App Service

Create an App Service and deploy with source code

Prerequisite

Create an Azure Account
Setup Azure CLI
Log in with Azure CLI
Create a resource group.
To learn these steps, please check Azure CLI content.

Create an App Service plan

Command:

$ az appservice plan create \
  --name <APP_SERVICE_PLAN_NAME> \
  --resource-group <RESOURCE_GROUP_NAME> \
  --location <LOCATION> \
  --is-linux \
  --sku <SKU>

To list all existing service plans, use az appservice plan list --output table.
To list all locations, use az account list-locations --output table.
SKU value are B1, B2, B3, D1, F1, FREE, I1, I1v2, I2, I2v2, I3, I3v2, P1V2, P1V3, P2V2, P2V3, P3V2, P3V3, PC2, PC3, PC4, S1, S2, S3, SHARED.
- Free SKU is for free pricing tier.
- B1 SKU is for the cheapest pricing tier for Linux OS.

Example code to create an app service plan with free pricing tier:

$ az appservice plan create \
  --name codesanook-example-app-service-plan \
  --resource-group codesanook-example-resource-group \
  --location southeastasia \
  --is-linux \
  --sku FREE

Example code to create an app service plan with the cheapest pricing tier:

$ az appservice plan create \
  --name codesanook-example-app-service-plan \
  --resource-group codesanook-example-resource-group \
  --location southeastasia \
  --is-linux \
  --sku B1

Create an App Service for deploying with source code

Command:

$ az webapp create \
  --name <APP_SERVICE_NAME> \
  --plan <APP_SERVICE_PLAN_NAME> \
  --resource-group <RESOURCE_GROUP_NAME> \
  --runtime <RUNTIME>

Access a website as https://APP_SERVICE_NAME.azurewebsites.net.
To list all existing App Service, use az webapp list --output table.
To list all supported runtime, use az webapp list-runtimes.
Note, you need to wrap double quote to a runtime value.
After your App Service is ready, it will deploy your source code from a Git server. You can log in to Azure portable to check deployment status.
More details for App Service

Example code to create an empty app service that we will deploy with GitHub Actions:

$ az webapp create \
  --name codesanook-example-app-service \
  --plan codesanook-example-app-service-plan \
  --resource-group codesanook-example-resource-group \
  --runtime "DOTNETCORE:8.0"

Deploy a project with GitHub Actions

You can use our GitHub Actions workflow script to deploy your project to Azure App Service that you’ve just created.
To deploy with GitHub Actions, you need to have Azure App Service publish profile.
Before getting App Service profile you need to WEBSITE_WEBDEPLOY_USE_SCM configuration’s value to true

Update Azure App Service configuration

Command:

$ az webapp config appsettings set \
  --name <APP_SERVICE_NAME> \
  --resource-group <RESOURCE_GROUP_NAME> \
  --settings @<CONFIGURATION_JSON_FILE>

Example code to update Azure App Service configuration:

$ az webapp config appsettings set \
  --name codesanook-example-app-service \
  --resource-group codesanook-example-resource-group \
  --settings @app-service-configuration.json

Example content of a configuration JSON file:

[
  {
    "name": "WEBSITE_WEBDEPLOY_USE_SCM",
    "value": "true",
    "slotSetting": false
  }
]

Get Azure App Service publish profile

Command:

$ az webapp deployment list-publishing-profiles \
  --name <APP_SERVICE_NAME> \
  --resource-group <RESOURCE_GROUP_NAME> \
  --xml

Example code to get Azure App Service publish profile:

$ az webapp deployment list-publishing-profiles \
  --name codesanook-example-app-service \
  --resource-group codesanook-example-resource-group \
  --xml

After you have App Service publish profile, you can use it in our custom GitHub workflow to deploy App Service with source code.
Deploy .NET app to Azure App Service code

Get FTPS Credentials

Go to Azure portal.
Select your app service.
In app service page that you have selected, select Deployment Center. Then click FTPS credentials tab.
You will find all required information to make an FTPS connection.
- FTPS endpoint
- Username
- Password

Other useful commands

Delete an existing Azure App Service

Command:

$ az webapp delete \
  --name <APP_SERVICE_NAME> \
  --resource-group <RESOURCE_GROUP_NAME>

Example code to delete an existing App Service:

$ az webapp delete \
  --name codesanook-example-app-service \
  --resource-group codesanook-example-resource-group

Create for a container

az webapp create \
  --name md-burner \
  --plan codesanook-example-app-service-plan \
  --resource-group codesaook-example-group \
  --deployment-container-image-name mcr.microsoft.com/dotnet/samples:aspnetapp \
  --debug

Useful resources

Add a custom domain

Command:

az webapp config hostname add \
  --webapp-name <app-name> \
  --resource-group <resource_group_name> \
  --hostname <fully_qualified_domain_name>

Example code to create a custom domain

az webapp config hostname add \
  --webapp-name codesanook-example-app-service \
  --resource-group codesanook-example-resource-group \
  --hostname www.codesanook-example.com

Delete a custom domain

Command:

az webapp config hostname delete \
  --webapp-name <app-name> \
  --resource-group <resource_group_name> \
  --hostname <fully_qualified_domain_name>

Example code to create a custom domain

az webapp config hostname delete \
  --webapp-name codesanook-example-app-service \
  --resource-group codesanook-example-resource-group \

Get verification ID

# add extension to Azure CLI
az extension add --name resource-graph

# Run query
az graph query -q "Resources | project name, properties.customDomainVerificationId, type | where type == 'microsoft.web/sites'"

query="Resources"
query+=" | project name, properties.customDomainVerificationId, type"
query+=" | where type == 'microsoft.web/sites'"

az graph query -q "$query"

Building on SupriyaGangineni’s reply…

The domain verification id is the same for all app services on the same subscription. the following query gives you a list of all subscriptions you have access to.

az graph query -q "Resources | join kind=leftouter (ResourceContainers | where type=='microsoft.resources/subscriptions' | project SubName=name, subscriptionId) on subscriptionId | where type == 'microsoft.web/sites'| project vid = tostring(properties.customDomainVerificationId), SubName | distinct *"
