Apply updates to your template

6 minutes

The initial azd provisioning and deployment process is a great way to get started with your app in Azure. However, once the environment is running, you'll want to start making changes to your app code or the Azure environment.

There are a few different workflows to choose from to update your Azure environment after making changes to the azd template. You can always run azd up again to update your environment regardless of whether you changed your application code or infrastructure files. azd up will complete the package, provision, and deploy steps every time it runs, so it's a simple way to ensure all of your changes are pushed out to Azure.

However, azd also offers more granular commands that map to specific stages of the developer workflow. These commands can also save time by skipping unnecessary checks or steps that you know haven't changed.

azd deploy - This command will package and redeploy your application source code to Azure. However, it will not execute any of the infrastructure as code files that apply changes to your Azure resources.
azd provision - This command will create or update Azure resources based on changes to your infrastructure as code files. For example, azd provision will create a new storage account in Azure if you add it to your Bicep or Terraform files. However, this command does not package or redeploy your application source code.

Update the app code

Your team is building a ticket management app - not a Todo app, so you want to change the header text accordingly. Complete the following steps to update your application code and redeploy your changes using azd:

Locate the header.tsx file in the src/web/src/layout directory of the template. If you're using Visual Studio Code, you can also use the ctrl + p shortcut to search for the header.tsx file directly.

Change the header display text around line 42 from Todo to Ticket Manager and save your changes.

<Stack horizontal styles={logoStyles}>
    <FontIcon aria-label="Check" iconName="SkypeCircleCheck" className={logoIconClass} />
    <Text variant="xLarge">Ticket Manager</Text>
</Stack>

In a command prompt window set to the root of your directory, run the azd deploy command. Wait for a moment while azd redeploys your code.
```
azd deploy
```
When the command finishes, revisit your app in the browser. The text in the upper left of the header should now read Ticket Manager.

Update the Azure resources

Your team is planning to add the ability for users to upload files with their ticket, such as images or screenshots of an issue they are encountering, or other service documents. You want to add an Azure Storage account to your environment that will hold these files. You also want to make sure the storage account is included during the initial setup when this template is provisioned to future environments. You can meet these requirements by modifying the infrastructure as code files for your template using the following steps:

In the infra folder at the root of your template, open the main.bicep file.
The template already contains a reusable Bicep module for creating storage accounts, so you can use it to add your own. Paste the following code snippet at the bottom of the main.bicep file at line 180 above where the output variables are defined:
```
module storage './core/storage/storage-account.bicep' = {
  name: 'storage'
  scope: rg
  params: {
    name: '${abbrs.storageStorageAccounts}${resourceToken}'
    location: location
    tags: tags
  }
}
```
Save your changes, and then run the azd provision command. azd provision will use the infrastructure as code files in your template to update your Azure environment, but it will not redeploy any of your app source code.
```
azd provision
```
When the command finishes, follow the URL that is printed out in the console to launch the Azure portal in your browser. You should see the resource group that holds all of your originally provisioned resources, including the new storage account.

Note

When working with azd, keep in mind that infrastructure as code files are idempotent, meaning no matter how many times you run them, the desired end state will remain consistent. Bicep or Terraform will apply changes to Azure so that your environment matches the state of your infrastructure files, but changes will not be applied to resources that already match the desired state.
