▪ CloudShell version 9.3 and above

Note: If your CloudShell version does not support this shell, you should consider upgrading to a later version of CloudShell or contact customer support.

Data Model

The shell's data model includes all shell metadata, families, and attributes.

OpenStack Cloud Provider Shell 2G Attributes

The attribute names and types are listed in the following section of the Cloud Provider Shell Standard:

Common Cloud Provider Attributes

The following table describes attributes that are unique to this shell and are not documented in the Shell Standard:

Attribute Name Data Type Description
Controller URL String OpenStack Keystone Controller URL endpoint address. For example: http://controler:5000/v3.
OpenStack Domain Name String OpenStack domain to use.
OpenStack Project Name String OpenStack project in which CloudShell will create the instances.
OpenStack Management Network ID String UUID of the manually created CloudShell management network (for assistance identifying your management network, contact your OpenStack admin). This network will be used to configure the communication between the Sandbox instances and the CloudShell components. For example: c14241d2-376c-4fb3-8d1e-61f5c1408448. Note: The UUID can be found in the Horizon user interface.
Password Password OpenStack user's password
User String OpenStack user on the OpenStack server
OpenStack Reserved Networks string Comma separated list (,) of reserved networks. vNICs configured to these networks will not be used for instance connectivity. Note: Ideally, one of the following three ranges should be free: 10.0.0.0/8, 172.16.0.0/16, 192.168.0.0/16
VLAN Type String The VLAN technology to use for connectivity to/from this cloud provider. Options are VLAN and VXLAN.
Floating IP Subnet ID String UUID of the external network subnet that will allocate floating IDs to the OpenStack instances, to allow external connectivity into those instances. For assistance identifying your Floating IP network, contact your OpenStack admin. For additional details, see OpenStack Configuration Requirements.
OpenStack Physical Interface Name String (Not required if you set the VLAN Type attribute to VXLAN) The physical interface mapping name to use when configuring OpenStack connectivity. The physical interface can be found under the connectivity provider configuration in your OpenStack plugin's agent file. For example: For Linux Bridge plugin, use /etc/neutron/plugins/ml2/linuxbridge_agent.ini file > [linux_bridge] configuration section > physical_interface_mappings attribute. For example: physical_interface_mappings = public:em1,office:p1p2,quali:em2. And for Open vSwitch plugin, /etc/neutron/plugins/ml2/openvswitch_agent.ini file > [ovs] configuration section > bridge_mappings attribute. For example: bridge_mappings = public:br-vlan.
Execution Server Selector String (Optional) This attribute points to a pre-defined group of execution servers (grouped by a common Execution Server Selector value). This attribute is typically used for different sites or domains. For additional information on managing App deployments per domains, see Managing Private Cloud Apps in Domains.

Automation

This section describes the automation (driver) associated with the data model. The shell’s driver is provided as part of the shell package. There are two types of automation processes, Autoload and Resource. Autoload is executed when creating the resource in the Inventory dashboard.

For detailed information on each available commands, see the following section of the Cloud Provider Standard:

Common Cloud Provider Commands

OpenStack Integration Process

In order to integrate CloudShell with OpenStack, you need to first prepare OpenStack with the required user permissions, quotas, networks etc. Then, create an OpenStack cloud provider resource and App templates which include the definition of the VMs, images and configuration management to be performed on the deployed VMs. For details, see CloudShell Help's Azure Integration chapter.

Downloading the Shell

The OpenStack Cloud Provider Shell 2G shell is available from the Quali Community Integrations page.

  2. In CloudShell Portal, as Global administrator, open the Manage – Shells page.

  3. Click Import.

  4. In the dialog box, navigate to the shell's zip package, select it and click Open.

    The shell is displayed in the Shells page and can be used by domain administrators in all CloudShell domains to create new inventory resources, as explained in Adding Inventory Resources.

Offline installation of a shell

Note: Offline installation instructions are relevant only if CloudShell Execution Server has no access to PyPi. You can skip this section if your execution server has access to PyPi. For additional information, see the online help topic on offline dependencies.

In offline mode, import the shell into CloudShell and place any dependencies in the appropriate dependencies folder. The dependencies folder may differ, depending on the CloudShell version you are using:

Adding shell and script packages to the local PyPi Server repository

If your Quali Server and/or execution servers work offline, you will need to copy all required Python packages, including the out-of-the-box ones, to the PyPi Server's repository on the Quali Server computer (by default C:\Program Files (x86)\QualiSystems\CloudShell\Server\Config\Pypi Server Repository).

For more information, see Configuring CloudShell to Execute Python Commands in Offline Mode.

To add Python packages to the local PyPi Server repository:

  1. If you haven't created and configured the local PyPi Server repository to work with the execution server, perform the steps in Add Python packages to the local PyPi Server repository (offline mode).

  2. For each shell or script you add into CloudShell, do one of the following (from an online computer):

    • Connect to the Internet and download each dependency specified in the requirements.txt file with the following command: pip download -r requirements.txt. The shell or script's requirements are downloaded as zip files.

    • In the Quali Community's Integrations page, locate the shell and click the shell's Download link. In the page that is displayed, from the Downloads area, extract the dependencies package zip file.

  3. Place these zip files in the local PyPi Server repository.

Configuring a new resource

This section explains how to create a new resource from the shell.

In CloudShell, the component that models the device is called a resource. It is based on the shell that models the device and allows the CloudShell user and API to remotely control the device from CloudShell.

You can also modify existing resources, see Managing Resources in the Inventory.

To create a resource for the device:

  1. In the CloudShell Portal, in the Inventory dashboard, click Add New. Image

  2. From the list, select OpenStack Cloud Provider Shell 2G.

  3. Click Create.

  4. In the Resource dialog box, enter the following mandatory attributes with data from step 1:

    • Controller URL - OpenStack Keystone Controller URL endpoint address. For example: http://controler:5000/v3.

    • OpenStack Domain Name - OpenStack domain to use.

    • OpenStack Project Name - OpenStack project in which CloudShell will create the instances.

    • OpenStack Management Network ID - UUID of the manually created CloudShell management network (for assistance identifying your management network, contact your OpenStack admin). This network will be used to configure the communication between the Sandbox instances and the CloudShell components. For example: c14241d2-376c-4fb3-8d1e-61f5c1408448
      Note: The UUID can be found in the Horizon user interface.

    • Password - OpenStack user's password

    • User - OpenStack user on the OpenStack server

    • OpenStack Reserved Networks - Comma separated list (,) of reserved networks. vNICs configured to these networks will not be used for instance connectivity.
      Note: Ideally, one of the following three ranges should be free: 10.0.0.0/8, 172.16.0.0/16, 192.168.0.0/16

    • VLAN Type - The VLAN technology to use for connectivity to/from this cloud provider. Options are VLAN and VXLAN.

    • Floating IP Subnet ID - UUID of the external network subnet that will allocate floating IDs to the OpenStack instances, to allow external connectivity into those instances. For assistance identifying your Floating IP network, contact your OpenStack admin. For additional details, see OpenStack Configuration Requirements.

    • OpenStack Physical Interface Name - (Not required if you set the VLAN Type attribute to VXLAN) The physical interface mapping name to use when configuring OpenStack connectivity. The physical interface can be found under the connectivity provider configuration in your OpenStack plugin's agent file. For example:

      • For Linux Bridge plugin: /etc/neutron/plugins/ml2/linuxbridge_agent.ini file > [linux_bridge] configuration section > physical_interface_mappings attribute. For example: physical_interface_mappings = public:em1,office:p1p2,quali:em2.
      • For Open vSwitch plugin: /etc/neutron/plugins/ml2/openvswitch_agent.ini file > [ovs] configuration section > bridge_mappings attribute. For example: bridge_mappings = public:br-vlan.

    • Execution Server Selector - (Optional) This attribute points to a pre-defined group of execution servers (grouped by a common Execution Server Selector value). This attribute is typically used for different sites or domains. For additional information on managing App deployments per domains, see Managing Private Cloud Apps in Domains.

  5. Click Continue.

CloudShell validates provided settings and creates the new resource.

OpenStack Cloud Provider Shell 2G requires you to set up an OpenStack cloud provider resource and also create an appropriate App template, which would be deployed as part of the sandbox reservation. For details, see OpenStack Integration

Updating Python Dependencies for Shells

This section explains how to update your Python dependencies folder. This is required when you upgrade a shell that uses new/updated dependencies. It applies to both online and offline dependencies.

Updating offline Python dependencies

To update offline Python dependencies:

  1. Download the latest Python dependencies package zip file locally.

  2. Extract the zip file to the suitable offline package folder(s).

  3. Terminate the shell’s instance, as explained here.

Updating online Python dependencies

In online mode, the execution server automatically downloads and extracts the appropriate dependencies file to the online Python dependencies repository every time a new instance of the driver or script is created.

To update online Python dependencies:

  • If there is a live instance of the shell's driver or script, terminate the shell’s instance, as explained here. If an instance does not exist, the execution server will download the Python dependencies the next time a command of the driver or script runs.

Typical Workflows

Connecting OpenStack App to an existing network

This capability is supported for Apps based on OpenStack 2nd Gen shell version 1.2.0 and up. This section explains how to enable CloudShell to connect an OpenStack App to an existing network. This capability requires editing the VLAN Auto / VLAN Manual service models in Resource Manager Client.

Prerequisites:

  • OpenStack network that has a subnet

To allow connecting to an existing VLAN network:

  1. In Resource Manager Client, open the Attributes explorer.
  2. Edit the Virtual Network attribute.
  3. Unselect the Read-only checkbox and click OK and save.
  4. Open the Resource Families explorer and expand the Virtual Network family.
  5. Click the appropriate service model (VLAN Auto / VLAN Manual).
  6. From the model's Attributes tab, select Virtual Network and click Edit Rules.
  7. Select User input and click OK and save.
  8. In the blueprint, add the VLAN service and specify a network name or ID in the Virtual Network field. Make sure to specify a value in the VLAN ID field - this will be ignored but it must have a value as it's a system mandatory attribute.
  9. Click Add.

Specify Subnet CIDR for OpenStack VLAN service

This capability is supported for Apps based on OpenStack 2nd Gen shell version 1.2.0 and up. This capability requires editing the VLAN Auto / VLAN Manual service models in Resource Manager Client.
