Verify operation

Verify operation of the Image service using CirrOS, a small Linux image that helps you test your OpenStack deployment.

For more information about how to download and build images, see OpenStack Virtual Machine Image Guide. For information about how to manage images, see the OpenStack End User Guide.

Note

Perform these commands on the controller node.

  1. Source the admin credentials to gain access to admin-only CLI commands:

    $ . admin-openrc
    
  2. Download the source image:

    $ wget http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img
    

    Note

    Install wget if your distribution does not include it.

  3. Upload the image to the Image service using the QCOW2 disk format, bare container format, and public visibility so all projects can access it:

    $ openstack image create "cirros" \
      --file cirros-0.4.0-x86_64-disk.img \
      --disk-format qcow2 --container-format bare \
      --public

    For information about the openstack image create parameters, see Create or update an image (glance) in the OpenStack User Guide.

    For information about disk and container formats for images, see Disk and container formats for images in the OpenStack Virtual Machine Image Guide.

    Note

    OpenStack generates IDs dynamically, so you will see different values in the example command output.

  4. Confirm upload of the image and validate attributes:

    $ openstack image list
