Connection Information for Azure Blob storage For ImageSharp


Hello, we're working with the Optimizely.ImageSharp.Web Library on CMS 12, and it requires Azure Blob Storage connection information for DXP sites. Previously for the Windows based (CMS 11) clients the keys to pull from the Web.config were 'EPiServerAzureBlobs', and there was no blob container needed.  Does anyone know what the keys are for configuration in CMS 12 without a Web.config?

You should be able to configure this in StartUp.cs, like the DXP-example shows here:

Basically you specify connection yourself based on what you have configured in appSettings.json.

From appSettings.json:

"ConnectionStrings": {
        "EPiServerDB": "",
        "EcfSqlConnection": "",
        "EPiServerAzureBlobs": "",
        "EPiServerAzureEvents": ""

In StartUp.cs

var blobConnection = _configuration.GetConnectionString("EPiServerAzureBlobs");
imageSharpBuilder.Configure<AzureBlobStorageCacheOptions>(options =>
                    options.ConnectionString = blobConnection;
                    options.ContainerName = "resizer-cache";

Hi Mari,

I can see classes AzureBlobStorageCacheOptions and AzureBlobStorageCache in your answer. I can't find these classes in my solution. It looks that I missed some package (or using a wrong version of the package). Could you please provide me with a full names these classes?

Thank you in advance.

These classes are part of the ImageSharp library that this original questions refers to:
Package name: SixLabors.ImageSharp.Web.Providers.Azure

Hi Mari,

Thank you! I added package "SixLabors.ImageSharp.Web.Providers.Azure" and it looks OK now.

Thanks! The connection string worked perfectly, but I wasn't able to use 'resizer-cache' as it wasn't a valid container in my DXP environment? Using the default blob storage container name `mysitemedia` worked perfectly though. Thank you!

Great to hear!

I am not familiar with DXP, but I assume you can ask hosting to create cache container for you?
