Deploy to Azure

Deploying your ASP.NET Core application to Azure only takes a few steps. You can do it through the Azure web portal, or on the command line using the Azure CLI. I'll cover the latter.

What you'll need

  • Git (use git --version to make sure it's installed)
  • The Azure CLI (follow the install instructions at https://github.com/Azure/azure-cli)
  • An Azure subscription (the free subscription is fine)
  • A deployment configuration file in your project root

Create a deployment configuration file

Since there are multiple projects in your directory structure (the web application, and two test projects), Azure won't know which one to publish. To fix this, create a file called .deployment at the very top of your directory structure:

.deployment

[config]
project = AspNetCoreTodo/AspNetCoreTodo.csproj

Make sure you save the file as .deployment with no other parts to the name. (On Windows, you may need to put quotes around the filename, like ".deployment", to prevent a .txt extension from being added.)

If you ls or dir in your top-level directory, you should see these items:

.deployment
AspNetCoreTodo
AspNetCoreTodo.IntegrationTests
AspNetCoreTodo.UnitTests

Set up the Azure resources

If you just installed the Azure CLI for the first time, run

az login

and follow the prompts to log in on your machine. Then, create a new Resource Group for this application:

az group create -l westus -n AspNetCoreTodoGroup

This creates a Resource Group in the West US region. If you're located far away from the western US, use az account list-locations to get a list of locations and find one closer to you.

Next, create an App Service plan in the group you just created:

az appservice plan create -g AspNetCoreTodoGroup -n AspNetCoreTodoPlan --sku F1

F1 is the free app plan. If you want to use a custom domain name with your app, use the D1 ($10/month) plan or higher.

Now create a Web App in the App Service plan:

az webapp create -g AspNetCoreTodoGroup -p AspNetCoreTodoPlan -n MyTodoApp

The name of the app (MyTodoApp above) must be globally unique in Azure. Once the app is created, it will have a default URL in the format: http://mytodoapp.azurewebsites.net

Deploy your project files to Azure

You can use Git to push your application files up to the Azure Web App. If your local directory isn't already tracked as a Git repo, run these commands to set it up:

git init
git add .
git commit -m "First commit!"

Next, create an Azure username and password for deployment:

az webapp deployment user set --user-name nate

Follow the instructions to create a password. Then use config-local-git to spit out a Git URL:

az webapp deployment source config-local-git -g AspNetCoreTodoGroup -n MyTodoApp --out tsv

https://nate@mytodoapp.scm.azurewebsites.net/MyTodoApp.git

Copy the URL to the clipboard, and use it to add a Git remote to your local repository:

git remote add azure <paste>

You only need to do these steps once. Now, whenever you want to push your application files to Azure, check them in with Git and run

git push azure master

You'll see a stream of log messages as the application is deployed to Azure.

When it's complete, browse to http://yourappname.azurewebsites.net to check out the app!
