Azure CLI Explained: Commands, Setup, and Use Cases

Posts

Azure CLI, short for Azure Command-Line Interface, is a powerful cross-platform tool provided by Microsoft for managing Azure cloud resources. It is a command-line utility that enables developers, system administrators, and cloud engineers to interact with Azure services in a programmable and scriptable manner. While it does not replace Azure PowerShell, it serves as an efficient alternative, especially for users who prefer Unix-style commands or need a lightweight solution to interact with Azure infrastructure. Azure CLI can be run on various platforms, including Windows, macOS, Linux, and most recently, directly from a web browser via the Azure Cloud Shell.

This utility simplifies the administration of Azure cloud resources and enables users to automate cloud operations, monitor services, and manage the entire Azure environment without using the graphical interface of the Azure portal. Users can use it to create, modify, delete, or retrieve details about virtual machines, databases, resource groups, and many other services. Azure CLI is designed to provide consistency across platforms and environments, ensuring users can work efficiently regardless of the system they are operating on.

Key Features of Azure CLI

Azure CLI offers numerous features that make it a preferred choice for developers and administrators. It provides an efficient way to manage Azure resources through command-line inputs. It can be used to write scripts that automate various cloud operations, enabling organizations to save time and reduce human error. Furthermore, Azure CLI supports integration with other tools and services such as DevOps pipelines, making it a critical asset in continuous integration and continuous deployment (CI/CD) workflows.

One significant feature of Azure CLI is its ability to operate in a browser. This browser-based access, commonly referred to as the Azure Cloud Shell, allows users to use Azure CLI without installing anything on their local machines. This ensures accessibility and mobility, allowing users to manage their Azure infrastructure from virtually anywhere with an internet connection.

Understanding the Role of Azure CLI in Cloud Management

Azure CLI provides a robust interface for accessing and managing Azure resources through command-line commands. This method of access allows users to bypass graphical interfaces and directly interact with resources using predefined commands. This direct method not only speeds up operations but also enables automation, which is essential in modern cloud management.

The CLI can perform nearly every task that can be executed through the Azure portal. These include logging into the Azure account, creating and deleting resource groups, managing storage accounts, deploying virtual machines, configuring networking resources, and monitoring various cloud services. This command-line control is beneficial for users who need to perform repetitive tasks, manage resources in bulk, or embed Azure management operations into scripts or DevOps pipelines.

Benefits of Using Azure CLI

One of the primary benefits of Azure CLI is its cross-platform compatibility. Since it is available for Windows, macOS, and various Linux distributions, users can choose the operating system they are most comfortable with. This flexibility ensures broader adoption among diverse development and operations teams.

Another advantage is the command consistency provided across platforms. Once Azure CLI is installed, the commands and syntax remain the same regardless of the operating system. This consistency reduces the learning curve and helps standardize cloud operations across an organization.

Azure CLI is also ideal for automation. Through scripting, users can automate tasks such as provisioning resources, configuring security policies, managing access permissions, and monitoring infrastructure health. Scripts written using Azure CLI can be reused, modified, and shared among teams, improving collaboration and operational efficiency.

Accessing Azure CLI Without Installation

A notable feature of Azure CLI is the ability to use it directly through a web browser. This is possible through Azure Cloud Shell, a browser-accessible shell that comes pre-configured with Azure CLI and other essential tools. Users can access Cloud Shell by logging into their Azure portal and launching the shell from the interface.

This browser-based access eliminates the need for local installations, making it a convenient option for users who need quick access to Azure CLI while using public or shared computers. It also ensures that the environment is always up-to-date with the latest CLI version and configurations, which is essential for avoiding compatibility issues.

Users can also access Azure CLI through the Microsoft Azure mobile app. After signing into the app, users can launch the Cloud Shell and execute commands just like they would on a desktop environment. This level of accessibility ensures that users can manage Azure resources from virtually any device.

Installing Azure CLI on Different Operating Systems

While the Cloud Shell provides a convenient method to access Azure CLI, users may still prefer installing it on their local machines for faster access and offline usage. Azure CLI can be installed on multiple platforms, and the installation methods are tailored for each operating system to ensure seamless setup.

Installing Azure CLI on Windows

On Windows systems, Azure CLI can be installed using a Microsoft Installer (MSI) package or through PowerShell. The MSI installer is the simplest method. Users can download the installer, run it, and follow the installation wizard to complete the process. Once the installation is finished, users can verify it by running the command az– version in PowerShell or Command Prompt. This command displays the installed version of Azure CLI and ensures that it is correctly configured.

For users who prefer a command-line approach, PowerShell can be used to download and install the Azure CLI. This method involves running a set of PowerShell commands that fetch the installer and execute it silently in the background. After installation, the CLI version can be verified using the same az– version command.

Users who have installed the Chocolatey package manager can also use it to install Azure CLI by executing the command choco install azure-cli. This package manager simplifies the installation and updating process, especially for users who manage multiple development tools through Chocolatey.

Installing Azure CLI on macOS

For macOS users, the recommended way to install Azure CLI is by using Homebrew, a popular package manager for macOS. To begin, users should install Homebrew if it is not already present on their system. Once Homebrew is installed, the user must run brew update to ensure that the package manager is up to date.

To install Azure CLI, users can execute the command brew install azure-cli. If there are issues related to Python dependencies, users may need to first install or upgrade Python using brew install python3, followed by brew upgrade python3 && brew lin– -overwrite python3.

After installation, the command az– version can be used to confirm that Azure CLI has been installed successfully.

Installing Azure CLI on Linux

Azure CLI is compatible with several Linux distributions, including Ubuntu, CentOS, Fedora, and others. The installation process varies slightly depending on the distribution.

On Ubuntu, the installation is straightforward. Users can execute a single command to download and install the Azure CLI. This command fetches a Microsoft-provided script that handles the installation process automatically. This ease of installation makes Ubuntu one of the most user-friendly platforms for the Azure CLI.

On CentOS and Fedora, the process involves creating a local repository configuration for the Azure CLI. Users must add the Azure CLI repository details to their system using the echo command and then install the package using the dnf command. Once installed, Azure CLI is ready for use, and the version can be verified using the standard version command.

Getting Started with Azure CLI

Once Azure CLI is installed and operational, users can start managing Azure resources by logging in and executing commands. The interface provides a variety of features such as command history, autocomplete, and syntax highlighting to assist users in working efficiently.

Azure CLI supports interactive mode, which is designed to help beginners learn the tool. By running the az interactive command, users enter a special environment where they receive inline help, command suggestions, and examples. This mode is useful for learning new commands and understanding how to structure inputs correctly.

The first step before using most commands is to log in. This is done using the az login command, which opens a browser window where the user can enter their Azure credentials. If the user is unable to open a browser, the az login –use-device-code command can be used. This provides a device code that the user can input into a separate browser session for authentication.

For automation and service integration, users can log in using service principals or managed identities. The service principal login method involves specifying the client ID, secret, and tenant ID. This is particularly useful in CI/CD pipelines where user interaction is not possible. For Azure-hosted services like virtual machines or app services that have been assigned identities, the az login –identity command can be used to log in securely without providing credentials.

Azure CLI Command Structure

Before exploring advanced capabilities, it is essential to understand the basic syntax and structure of Azure CLI commands. The Azure CLI uses a hierarchical command structure, which starts with a base command (az) followed by a group (the Azure service being managed), a subcommand (the action to be performed), and various arguments or flags.

For example:
az group create –name myResourceGroup –location eastus

In this example, az is the base command, group specifies the resource group service, and create is the action. The –name and –location are parameters provided to define the resource group.

The structure follows a logical and consistent pattern, making it easier for users to learn commands across different services. Arguments are typically provided with a double dash prefix and can be positional or keyword-based, depending on the command.

Azure CLI also supports global arguments such as –help, which displays usage information for a command, and –output, which specifies the output format (such as JSON, table, or TSV). These options are helpful for troubleshooting and data parsing.

Managing Azure Resources with CLI

One of the most common uses of Azure CLI is managing resources within Azure subscriptions. Azure resources include a wide range of services such as virtual machines, storage accounts, databases, and web applications. The az resource group of commands provides general-purpose capabilities to interact with any Azure resource.

Working with Resource Groups

Resource groups are containers that hold related Azure resources. Managing these resource groups is fundamental to organizing and controlling cloud environments.

To create a new resource group:
az group create –name myResourceGroup –location eastus

To list all existing resource groups:
az group list –output table

To delete a resource group:
az group delete –name myResourceGroup –yes –no-wait

The –yes flag confirms deletion without further prompting, and –no-wait returns control to the user immediately without waiting for the operation to complete. These options are useful in automation scripts.

Tagging Resources

Tags are used to categorize resources for billing, reporting, or management purposes. Azure CLI allows users to apply, update, or remove tags easily.

To add a tag to a resource:
az tag create –resource-id /subscriptions/{sub-id}/resourceGroups/myGroup/providers/Microsoft.Compute/virtualMachines/myVM –tags environment=production

To list all tags applied to a resource:
az tag list –resource-id {resource-id}

Tags are particularly important in large environments where tracking resource ownership, purpose, or lifecycle stage is critical.

Managing Virtual Machines Using Azure CLI

Virtual machines (VMs) are one of the most commonly used Azure services. Azure CLI provides extensive support for managing all aspects of virtual machines, from provisioning to monitoring and deletion.

Creating a Virtual Machine

To create a basic Linux virtual machine:
az vm create –resource-group myResourceGroup –name myVM –image UbuntuLTS –admin-username azureuser –generate-ssh-keys

This command deploys a virtual machine using the Ubuntu LTS image and sets up SSH access using automatically generated keys. For a Windows VM, the image name would be different, and a password would typically be used instead of SSH keys.

Listing Virtual Machines

To view all VMs in a resource group:
az vm list –resource-group myResourceGroup –output table

The output format table displays the information in a readable, column-based format. JSON and TSV formats are also available for integration with scripts or applications.

Starting, Stopping, and Deleting VMs

To start a VM:
az vm start –resource-group myResourceGroup –name myVM

To stop a VM:
az vm stop –resource-group myResourceGroup –name myVM

To delete a VM:
az vm delete –resource-group myResourceGroup –name myVM –yes

The ability to control VMs via the CLI allows administrators to automate tasks such as scaling, maintenance, or cost management during non-peak hours.

Viewing VM Details

To retrieve detailed information about a virtual machine:
az vm show –resource-group myResourceGroup –name myVM –output json

This command returns a detailed JSON object containing configuration details, hardware profile, operating system settings, network interfaces, and disk configuration.

Networking with Azure CLI

In Azure, networking plays a critical role in the deployment and management of services. Azure CLI provides extensive support for virtual networks (VNets), subnets, public IP addresses, network security groups (NSGs), and load balancers.

Creating a Virtual Network

To create a virtual network and a subnet:
az network vnet create –resource-group myResourceGroup –name myVNet –subnet-name mySubnet

This command creates a VNet with a default address space and a single subnet.

Viewing VNets and Subnets

To list virtual networks in a resource group:
az network vnet list –resource-group myResourceGroup –output table

To show details of a specific subnet:
az network vnet subnet show –resource-group myResourceGroup –vnet-name myVNet –name mySubnet

These commands provide insights into IP ranges, connectivity rules, and dependencies between subnets and services.

Configuring Network Security Groups

Network Security Groups (NSGs) control inbound and outbound traffic to network interfaces, VMs, and subnets. They are crucial for securing Azure environments.

To create an NSG:
az network nsg create –resource-group myResourceGroup –name myNSG

To add a security rule to an NSG:
az network nsg rule create –resource-group myResourceGroup –nsg-name myNSG –name AllowSSH –priority 1000 –direction Inbound –access Allow –protocol Tcp –destination-port-range 22 –source-address-prefix ‘*’

This rule allows inbound SSH access on port 22 from any IP address. Additional rules can be created or modified to suit security requirements.

To list rules in an NSG:
az network nsg rule list –resource-group myResourceGroup –nsg-name myNSG –output table

Public IP and DNS Management

To create a static public IP address:
az network public-ip create –resource-group myResourceGroup –name myPublicIP –allocation-method Static

To associate a public IP with a VM’s network interface:
az network nic ip-config update –resource-group myResourceGroup –nic-name myNIC –name ipconfig1 –public-ip-address myPublicIP

To view public IP details:
az network public-ip show –resource-group myResourceGroup –name myPublicIP –output json

DNS configurations and custom domains can also be managed through Azure CLI using the az network dns command group. These tools allow for seamless domain resolution, internal name resolution, and zone delegation.

Monitoring and Diagnostics with Azure CLI

Azure CLI provides built-in tools for checking the health and performance of deployed services.

Monitoring Virtual Machine Metrics

To retrieve metrics such as CPU usage:
az monitor metrics list –resource /subscriptions/{sub-id}/resourceGroups/myResourceGroup/providers/Microsoft.Compute/virtualMachines/myVM –metric “Percentage CPU”

These metrics can be filtered by time interval, aggregation type, and more. This is valuable for detecting underperforming resources or unusual spikes in activity.

Diagnostic Settings

To enable diagnostic logs on a resource:
az monitor diagnostic-settings create –resource {resource-id} –name myDiagnostics –workspace {log-analytics-workspace-id} –logs ‘[{“category”: “AllMetrics”,”enabled”: true}]’

Logs can be routed to a Log Analytics workspace, Event Hubs, or Storage Accounts for further analysis.

Automating Tasks with Azure CLI Scripts

Azure CLI commands can be embedded into shell scripts for Unix-based systems or batch scripts for Windows. This enables automation of repetitive tasks and integration with deployment pipelines.

A basic deployment script for a VM might look like the following in a .sh file:

sql

CopyEdit

#!/bin/bash

az group create –name DevGroup –location westus

az vm create \

  –resource-group DevGroup \

  –name DevVM \

  –image UbuntuLTS \

  –admin-username devuser \

  –generate-ssh-keys

az vm open-port –port 80 –resource-group DevGroup –name DevVM

When executed, this script creates a resource group, deploys a VM, and opens port 80 for HTTP access.

Automation scripts improve consistency, save time, and reduce human errors in complex cloud operations.

Advanced Scripting with Azure CLI

Azure CLI enables users to go beyond basic commands by offering scripting capabilities that support conditional logic, loops, parameterization, and modularity. These capabilities are essential for performing complex deployments, repetitive operations, or cross-environment configurations.

Variables and Conditional Logic

Azure CLI can be used in shell scripts that incorporate variables and control statements to manage dynamic cloud environments. This enables scripts to adapt to different inputs or conditions.

A sample script using variables:

bash

CopyEdit

#!/bin/bash

RESOURCE_GROUP=”MyAppGroup”

LOCATION=”centralus”

VM_NAME=”MyAppVM”

az group create –name $RESOURCE_GROUP –location $LOCATION

az vm create \

  –resource-group $RESOURCE_GROUP \

  –name $VM_NAME \

  –image UbuntuLTS \

  –admin-username adminuser \

  –generate-ssh-keys

Using shell scripting features like if statements, the script can verify that resources do not already exist before creating them. For example:

bash

CopyEdit

if az group exists –name $RESOURCE_GROUP; then

  echo “Resource group already exists.”

else

  az group create –name $RESOURCE_GROUP –location $LOCATION

fi

This ensures that deployments are idempotent and reduce the risk of duplicate resource creation.

Loops for Bulk Operations

Loops can be used to perform tasks on multiple resources. For example, creating several VMs in a loop:

bash

CopyEdit

for i in 1 2 3

do

  az vm create \

    –resource-group $RESOURCE_GROUP \

    –name MyVM$i \

    –image UbuntuLTS \

    –admin-username azureuser \

    –generate-ssh-keys

done

This is particularly useful in development or testing environments where identical resources are deployed in multiples.

Reading from Files

Scripts can read resource names or configuration values from external files. This supports scalable deployments across large environments.

bash

CopyEdit

while read vmname; do

  az vm create \

    –resource-group $RESOURCE_GROUP \

    –name $vmname \

    –image UbuntuLTS \

    –admin-username azureuser \

    –generate-ssh-keys

done < vm_names.txt

Using text files for dynamic input makes scripts flexible and reusable across teams and projects.

Integrating Azure CLI into CI/CD Workflows

Azure CLI plays an essential role in continuous integration and deployment (CI/CD) by providing infrastructure provisioning, configuration management, and environment validation within automated pipelines.

Using Azure CLI in DevOps Pipelines

Many organizations use pipeline tools such as GitHub Actions, Azure DevOps, Jenkins, and GitLab CI to automate software delivery. Azure CLI can be invoked directly in these pipelines using shell script steps.

An example of an Azure DevOps pipeline using Azure CLI:

yaml

CopyEdit

steps:

– task: AzureCLI@2

  inputs:

    azureSubscription: ‘MyServiceConnection’

    scriptType: ‘bash’

    scriptLocation: ‘inlineScript’

    inlineScript: |

      az group create –name MyPipelineGroup –location eastus

      az vm create –resource-group MyPipelineGroup –name PipelineVM –image UbuntuLTS –admin-username azureuser –generate-ssh-keys

This automates the deployment of infrastructure every time a commit is pushed or a release is triggered.

Authenticating Azure CLI in Pipelines

Authentication in pipelines is usually done using a service principal with a client ID, secret, and tenant ID:

bash

CopyEdit

az login –service-principal \

  –username $AZURE_CLIENT_ID \

  –password $AZURE_CLIENT_SECRET \

  –tenant $AZURE_TENANT_ID

This method is secure and allows for non-interactive login in automated environments. These credentials are typically stored in pipeline secrets to prevent exposure.

Deploying with Infrastructure as Code

Azure CLI supports the deployment of infrastructure through declarative templates such as ARM (Azure Resource Manager) or Bicep files. These templates define the desired state of infrastructure in a JSON or domain-specific language format.

To deploy a template with Azure CLI:

bash

CopyEdit

az deployment group create \

  –resource-group MyResourceGroup \

  –template-file azuredeploy.json \

  –parameters @azuredeploy.parameters.json

This command provisions all resources defined in the template, ensuring consistency and version control.

Managing Identity and Access

Azure CLI provides tools to manage Azure Active Directory (Azure AD), users, roles, and permissions. Proper identity and access management is vital for maintaining security and compliance.

Creating Service Principals

Service principals are used for automated tools and applications to authenticate and access Azure resources.

To create a service principal:

bash

CopyEdit

az ad sp create-for-rbac –name myApp –role contributor –scopes /subscriptions/{subscription-id}/resourceGroups/MyResourceGroup

This generates credentials including app ID, password, and tenant ID. These credentials are used for authentication in scripts or pipelines.

To list service principals:

bash

CopyEdit

az ad sp list –display-name myApp

Assigning Roles

Azure uses role-based access control (RBAC) to manage permissions. Azure CLI can assign roles at subscription, resource group, or resource levels.

To assign the “Reader” role:

bash

CopyEdit

az role assignment create \

  –assignee <user-or-service-principal-id> \

  –role Reader \

  –scope /subscriptions/{subscription-id}/resourceGroups/MyResourceGroup

To list all role assignments for a user:

bash

CopyEdit

az role assignment list –assignee <user-email> –output table

This helps administrators review and audit access rights regularly.

  –resource-group MyResourceGroup \

  –template-file main.bicep

These features help avoid unintended changes or misconfigurations during infrastructure updates.

Exporting Existing Resources as Templates

Azure CLI can export current deployments as ARM templates:

bash

CopyEdit

az resource show \

  –resource-group MyResourceGroup \

  –name MyVM \

  –resource-type Microsoft.Compute/virtualMachines \

  –output json > myvm-template.json

These templates can be converted to Bicep using the Bicep CLI tool, allowing teams to adopt infrastructure as code practices without starting from scratch.

Monitoring and Diagnostics with Azure CLI

Monitoring resources is a fundamental part of managing a cloud infrastructure. Azure CLI provides a suite of tools that allow users to monitor system performance, retrieve logs, configure alerts, and visualize metrics. These capabilities enable administrators to identify system failures, resource bottlenecks, and potential security threats in real time.

Viewing Metrics with Azure CLI

Azure Monitor is a service that collects metrics and logs from Azure resources. Azure CLI can be used to query this data and generate reports.

To list available metrics for a resource:

bash

CopyEdit

az monitor metrics list-definitions \

  –resource /subscriptions/{subscription-id}/resourceGroups/MyResourceGroup/providers/Microsoft.Compute/virtualMachines/MyVM

To query specific metrics such as CPU usage:

bash

CopyEdit

az monitor metrics list \

  –resource /subscriptions/{subscription-id}/resourceGroups/MyResourceGroup/providers/Microsoft.Compute/virtualMachines/MyVM \

  –metric “Percentage CPU” \

  –interval PT1M \

  –aggregation Average

This command retrieves one-minute interval averages for CPU usage, which is helpful for performance tuning and capacity planning.

Configuring Diagnostic Settings

Azure CLI allows users to configure diagnostic settings to send logs and metrics to a Log Analytics workspace, Event Hubs, or a storage account.

To enable diagnostics for a virtual machine:

bash

CopyEdit

az monitor diagnostic-settings create \

  –name VM-Diagnostics \

  –resource /subscriptions/{subscription-id}/resourceGroups/MyResourceGroup/providers/Microsoft.Compute/virtualMachines/MyVM \

  –workspace {workspace-id} \

  –metrics ‘[{“category”:”AllMetrics”,”enabled”:true}]’ \

  –logs ‘[{“category”:”Administrative”,”enabled”:true}]’

This configuration helps ensure that administrators can analyze and correlate diagnostic data efficiently.

Creating Alerts

Azure CLI can also be used to create alerts based on thresholds or anomalies.

To create a metric alert:

bash

CopyEdit

az monitor metrics alert create \

  –name HighCPUAlert \

  –resource-group MyResourceGroup \

  –scopes /subscriptions/{subscription-id}/resourceGroups/MyResourceGroup/providers/Microsoft.Compute/virtualMachines/MyVM \

  –condition “avg Percentage CPU > 80” \

  –description “Alert when CPU usage exceeds 80 percent”

This command creates an alert rule that triggers when average CPU usage exceeds 80 percent, enabling proactive performance management.

Cost Management Using Azure CLI

Cloud costs can quickly spiral out of control if not monitored and optimized regularly. Azure CLI offers tools to view consumption, analyze spending, and manage budgets.

Viewing Usage and Costs

To list current usage details:

bash

CopyEdit

az consumption usage list –start-date 2025-06-01 –end-date 2025-06-25 –output table

This displays the usage of all resources during the specified date range. The output can be formatted as JSON for further processing.

To view current cost summaries:

bash

CopyEdit

az consumption pricesheet show –output table

This command lists the unit prices of services used during the billing period, helping administrators track resource expenses.

Creating Budgets

To ensure cost control, users can set budgets and configure alerts for overspending.

To create a budget:

  –name MonthlyBudget \

  –time-grain monthly \

  –budget-name MonthlyBudget \

  –category cost \

  –start-date 2025-06-01 \

  –end-date 2025-12-31 \

  –resource-group MyResourceGroup

Budgets help notify users when spending approaches or exceeds defined limits. Alerts can be sent via email or integrated with action groups for automated response.

Implementing Secure Automation

Security is critical in cloud environments, especially when deploying automation that accesses sensitive resources. Azure CLI supports secure credential management and provides guidelines for safe scripting.

Using Managed Identities

Managed identities eliminate the need for hardcoded credentials in scripts and automation. Azure CLI supports the use of system-assigned or user-assigned managed identities.

To enable a system-assigned identity on a virtual machine:

bash

CopyEdit

az vm identity assign –name MyVM –resource-group MyResourceGroup

To log in with a managed identity:

bash

CopyEdit

az login –identity

This is highly secure and preferred in automation scenarios such as Azure Functions, Logic Apps, or VM scripts.

Securely Storing Secrets

When using service principals in automation, secrets and credentials should never be stored in plaintext within scripts. Use secure key vaults, environment variables, or managed identities.

To access secrets from Azure Key Vault:

bash

CopyEdit

az keyvault secret show –vault-name MyKeyVault –name MySecret –query value -o tsv

This command retrieves the secret value securely and can be used in scripts without exposing credentials.

Auditing Access with Azure CLI

To review audit logs:

bash

CopyEdit

az monitor activity-log list –resource-group MyResourceGroup –output table

This allows administrators to track actions performed on Azure resources, detect unauthorized access, and enforce accountability.

Cross-Region Deployments

az alias create –name rglist –command “group list –output table”

Now the user can simply type az rglist instead of the full command.

Enable Interactive Mode

Interactive mode provides inline help, auto-completion, and command suggestions:

bash

CopyEdit

az interactive

This is especially useful for beginners or when exploring unfamiliar services.

Store Output for Further Use

Azure CLI can store command output in variables for use in subsequent commands:

bash

CopyEdit

vmId=$(az vm show –name MyVM –resource-group MyResourceGroup –query id -o tsv)

az monitor metrics list –resource $vmId –metric “Percentage CPU”

This technique improves script readability and avoids hardcoding resource IDs.

Use JSON Queries for Precision

For complex automation, JMESPath queries help extract precise values:

bash

CopyEdit

az vm list –query “[?storageProfile.osDisk.osType==’Linux’].name” –output table

This returns only the names of Linux-based VMs.

Schedule Azure CLI Jobs

Users can automate execution by scheduling tasks via cron (Linux) or Task Scheduler (Windows). For example, running a backup script every night:

bash

CopyEdit

0 2 * * * /home/user/backup.sh

This approach ensures reliability and removes the need for manual intervention.
