  • Unified CLI now available for testing in RDO
    • Unified OpenStack Client command-line tool is now available for testing as python-openstackclient package at RDO Havana repository.

      OpenStack Client is on a mission to provide a single consistent CLI for interacting with OpenStack services. It's a thin wrapper to the stock python-*client modules that implement the actual REST API client actions. Although OpenStack Client is considered to be alpha quality as of 0.2, it already provides commands to interact with:

      • Keystone
      • Nova
      • Cinder
      • Glance

      Tips

      • With RDO Havana repository in place, install using yum install python-openstackclient
      • As with all clients, you need to supply your credentials. If you installed with packstack, . ~root/keystonerc_admin might do the trick.
      • Executable is called openstack
      • To get list of available commands, use openstack -h
      • To get usage of a specific command, use openstack help COMMAND

      Example usage

      $ openstack help image
      Command "image" matches:
        image delete
        image list
        image show
        image set
        image save
        image create
      
      
      $ openstack help image list
      usage: openstack image list [-h] [-f {csv,table}] [-c COLUMN]
                                  [--quote {all,minimal,none,nonnumeric}]
                                  [--page-size ]
      List available images
      [...]
      
      
      $ openstack image list

    • Great... thanks.

      Will the Havana unified client work with a Grizzly based cloud ?

    • Will the Havana unified client work with a Grizzly based cloud?

      Clients are supposed to be backward compatible but AFAIK it's not enforced in any way (yet).

      So it should.

      I originally posted this as a suggestion, but it's already there! If you want machine parse-able output, there are a variety of options you can use, such as -f csv. For example:

      $ openstack -q role list -f csv
      "ID","Name"
      "2bc174e4f66747e28d47381a1c38c0de","admin"
      "9fe2ff9ee4384b1894a90878d3e92bab","_member_"
      "a8cc78035b9e4a408554032677611643","Member"
