.tar.gz
ubuntu-10.10-server-uec-amd64.tar.gz

root@i-00000c7f:~# st -A https://127.0.0.1:8080/auth/v1.0/ -U system:root -K testpass -v list glance
ubuntu-10.10-server-uec-amd64.tar.gz

root@i-00000c7f:~# st -A https://127.0.0.1:8080/auth/v1.0/ -U system:root -K testpass -v delete glance ubuntu-10.10-server-uec-amd64.tar.gz
ubuntu-10.10-server-uec-amd64.tar.gz

root@i-00000c7f:~# st -A https://127.0.0.1:8080/auth/v1.0/ -U system:root -K testpass -v list glance

Anyone have any thoughts as to what the problem could be?

Thanks,
Everett

Everett,

Barton just found me in the lobby... I haven't been getting any notifications about Glance Questions :( So, sorry about not responding until now.

I will work with a Swift dev to figure out what's going on here. AFAICT, your glance.conf is correct. Though, do you have logging enabled? Getting some log output with debug=True would be good...

Hi Jay,

I just set debug=True and tried again

root@i-00000c7f:~# glance add --verbose
name="ubuntu-10-10-server-glance-add" is_public="True" <
ubuntu-10.10-server-uec-amd64.tar.gz

The results are here.

Hi,

The parameter 'swift_store_user' should not be set to 'system:root' instead of 'root' ?

Yep. That was the secret sauce. Now I can see the file saved in Swift.

root@i-00000c7f:~# st -A https://127.0.0.1:8080/auth/v1.0/ -U system:root -K testpass -v list glance
10

To be totally paranoid I double checked that the Glance CLI and Swift st CLI are reporting the same size

Do you met problems to delete images in Glance repository with Swift backend ?

Hi Édouard,

Actually yes, I ran into that problem too. Thanks for posting another
question about it. I'm tracking it now too.

Everett and Edouard,

Hey, we're working on this. In the meantime, the fix would be to remove the https:// prefix from your swift_store_auth_address configuration option..

Hi Jay,

I try to remove the 'https://' prefix in 'swift_store_auth_address' option but the bug persists.

Chears,
Édouard.

Hi Edouard,

For the existing images in the registry database, you will want to execute the following:

UPDATE images SET location = REPLACE(location, "https://", "")
WHERE location LIKE 'swift%';

The above should work for MySQL, SQLIte and PostgreSQL registry databases.

The eventual bug fix will include the above as a migration file, FYI...

Cheers,
jay
