glance-proxy

Proxy to provide image data from Openstack glance via HTTP, using an S3-like temporary store to support Range requests.

Main use case is to allow conversion of raw disk images stored in glance using qemu-img convert on a system that does not have enough local disk space to accomodate the conversion.

The server requires environment variables be set to provide login details for both Openstack and Minio (S3 client).

Run the server on localhost:

rt OS_AUTH_URL=https://os.example.com:5001/v2.0
rt OS_USERNAME=example-user
rt OS_PASSWORD=XXXXXXXXXXXXXXXX
rt OS_TENANT_NAME=example-tenant
rt MINIO_ENDPOINT=s3.amazonaws.com
rt MINIO_ACCESS_KEY_ID=XXXXXXXXXXXXXXXXXXXX
rt MINIO_SECRET_ACCESS_KEY=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
ce-proxy -minio-bucket openstack-images -minio-prefix tmp

Example invocation of qemu-img:

-img convert -O qcow2 --image-opts 'driver=http,timeout=900,url=http://127.0.0.1:8080/id/e50aefed-28a1-4118-bca5-32784626d51d' e50aefed-28a1-4118-bca5-32784626d51d.qcow2
