Azure CLI App Service Commands

This section details the Azure Command-Line Interface (CLI) commands for managing Azure App Service resources. Azure App Service is a cloud service for hosting web applications, REST APIs, and mobile back ends. The Azure CLI provides a set of commands to create, configure, and manage App Service resources.

Key Concepts

Before diving into commands, understand these core App Service concepts:

• App Service Plan: Defines the underlying compute resources for your app. It dictates the region, operating system, size, and scale count.
• Web App: The application itself, deployed to an App Service Plan. Can be a web application, API, or mobile backend.
• Deployment Slots: Allow you to manage multiple deployments of your application. Commonly used for staging and production environments.
• Configuration: Settings such as connection strings, app settings, and general application configuration.

Common Commands

Creating an App Service

To create a new web app, you first need an App Service Plan. Here's how to create both:

# Create a resource group (if you don't have one already)
az group create --name myResourceGroup --location "East US"

# Create an App Service Plan (e.g., Free tier)
az appservice plan create --name myAppServicePlan --resource-group myResourceGroup --sku F1 --is-linux

# Create a web app within the plan
az webapp create --name myUniqueAppName --resource-group myResourceGroup --plan myAppServicePlan
            

Managing Web Apps

Here are some essential commands for managing your web apps:

• List web apps:

az webapp list --resource-group myResourceGroup

• Show web app details:

az webapp show --name myUniqueAppName --resource-group myResourceGroup

• Start, Stop, Restart:

az webapp start --name myUniqueAppName --resource-group myResourceGroup
az webapp stop --name myUniqueAppName --resource-group myResourceGroup
az webapp restart --name myUniqueAppName --resource-group myResourceGroup
                

• Delete a web app:

az webapp delete --name myUniqueAppName --resource-group myResourceGroup

Deployment Slots

Deployments slots allow for safe deployment and rollback.

• Create a deployment slot:

az webapp deployment slot create --name myUniqueAppName --resource-group myResourceGroup --slot staging

• Swap slots:

az webapp deployment slot swap --name myUniqueAppName --resource-group myResourceGroup --slot staging --target-slot production

• List deployment slots:

az webapp deployment slot list --name myUniqueAppName --resource-group myResourceGroup

Configuration and Settings

Manage application settings, connection strings, and more.

• Set application settings:

az webapp config appsettings set --name myUniqueAppName --resource-group myResourceGroup --settings MySetting=MyValue AnotherSetting=AnotherValue

• List application settings:

az webapp config appsettings list --name myUniqueAppName --resource-group myResourceGroup

• Set connection strings:

az webapp config connection-string set --name myUniqueAppName --resource-group myResourceGroup --settings "AzureSQLConnectionString=Server=tcp:myserver.database.windows.net,1433;..."

Deployment

The Azure CLI supports various deployment methods. Here's an example of deploying from a local Git repository:

# Enable local Git deployment
az webapp deployment source config-local-git --name myUniqueAppName --resource-group myResourceGroup

# The command output will provide Git remote URL. Add it to your local Git repo:
# git remote add azure 

# Then push your code
# git push azure master
