if you specify: --glance_host=<ip of="" glance=""> --image_service=nova.image.glance.GlanceImageService in your flagfile, the euca commands, will end up storing the final decrypted image and metadata in whatever backend you have glance configured to use.

Dennis DeMarco is still having a problem: I understand a bit better now. Thank you. So in order for euca- bundle/etc to work both glance and nova-object store need to be running because those tools need a S3 service.

Does the image upload get placed into glance's backend? When I tried running both glance and nova-object, the location of the image never referenced a swift URL (glance details).

So images what were uploaded using glance-add/upload were in swift while images using euca toolset were referenced local. Is there a configuration setting for nova-object that I missed?

one typo in my description above. this line:

• uploads manifest and xml to an s3 bucket

should say:

• uploads manifest.xml and part files to an s3 bucket

I have the same problem. I can add image through glance, but i can't use euca-upload-bundle, uec-publish-tarball to upload. Below is my error message.

"uec-publish-tarball" error message:

Hi Dennis,

I'm trying to do the same thing right now. As I understand it, if you want to use uec-publish-tarball or the euca-bundle-* commands then you need to run nova-objectstore. Those commands require an S3 API and nova-objectstore is the service that provides it.

However, when I run nova-objectstore and do an upload the image doesn't get stored in Swift. Instead the parts get stored in the usual image directory /var/lib/nova/buckets/ dir.

My relevant nova.conf config is:

--s3_host=127.0.0.1 --glance_host=127.0.0.1 --image_service=nova.image.glance.GlanceImageService

(I'm keeping everything on one machine for the moment while I'm testing, hence the 127 address)

Of course I haven't even been able to store my images in Swift using glance-add (see https://answers.launchpad.net/glance/+question/154253 (https://answers.launchpad.net/glance/...) ) so I might have something else misconfigured.

Would you be willing to share your glance config so I can compare it with my config? If I can get glance-add working, I'll be able to move on to getting the uec-publish-tarball and euca-bundle-* commands working with Glance/Swift and can try to continue to help.

It is my understanding nova-object should not run if you are running with glance. It should all go through glance. I just do not think the API is yet compatible with euca-bundle/uec yet. I'm running swift object store to store all my images and nova-object is local machine only storage.

I want to clarify something here. Nova-objectstore exists only to support euca-upload-bundle and to make euca-register work properly. It works fine with glance image service and local image service.

Nova-objectstore is just a a very simple bucket service (replicates s3 api).

There seems to be quite a bit of confusion on this point, so let me describe how the AWS image registration works by describing what each of the euca commands does.

euca-bundle-vol/euca-bundle-image: * compresses the volume/image * encrypts the compressed file * breaks the encrypted file into 10 mb chunks * creates a manifest.xml file with metadata about the image and all of the chunks

euca-upload-bundle: * uploads manifest and xml to an s3 bucket

euca-register * grabs the manifest from an s3 bucket * downloads all of the part files * combines the part files into one file * decrypts the file * decompresses the file * extracts metadata from the manifest * makes the image available (this involves uploading the decompressed file into the image service along with image metadata)

As you can see, the AWS model for uploading images requires an S3 service to make uploading work. Therefore, to run these commands, you need to have some sort of S3 service. Nova-objectstore is just an ultra-simple s3 service to support this particular set of commands.
