Since this is not quite straightforward, I'll write down my findings.
These are the steps to programmatically upload Application Packages via an application that is unattended - no user input (e.g. Azure credentials) is needed.
In Azure Portal:
- Create the Azure Batch application
- Create a new Azure AD application (as Application Type use
Web app / API
)
- Follow these steps to create the secret key and assign the role to the Azure Batch account
- Note down the following credentials/ids:
- Azure AD application id
- Azure AD application secret key
- Azure AD tenant id
- Subscription id
- Batch account name
- Batch account resource group name
In your code:
Put together the whole code looks something like this:
private const string ResourceUri = "https://management.core.windows.net/";
private const string AuthUri = "https://login.microsoftonline.com/" + "{TenantId}";
private const string ApplicationId = "{ApplicationId}";
private const string ApplicationSecretKey = "{ApplicationSecretKey}";
private const string SubscriptionId = "{SubscriptionId}";
private const string ResourceGroupName = "{ResourceGroupName}";
private const string BatchAccountName = "{BatchAccountName}";
private async Task UploadApplicationPackageAsync() {
// get the access token
var authContext = new AuthenticationContext(AuthUri);
var authResult = await authContext.AcquireTokenAsync(ResourceUri, new ClientCredential(ApplicationId, ApplicationSecretKey)).ConfigureAwait(false);
// create the BatchManagementClient and set the subscription id
var bmc = new BatchManagementClient(new TokenCredentials(authResult.AccessToken)) {
SubscriptionId = SubscriptionId
};
// create the application package
var createResult = await bmc.ApplicationPackage.CreateWithHttpMessagesAsync(ResourceGroupName, BatchAccountName, "MyPackage", "1.0").ConfigureAwait(false);
// upload the package to the blob storage
var cloudBlockBlob = new CloudBlockBlob(new Uri(createResult.Body.StorageUrl));
cloudBlockBlob.Properties.ContentType = "application/x-zip-compressed";
await cloudBlockBlob.UploadFromFileAsync("myZip.zip").ConfigureAwait(false);
// create the application package
var activateResult = await bmc.ApplicationPackage.ActivateWithHttpMessagesAsync(ResourceGroupName, BatchAccountName, "MyPackage", "1.0", "zip").ConfigureAwait(false);
}
