Tutorial: Deploy your first container app

The Azure Container Apps service enables you to run microservices and containerized applications on a serverless platform. With Container Apps, you enjoy the benefits of running containers while you leave behind the concerns of manually configuring cloud infrastructure and complex container orchestrators.

In this tutorial, you create a secure Container Apps environment and deploy your first container app.

Примітка

You can also deploy this app using the az containerapp up by following the instructions in the Quickstart: Deploy your first container app with containerapp up article. The az containerapp up command is a fast and convenient way to build and deploy your app to Azure Container Apps using a single command. However, it doesn't provide the same level of customization for your container app.

Prerequisites

• An Azure account with an active subscription.
  • If you don't have one, you can create one for free.
• Install the Azure CLI.

Setup

To sign in to Azure from the CLI, run the following command and follow the prompts to complete the authentication process.

Bash

Azure CLI

az login

PowerShell

Azure PowerShell

Connect-AzAccount

To ensure you're running the latest version of the CLI, run the upgrade command.

Bash

Azure CLI

az upgrade

PowerShell

Azure PowerShell

Install-Module -Name Az -Scope CurrentUser -Repository PSGallery -Force

Ignore any warnings about modules currently in use.

Next, install or update the Azure Container Apps extension for the CLI.

If you receive errors about missing parameters when you run az containerapp commands in Azure CLI or cmdlets from the Az.App module in PowerShell, be sure you have the latest version of the Azure Container Apps extension installed.

Bash

Azure CLI

az extension add --name containerapp --upgrade

Примітка

Starting in May 2024, Azure CLI extensions no longer enable preview features by default. To access Container Apps preview features, install the Container Apps extension with --allow-preview true.

Azure CLI

az extension add --name containerapp --upgrade --allow-preview true

PowerShell

Azure PowerShell

Install-Module -Name Az.App

Make sure to update the Az.App module to the latest version.

Azure PowerShell

Update-Module -Name Az.App

Now that the current extension or module is installed, register the Microsoft.App and Microsoft.OperationalInsights namespaces.

Bash

Azure CLI

az provider register --namespace Microsoft.App

Azure CLI

az provider register --namespace Microsoft.OperationalInsights

PowerShell

Azure PowerShell

Register-AzResourceProvider -ProviderNamespace Microsoft.App

Azure PowerShell

Register-AzResourceProvider -ProviderNamespace Microsoft.OperationalInsights

Set environment variables

Set the following environment variables. Replace the <PLACEHOLDERS> with your values:

Bash

Azure CLI

RESOURCE_GROUP="<RESOURCE_GROUP>"
LOCATION="<LOCATION>"
CONTAINERAPPS_ENVIRONMENT="<CONTAINERAPPS_ENVIRONMENT>"

PowerShell

Azure PowerShell

$ResourceGroupName = '<RESOURCE_GROUP>'
$Location = '<LOCATION>'
$ContainerAppsEnvironment = '<CONTAINERAPPS_ENVIRONMENT>'

Create an Azure resource group

Create a resource group to organize the services related to your container app deployment.

Bash

Azure CLI

az group create \
  --name $RESOURCE_GROUP \
  --location "$LOCATION"

PowerShell

Azure PowerShell

New-AzResourceGroup -Location $Location -Name $ResourceGroupName

Create an environment

An environment in Azure Container Apps creates a secure boundary around a group of container apps. Container Apps deployed to the same environment are deployed in the same virtual network and write logs to the same Log Analytics workspace.

To create the environment, run the following command:

Bash

Azure CLI

az containerapp env create \
  --name $CONTAINERAPPS_ENVIRONMENT \
  --resource-group $RESOURCE_GROUP \
  --location "$LOCATION"

PowerShell

A Log Analytics workspace is required for the Container Apps environment. The following commands create a Log Analytics workspace and save the workspace ID and primary shared key to environment variables.

Azure PowerShell

$WorkspaceArgs = @{
    Name = 'myworkspace'
    ResourceGroupName = $ResourceGroupName
    Location = $Location
    PublicNetworkAccessForIngestion = 'Enabled'
    PublicNetworkAccessForQuery = 'Enabled'
}
New-AzOperationalInsightsWorkspace @WorkspaceArgs
$WorkspaceId = (Get-AzOperationalInsightsWorkspace -ResourceGroupName $ResourceGroupName -Name $WorkspaceArgs.Name).CustomerId
$WorkspaceSharedKey = (Get-AzOperationalInsightsWorkspaceSharedKey -ResourceGroupName $ResourceGroupName -Name $WorkspaceArgs.Name).PrimarySharedKey

To create the environment, run the following command:

Azure PowerShell

$EnvArgs = @{
    EnvName = $ContainerAppsEnvironment
    ResourceGroupName = $ResourceGroupName
    Location = $Location
    AppLogConfigurationDestination = 'log-analytics'
    LogAnalyticConfigurationCustomerId = $WorkspaceId
    LogAnalyticConfigurationSharedKey = $WorkspaceSharedKey
}

New-AzContainerAppManagedEnv @EnvArgs

Create a container app

Now that you have an environment created, you can deploy your first container app. With the containerapp create command, deploy a container image to Azure Container Apps.

Bash

Azure CLI

az containerapp create \
  --name my-container-app \
  --resource-group $RESOURCE_GROUP \
  --environment $CONTAINERAPPS_ENVIRONMENT \
  --image mcr.microsoft.com/k8se/quickstart:latest \
  --target-port 80 \
  --ingress external \
  --query properties.configuration.ingress.fqdn

Примітка

Make sure the value for the --image parameter is in lower case.

By setting --ingress to external, you make the container app available to public requests.

PowerShell

Azure PowerShell

$ImageParams = @{
    Name = 'my-container-app'
    Image = 'mcr.microsoft.com/k8se/quickstart:latest'
}
$TemplateObj = New-AzContainerAppTemplateObject @ImageParams
$EnvId = (Get-AzContainerAppManagedEnv -EnvName $ContainerAppsEnvironment -ResourceGroupName $ResourceGroupName).Id

$AppArgs = @{
    Name = 'my-container-app'
    Location = $Location
    ResourceGroupName = $ResourceGroupName
    ManagedEnvironmentId = $EnvId
    IdentityType = 'SystemAssigned'
    TemplateContainer = $TemplateObj
    IngressTargetPort = 80
    IngressExternal = $true

}
New-AzContainerApp @AppArgs

Примітка

Make sure the value for the Image parameter is in lower case.

By setting IngressExternal to $true, you make the container app available to public requests.

Verify deployment

Bash

The create command returns the fully qualified domain name for the container app. Copy this location to a web browser.

PowerShell

Get the fully qualified domain name for the container app.

Azure PowerShell

(Get-AzContainerApp -Name $AppArgs.Name -ResourceGroupName $ResourceGroupName).IngressFqdn

Copy this location to a web browser.

The following message is displayed when the container app is deployed:

Clean up resources

If you're not going to continue to use this application, run the following command to delete the resource group along with all the resources created in this tutorial.

Застереження

The following command deletes the specified resource group and all resources contained within it. If resources outside the scope of this tutorial exist in the specified resource group, they will also be deleted.

Bash

Azure CLI

az group delete --name $RESOURCE_GROUP

PowerShell

Azure PowerShell

Remove-AzResourceGroup -Name $ResourceGroupName -Force
