Media on Umbraco Cloud
We are currently migrating all media libraries on Umbraco Cloud projects to Azure Blob Storage. This is being done to optimize the performance of Umbraco Cloud sites, and as a part of the continuous improvements added to the service.
You can follow the process on the Umbraco Cloud Statuspage.
In the article below, you can find more information about Azure Blob Storage and how it works with your Umbraco Cloud project.
All media files on your Umbraco Cloud projects are stored using Azure Blob Storage. This means that the media files are not stored with the rest of your project files but in an external storage system.
In order to access the media files on your Umbraco Cloud project you can either
- Clone your Cloud environment to your local machine (Recommended)
- Connect using Azure Storage Explorer
About Azure Blob Storage
Azure Blob Storage is an external storage system, that the Umbraco Cloud service uses to store all media files on Umbraco Cloud projects. This includes everything that is added to the Media library through the Umbraco backoffice, eg. images, PDFs, and other document formats.
You can learn more about what Azure Blob Storage is in the official documentation on Microsoft Docs.
Working with media locally
When you clone one of your Cloud environments to your local machine, you will automatically get a copy of all the media files from the Azure Blob Storage container connected to that environment.
When you add new media files to your project while working on a local clone, the files will automatically be added to the Azure Blob Storage container connected to the environment you deploy to.
One storage per environment
Each environment on your Umbraco Cloud project has a separate Azure Blob Storage container. This means that each of your environments will be using a storage container specific to that environment.
When you deploy between two environments on your Umbraco Cloud project the media files will be copied from one storage to the other, depending on which environment is being transferred to and from.
As an example, imagine that you are transferring new content changes from your Development environment to your Live environment. When you initiate the transfer, all media files from the Azure Blog Storage container connected to your Development environment will be copied and pasted into the container connected to your Live environment. Once all content changes have also been transferred, and the transfer is complete, your Media libraries on the two environments will now be in sync.
You will notice that there is a Media (
/media) folder in the root of your project files. This folder usually holds all media files associated with a Umbraco project. As your Umbraco Cloud environments are all configured with Azure Blob Storage, the media files are not in this media folder.
Instead, you will find a
web.config file in the folder. This file is used to connect the Media library on your Cloud environment to an Azure Blob Storage container.
Below is an example of how the
/media/web.config file should look by default.
<?xml version="1.0" encoding="UTF-8"?> <configuration> <system.webServer> <handlers> <clear /> <add name="AzureBlobStorageFile" path="*" verb="*" type="Umbraco.Cloud.StorageProviders.AzureBlob.FileHandler, Umbraco.Cloud.StorageProviders.AzureBlob" /> </handlers> </system.webServer> </configuration>
In some cases, you might want to connect to your Azure Blob Storage container for the environments on your Umbraco Cloud project. This could be to clean up unwanted media files or to download the current contents of the library.
Instead of connecting to your Azure Blob Storage container using the following approach, you can clone your Cloud environment to your local machine and access the files from there.
You should only use the following approach, when you do not have the option to clone down the environment to your local machine.
In order to do this, you need to know some details about the connection between the environment and the Azure Blob Storage containers. Below are the steps you need to follow, in order to locate the necessary variables:
- Access Kudu on your Cloud environment.
- Locate the "Environment" page in the top navigation.
- Scroll to the section containing "Environment variables".
There is a total of 5 variables related to the Azure Blob Storage container on your environment:
Once you have the variables, use the "Connect to Azure Storage Explorer" guide to connect to your storage container.
