How to upload images to Openstack

Preparatory steps

  1. Install the openstack client, e.g. by running pip install python-openstackclient in a fresh virtualenv.
  2. Install gpg, and download signature keys for ubuntu When I was downloading the images following fingerprint was used: D2EB 4462 6FDD C30B 513D 5BB7 1A5D 6C4C 7DB8 7C81, with following short ID: 7DB87C81
  3. Download signing key: gpg --keyserver --recv-keys 7DB87C81

Download the images

  1. Download the images from: Example file to download:
  2. Download SHA256SUMS.txt and SHA256SUMS.gpg, verify these files gpg --verify SHA256SUMS.gpg SHA256SUMS.txt
  3. Verify downloaded image: sha256sum --check SHA256SUMS.txt

Upload the images

  1. Download the rc file: go to horizon console Access ans Security -> API Access -> Download RC File.
  2. Source openstack rc file.
  3. Upload the image:
    openstack image create --container-format=bare --disk-format=qcow2 \
        --file trusty-server-cloudimg-amd64-disk1.img trusty-14.04-unmodified-`date +%Y%m%d`

Note image format is qcow2 despite different image extension. It should be possible to use the glance client instead of the openstack command-line tool, but we had problems with glance ignoring the OpenStack region in the past.
