How to use the command 'az webapp' (with examples)

Azure Cloud Services provides a powerful platform for hosting web applications in the cloud. The az webapp command is a part of the Azure CLI (Command-Line Interface) and allows users to manage their web applications hosted in Azure Cloud Services. This article provides examples and explanations for several common use cases of the az webapp command.

Use case 1: List available runtimes for a web application

Code:

az webapp list-runtimes --os-type windows|linux

Motivation:

When developing a web application, it is important to select the appropriate runtime environment. The az webapp list-runtimes command provides a convenient way to list available runtimes for different operating systems (Windows or Linux). This helps developers determine the best runtime for their web application.

Explanation:

• az webapp list-runtimes: This command lists the available runtimes for web applications.
• --os-type: This argument specifies the operating system type. It accepts either “windows” or “linux” as values.

Example output:

[
  {
    "name": "PYTHON",
    "version": "3.8",
    "isDefault": true
  },
  {
    "name": "JAVA",
    "version": "8",
    "isDefault": false
  },
  {
    "name": "NODE",
    "version": "12-lts",
    "isDefault": false
  }
]

Use case 2: Create a web application

Code:

az webapp up --name name --location location --runtime runtime

Motivation:

Creating a web application in Azure Cloud Services can be a complex process. The az webapp up command simplifies this process by automating the deployment of a web application. By providing the necessary arguments, users can easily create a web application in their desired location with a specific runtime.

Explanation:

• az webapp up: This command creates a web application in Azure Cloud Services.
• --name: This argument specifies the name of the web application.
• --location: This argument specifies the location where the web application should be created.
• --runtime: This argument specifies the runtime environment for the web application.

Example output:

Creating App Service plan 'xxx'...
Creating webapp 'name'...
Webapp 'name' created successfully.

Use case 3: List all web applications

Code:

az webapp list

Motivation:

When managing multiple web applications in Azure Cloud Services, it is important to have a comprehensive overview of all the applications. The az webapp list command provides a simple way to list all the web applications, including their names and other relevant information. This helps users keep track of their web applications and perform targeted actions if needed.

Explanation:

• az webapp list: This command lists all the web applications hosted in Azure Cloud Services.

Example output:

[
  {
    "name": "webapp1",
    "state": "Running",
    "location": "West US",
    "runtimeStack": "PYTHON|3.8"
  },
  {
    "name": "webapp2",
    "state": "Stopped",
    "location": "East US",
    "runtimeStack": "NODE|12-lts"
  }
]

Use case 4: Delete a specific web application

Code:

az webapp delete --name name --resource-group resource_group

Motivation:

At times, it may be necessary to delete a specific web application in Azure Cloud Services. The az webapp delete command allows users to easily delete a web application by providing its name and the corresponding resource group. This provides a quick and streamlined way to remove unwanted or obsolete web applications.

Explanation:

• az webapp delete: This command deletes a specific web application in Azure Cloud Services.
• --name: This argument specifies the name of the web application to be deleted.
• --resource-group: This argument specifies the resource group which contains the web application.

Example output:

Deleting webapp 'name'...
Webapp 'name' deleted successfully.

Conclusion:

The az webapp command is a valuable tool for managing web applications hosted in Azure Cloud Services. By using the command in various use cases such as listing available runtimes, creating and deleting web applications, and listing all web applications, users can effectively manage their web application infrastructure and streamline their development and deployment processes.
