h2. Objective Users can upload files. Files can be used as images for VMs, if they are in the qcow2 format. h2. How it works * Files are uploaded to a specific VM (likely files.datacenterlight.ch) * Users can use the ucloud-cli to convert a file to an image h2. CLI * ucloud image-create-from-file --uuid $UUID --name <name-of-the-image> --image-store <name> [--desc "optional description"] [--public] ** if --public is passed, the image is public ** do not implement --public before v2 ** for --public we need to clarify how is paying for the storage ** Need to specify the name of the image store; OR we use the UUID (persisten!) of the image store * ucloud image-set-permission [--public|--private] ** makes image public or private ** do not implement before v2 h3. API The API modifies entries in etcd as follows: * Finds the file in etcd ** if it does not exist -> error out ** Only accept "sane" filenames (i.e. no .. and funky stuff) * Creates an image entry below /v1/image/$UUID ** maybe the same UUID as the file OR a random UUID - to be discussed in ucloud channel ** JSON: set status on create to "TO_BE_CREATED", needs to include "owner" field h3. Cron job on files.datacenterlight.ch * Scans all entries in /v1/image * If there is a json with TO_BE_CREATED ** Look for the filename below basepath/$owner/$filename ** If it is not there, error out * If image is found ** Verify that it is qcow2 format (file or qemu-img) ** Convert it to raw and import it into ceph *** qemu-img convert ... | rbd import ... -> ping @llnu for a test ceph cluster to try this out
