When it comes to IT automation, there are still worries about scripting because scripting can be a slow, time-consuming process, and it can be difficult for maintenance.

When something goes wrong, nobody knows what happened, who is the guy who wrote those scripts?

And, we have to mention that it’s hard to keep documentation up to date.

On the other hand, we have to admit that there are major advantages of automation that include:

  • easy to learn and use
  • minimum programming knowledge or experience required
  • allow complex tasks to be performed in relatively few steps
  • allow simple creation and editing in a variety of text editors
  • allow the addition of dynamic and interactive activities to web pages
  • editing and running code is fast

Scripting languages are becoming more popular due to the need to automate our day-to-day tasks. Every VMware administrator must automate basic tasks in order to save time. Managing Hyper-V and vSphere with Command-Line Interfaces is essential.

vSphere supports several command‐line interfaces for managing your virtual infrastructure including a set of ESXi Shell commands, PowerCLI commands, and DCLI commands for management of vCenter services. You can run commands locally, from an administration server, or from scripts.

What is vSphere CLI?

vSphere command-line interfaces allow you to administer your VMware virtual environment. vSphere command-line interfaces enable you to automate common tasks that you perform to deploy and support your virtual datacenter such as configuring and managing storage for the ESXi hosts and setting up networking for virtual machines.

Below is an overview of vSphere Command-Line Interfaces from the VMware website:

vSphere Command-Line

ESXCLI commands: Manage many aspects of an ESXi host. You can run ESXCLI commands remotely or in the ESXi Shell. You can also run ESXCLI commands from the vSphere PowerCLI prompt by using the Get-EsxCli cmdlet.

vCLI package: Install the vCLI package on the server of your choice.

  • ESXi Shell: Run ESXCLI commands in the local ESXi shell to manage that host
  • Vicfg: Allow users to manage hosts remotely. Install the vCLI package on a Windows or Linux system or deploy a vMA virtual machine, and target the ESXi system that you want to manipulate

VMware PowerCLI: VMware vSphere PowerCLI provides a Windows PowerShell interface to the vSphere API. vSphere PowerCLI includes PowerShell cmdlets for administering vSphere components. It also includes many cmdlets and, a set of sample scripts for management and automation. More information about PowerCLI here: Managing vSphere using VMware PowerCL

DCLI commands: Let’s see what is DCLI in the next section.

What is VMware Datacenter CLI?

VMware DCLI means VMware Datacenter Command-Line Interfaces, which is used to manage VMware vCenter. DCLI is a CLI client, a DCLI command talks to a VMware API endpoint to locate relevant information and then executes the command and displays result to the user.

You can run DCLI commands as follows:

vCenter Server Appliance. Run DCLI commands from the vCenter Server Appliance shell.

vCenter Server Windows command prompt. Install vCenter Server on a supported Windows system and run DCLI commands from the command prompt.

Scripts. Use scripts that include DCLI commands and run the scripts as vCLI scripts from the vCenter Server Windows command prompt or from the vCenter Server Appliance shell.

Thanks to VMware DCLI, you can retrieve information about your vCenter infrastructure (Network, storage, VMs, …) and you can also manage your VMware resources (create, delete, …) as you can perform using PowerCLI.

Running DCLI Commands on the vCenter Server Appliance

The first thing to perform is to connect to your vCenter server using the SSH protocol. On a Windows machine, open Putty and then type the root credentials. One thing to notice is the syntax.

Unlike other scripting languages that use a “-” in front of each parameter, VMware DCLI will use ‘+’ instead of ‘-‘.

To start a DCLI session, use the following command:

Command> dcli +interactive


In this example, the interactive shell uses the dcli> prompt which is the default but you can customize the prompt:

dcl> dcli +interactive +prompt VMwareDCLI

prompt VMwareDCLI

Thanks to the interactive mode, you can autocomplete your command. Type the command and then press the spacebar or TAB, to display the available options:


If you need more information about a command, use the –help parameter:


I can easily retrieve information about a specific Virtual Machine. First, I can use the ‘list’ command:

VMwareDCLI> vCenter vm list –names XXXXX

This command returns some basic information such as:

  • VM ID
  • VM Name
  • Power State
  • CPU Count
  • Memory Size

The VM ID is important and can be used with the ‘get’ command:

VMwareDCLI> vCemter vm get –vm YYYYYYY


Using DCLI with a Credential Store File

To avoid typing the username and password each time you run a DCLI command, you can add the current user and the associated password to a credential store file by using the credstore-add option on the command line.

In the following example, I can list the current credential store file using:

Command> dcli +credstore-list


Now, let’s run the ‘credstore-add’ command from a Windows machine to add a new credential store entry.


dcli com vmware cis tagging tag list +credstore-add +username user1


DCLI History File

DCLI maintains a history file for each DCLI client that runs in interactive mode, which is located in the following directory:



The file stores information on a per‐user basis and not on a per‐client basis.

Running DCLI Commands from a Windows Machine

The first thing to do is to install the vSphere CLI package. So download the package from the VMware website:


As you can notice, the package was released in 2016. A few days ago, the VMware team has released the latest version, which is no longer available in the vSphere CLI package.

You must install Python and PyPI: to install DCLI. PyPI is the official 3rd party public repository for Python. PyPI will download and install DCLI onto your local system:


Let’s confirm if Python and PIP are installed:


Then you can run the installation process using the following command:

> pip install dcli


You can still work with DCLI using the vSphere CLI package, but using this way, DCLI will be released on a more regular cadence. So you should use ‘pip’ to work with the latest version.

In my current lab, I will use the vSphere CLI package. First, use the following command to connect to your vCenter server:

> dcli.exe +server https://vCenter/api +interactive +prompt dcli> +skip-server-verification


Below are some basic examples.

  1. List the Virtual Machines in a specific Power State:
  2. VMwareDCLI

  3. Retrieve CPU information for a specific VM:
  4. VMwareDCLI

  5. Show the system time:
  6. VMwareDCLI

The advantage of DCLI instead of PowerCLI is, it is very simple to use whereas, in DCLI, you must learn a new syntax, also the scripting language is more complex. So, I advise you to use PowerCLI for VMware administrators who are familiar with PowerShell. If you don’t use PowerShell, then you can try VMware DCLI to suit your needs.
