Project description

[![PyPI version](https://badge.fury.io/py/ironic-oneview-cli.svg)](https://badge.fury.io/py/ironic-oneview-cli) [![Build Status](https://travis-ci.org/HewlettPackard/ironic-oneview-cli.svg?branch=master)](https://travis-ci.org/HewlettPackard/ironic-oneview-cli) [![Coverage Status](https://codecov.io/gh/HewlettPackard/ironic-oneview-cli/branch/master/graphs/badge.svg)](https://codecov.io/gh/HewlettPackard/ironic-oneview-cli)

Ironic-OneView CLI

Overview

Ironic-OneView CLI is a command line interface tool for easing the use of the OneView Drivers for Ironic. It allows the user to easily manage:

  • Ironic nodes compatible with OneView Server Hardware objects;
  • Nova flavors matching available Ironic nodes that use OneView drivers;
  • Ironic ports mapping Server Hardware ports.

> note > > This tool works with OpenStack Identity API v2.0 and v3.

> note > > This tool works with OpenStack Ironic API microversion ‘1.31’.

For more information on HPE OneView entities, see [here](https://www.hpe.com/us/en/integrated-systems/software.html).

Installation

To install Ironic-OneView CLI from PyPI, use the following command:

$ pip install ironic-oneview-cli

> note > > Ocata/Newton users, we recommend using version 0.6.0

Configuration

Ironic-Oneview CLI uses credentials loaded into environment variables by the OpenStack RC file (downloaded from OpenStack Horizon), and the Ironic OneView CLI RC file, which sample file can be generated using the following genrc subcommand:

$ ironic-oneview genrc > ironic-oneviewrc.sh

Once the ironic-oneviewrc.sh is populated with OneView credentials using any text editor, it can be loaded by running the following:

$ source ironic-oneviewrc.sh

Credentials can be passed alternatively as command line parameters. A help message informing of which parameters should be used is shown by running the command the following:

$ ironic-oneview help

For more information how to obtain and load the OpenStack RC file, see [here](http://docs.openstack.org/user-guide/common/cli_set_environment_variables_using_openstack_rc.html).

Usage

Once the necessary environment variables and command line parameters are set, Ironic OneView CLI is ready to be used. The current version of Ironic-OneView CLI provides the following interactive subcommands:

<table> <col width=”23%” /> <col width=”76%” /> <tbody> <tr class=”odd”> <td align=”left”><blockquote> <p>node-create</p> </blockquote></td> <td align=”left”>Creates Ironic nodes based on available HPE OneView Server Hardware.</td> </tr> <tr class=”even”> <td align=”left”><blockquote> <p>flavor-create</p> </blockquote></td> <td align=”left”>Creates Nova flavors based on available Ironic nodes.</td> </tr> <tr class=”odd”> <td align=”left”><blockquote> <p>port-create</p> </blockquote></td> <td align=”left”>Creates a Ironic Port based on available Ironic nodes.</td> </tr> <tr class=”even”> <td align=”left”><blockquote> <p>server-profile-template-list</p> </blockquote></td> <td align=”left”>Lists HPE OneView Server Profile Templates.</td> </tr> <tr class=”odd”> <td align=”left”><blockquote> <p>server-hardware-list</p> </blockquote></td> <td align=”left”>Lists HPE OneView Server Hardware.</td> </tr> <tr class=”even”> <td align=”left”><blockquote> <p>node-delete</p> </blockquote></td> <td align=”left”>Deletes multiple Ironic nodes.</td> </tr> <tr class=”odd”> <td align=”left”><blockquote> <p>genrc</p> </blockquote></td> <td align=”left”>Generates a sample Ironic-OneView CLI RC file.</td> </tr> <tr class=”even”> <td align=”left”><blockquote> <p>help</p> </blockquote></td> <td align=”left”>Displays help about this program or one of its subcommands.</td> </tr> </tbody> </table>

Any ironic-oneview-cli subcommand can be run in debugging mode with the –debug parameter, as in the following command:

$ ironic-oneview –debug node-create

Features

### Node creation

To create Ironic nodes based on available HPE OneView Server Hardware objects, use the following command:

$ ironic-oneview node-create

The tool retrieves all server profile templates previously created in OneView. It builds a list with the Name, Enclosure Group Name and Server Hardware Type Name (as shown in the table), and assigns an id that should be used by the administrator to select which Server Profile Template should be used for node creation:

Id Name Enclosure Group Name Server Hardware Type Name
1 2 template-dcs-virt-enc3 template-dcs-virt-enc4 virt-enclosure-group virt-enclosure-group BL460c Gen8 3 BL660c Gen9 1

Once the user has chosen a valid Server Profile Template, the tool lists the available Server Hardware matching it as shown in the following table:

Id Name CPUs Memory MB Local GB Enclosure Group Name Server Hardware Type Name
1 2 VIRT-enl, bay 5 VIRT-enl, bay 8 8 8 32768 32768 120 120 virt-enclosure-group virt-enclosure-group BL460c Gen8 3 BL460c Gen8 3

Notice that multiple Ironic nodes can be created at once. That can be achieved, by selecting multiple Server Hardware IDs separated by blank spaces. The created Ironic nodes will be in the enroll provisioning state.

This command also creates an Ironic port to be used by the node, the port is created in the same way as the port-create command (see below) with the parameter –mac also optional.

> note > > If os_inspection_enabled = True, the created node will not have the hardware properties (cpus, memory_mb, local_gb, cpu_arch) set in the node properties. This will be discovered during the Ironic Hardware Inspection.

Alternatively, the Server Profile Template and Server Hardware can be specified using the parameters –server-profile-template and –server-hardware-uuid respectively, as shown in the following command:

$ ironic-oneview node-create [–server-profile-template | -t <spt>] [–server-hardware-uuid | -s <server_hardware>]

A collection of nodes sharing the same Server Profile Template can be set up in a batch by using the following command:

$ ironic-oneview node-create [–number | -n <number>]

> note > > You can use both arguments at once.

In order to enable Networking OneView ML2 Driver, the following command to create a node with this information set to its driver_info field:

$ ironic-oneview node-create –use-oneview-ml2-driver

For more information on Networking OneView ML2 Driver, see [here](https://github.com/HewlettPackard/ironic-driver-oneview/tree/master/networking-oneview).

With the Driver composition reform, the default behavior is to create a node using a hardware type. With this feature, specific hardware type compatible interfaces can be dynamically set to the node, such as: OpenStack Power Interface, OpenStack Management Interface, OpenStack Inspect Interface, OpenStack Deploy Interface. Use the following command to create a node with this hardware type and interfaces:

$ ironic-oneview node-create –os-driver <hardware_type> –os-power-interface <power_interface>
–os-management-interface <management_interface> –os-inspect-interface <inspect_interface> –os-deploy-interface <deploy_interface>

If you want to create the node using the classic driver, use the following command:

$ ironic-oneview node-create –classic

For more information on the Driver composition reform, see [here](https://specs.openstack.org/openstack/ironic-specs/specs/approved/driver-composition-reform.html).

To list all nodes in Ironic, use the following command:

$ openstack baremetal node list

For more information about the created Ironic node, use the following command:

$ openstack baremetal node show <node>

### Flavor creation

In order to launch bare metal instances, the user needs to specify a flavor compatible with an available Ironic Node, which maps directly to an available Server Hardware. The following interactive command can be used to create Nova flavors:

$ ironic-oneview flavor-create

The tool will prompt with a list of possible new flavors, according to the configuration of enrolled Ironic nodes:

Id CPUs Disk GB Memory MB Server Profile Template Server Hardware Type Enclosure Group Name
1 8 120 8192 second-virt-server-profile-template BL460c Gen9 1 virtual-enclosure-group

After choosing a valid configuration, the user can optionally specify a name for the new flavor. If left blank, a default name will be used. Additional information from Server Hardware Type, Enclosure Group and Server Profile Template is automatically added by default to the flavor metadata. Use Horizon to delete the Enclosure Group info, for example, so that a flavor matches Server Hardware in all available enclosures.

Alternatively, you can set a Ironic node, and optionally flavor name through the command:

$ ironic-oneview flavor-create [–node <node>] [–name <name>]

To list all flavors in Nova, use the command:

$ openstack flavor list

For more information about the created Nova flavor, use the command:

$ openstack flavor show <flavor>

### Port creation

Creates a port for an existing Ironic node. The following interactive command can be used to create Ironic ports:

$ ironic-oneview port-create [–mac | -m <mac>] <node>

In the case when the user does not specify a port, the result will be an Ironic port for the first -a available port at the Server Hardware used by ironic-node.

To list all ports in Ironic, use the command:

$ openstack baremetal port list

For more information about the created Ironic port, use the following command:

$ openstack baremetal port show <port>

### Server Profile Template List

The tool offers a command to list Server Profile Templates. For that use the following command:

$ ironic-oneview server-profile-template-list

### Server Hardware List

The tool offers a command to list Server Hardware compatible with a specific Server Profile Template. For that use the following command:

$ ironic-oneview server-hardware-list

### Node delete

The tool also offers the option to delete a specific number of Ironic nodes. For that use the following command:

$ ironic-oneview node-delete –number <number>

To delete all Ironic nodes, use the following command:

$ ironic-oneview node-delete –all
