Overview

A shell integrates a device model, application or other technology with CloudShell. A shell consists of a data model that defines how the device and its properties are modeled in CloudShell, along with automation that enables interaction with the device via CloudShell.

Networking Shells

CloudShell's networking shells provide L2 or L3 connectivity between resources and/or Apps.

Juniper JunOS Switch 2G Shell

The Juniper JunOS Switch shell provides you with connectivity and management capabilities such as device structure discovery and power management for the Juniper JunOS Switch.

For more information on the Juniper JunOS Switch, see the official Juniper JunOS product documentation.

There are two types of automation processes, Autoload and Resource. Autoload is executed when creating the resource in the Inventory dashboard, while resource commands are run in the sandbox.

The following resource commands are available on the Juniper JunOS Switch:

  • Health Check
  • Run Custom Command
  • Save
  • Restore
  • Load Firmware

For detailed information on each of the above commands, see the following section of the Networking Shell Standard:

https://github.com/QualiSystems/cloudshell-standards/blob/master/Documentation/networking_standard.md#commands

Downloading the Shell

The Juniper JunOS Switch 2G shell is available from the Quali Community Integrations page.

Download the files into a temporary location on your local machine.

The shell comprises:

File name Description
JuniperJunosSwitchShell2G.zip Juniper JunOS Switch 2G shell package
cloudshell-networking-juniper-junos2-gen-dependencies-package-2.0.X.zip Shell Python dependencies (for offline deployments only)

Importing and Configuring the Shell

This section describes how to import the Juniper JunOS Switch 2G shell and configure and modify the shell’s devices.

Importing the shell into CloudShell

To import the shell into CloudShell:

  1. Make sure you have the shell’s zip package. If not, download the shell from the Quali Community's 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.

Setting the python PythonOfflineRepositoryPath configuration key

Before PyPi Server was introduced as CloudShell’s python package management mechanism, the PythonOfflineRepositoryPath key was used to set the default offline package repository on the Quali Server machine, and could be used on specific Execution Server machines to set a different folder.

To set the offline python repository:

  1. Download the cloudshell-networking-juniper-junos2-gen-dependencies-package-2.0.X.zip file, see Downloading the Shell.

  2. Unzip it to a local repository. Make sure the execution server has access to this folder.

  3. On the Quali Server machine, in the ~\CloudShell\Server\customer.config file, add the following key to specify the path to the default python package folder (for all Execution Servers):
    <add key="PythonOfflineRepositoryPath" value="repository full path"/>

  4. If you want to override the default folder for a specific Execution Server, on the Execution Server machine, in the ~TestShell\Execution Server\customer.config file, add the following key:
    <add key="PythonOfflineRepositoryPath" value="repository full path"/>

  5. Restart the Execution Server.

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.

  2. From the list, select Juniper JunOS Switch 2G shell.

  3. Enter the Name and IP address of the Juniper JunOS Switch 2G.

  4. Click Create.

  5. In the Resource dialog box, enter the device's settings. For details, see Juniper JunOS Switch Attributes.

  6. Click Continue.

    CloudShell validates the device’s settings and updates the new resource with the device’s structure.

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.
