Mark Goddard 0bd26cc47e Fix AttributeError in negotiate_version
Seen in kolla-ansible CI, if ironic inspector starts up before ironic
API is properly up, we see the following error:

The PXE filter DnsmasqFilter, state=initialized encountered an
exception: StrictVersion instance has no attribute 'version'; resetting
the filter: AttributeError: StrictVersion instance has no attribute
'version'

Example: http://paste.openstack.org/show/756342/

The usual cause of this error is when StrictVersion is initialised with
a version of None. This suggests to me that max_ver is None.

This leads to an exception being raised that circumvents the client's
retry mechanisms.

In the particular case of kolla-ansible CI, Ironic API is behind a load
balancer, and all backends are down resulting in a 503. The lack of a
retry caused ironic inspector to fail on startup.

This patch catches the case where we get a 4xx or 5xx return code when
checking the version, and raises an error that works with the client's
retry mechanisms.

Python bindings for the Ironic API

Overview

This is a client for the OpenStack Bare Metal API. It provides:

  • a Python API: the ironicclient module, and
  • two command-line interfaces: openstack baremetal and ironic (deprecated, please use openstack baremetal).

Development takes place via the usual OpenStack processes as outlined in the developer guide. The master repository is on git.openstack.org.

python-ironicclient is licensed under the Apache License, Version 2.0, like the rest of OpenStack.

Python API

Quick-start Example:

>>> from ironicclient import client
>>>
>>> kwargs = {'os_auth_token': '3bcc3d3a03f44e3d8377f9247b0ad155',
>>>           'ironic_url': 'http://ironic.example.org:6385/'}
>>> ironic = client.get_client(1, **kwargs)

openstack baremetal CLI

The openstack baremetal command line interface is available when the bare metal plugin (included in this package) is used with the OpenStackClient.

There are two ways to install the OpenStackClient (python-openstackclient) package:

  • along with this python-ironicclient package:

    # pip install python-ironicclient[cli]
  • directly:

    # pip install python-openstackclient

An example of creating a basic node with the ipmi driver:

$ openstack baremetal node create --driver ipmi

An example of creating a port on a node:

$ openstack baremetal port create --node <UUID> AA:BB:CC:DD:EE:FF

An example of updating driver properties for a node:

$ openstack baremetal node set --driver-info ipmi_address=<IPaddress> <UUID or name>

For more information about the openstack baremetal command and the subcommands available, run:

$ openstack help baremetal

ironic CLI (deprecated)

This is deprecated and will be removed in the S* release. Please use the openstack baremetal CLI instead.

This package will install the ironic command line interface that you can use to interact with the ironic API.

In order to use the ironic CLI you'll need to provide your OpenStack tenant, username, password and authentication endpoint. You can do this with the --os-tenant-name, --os-username, --os-password and --os-auth-url parameters, though it may be easier to set them as environment variables:

$ export OS_PROJECT_NAME=project
$ export OS_USERNAME=user
$ export OS_PASSWORD=pass
$ export OS_AUTH_URL=http://auth.example.com:5000/v2.0

To use a specific Ironic API endpoint:

$ export IRONIC_URL=http://ironic.example.com:6385

An example of creating a basic node with the ipmi driver:

$ ironic node-create -d ipmi

An example of creating a port on a node:

$ ironic port-create -a AA:BB:CC:DD:EE:FF -n nodeUUID

An example of updating driver properties for a node:

$ ironic node-update nodeUUID add driver_info/ipmi_address=<IPaddress>
$ ironic node-update nodeUUID add driver_info/ipmi_username=<username>
$ ironic node-update nodeUUID add driver_info/ipmi_password=<password>

For more information about the ironic command and the subcommands available, run:

$ ironic help
