This seems like a simple thing, but I've been unable to find an answer
I'm using Azure Storage, and I have a folder in the container that has some sensitive documents in it. So I'd like to be able to "hide" the folder and it's contents from the directory listing. Is this possible? The only thing I can find is to change the Access Level of the entire container.
If there's not a way to do this, what's the proper way to hide Azure Storage docs from public access?
There is no feature in Azure Storage to hide the content in the Azure Container folder.
There is an alternate approach to secure the Azure Storage container files.
Thanks to Niclas for suggesting the same.
Assign RBAC roles to your Azure Container, like below.
Azure Portal > Storage accounts > Select your storage account > Container > Select your container > Access Control (IAM)
When I tried with another Azure AD user, who doesn't have any RBAC roles to check the Azure container files.
The user is unable to access the Azure Container.
I have assigned Storage Blob Data Contributor to the same user on Storage Account to check the Azure Container files.
Once assign the RBAC roles to the user, the same user can access the Azure Container.
Referance: Assign an Azure role for access to blob data.

I need to store some sensitive data in one container in Storage Explorer. The container has Container Public Access Level set as No public access. But still all members have access to this container. Where to change the settings (Azure Active Directory, Access policy, Acess control) to be absolutely sure that no one except two people can see the content. I need to have it under control before I put something there.
Storage Explorer supports Azure RBAC access to Storage Accounts, Blobs, and Queues which give you fine-grained access control over your Azure resources. Azure roles and permissions can be managed from the Azure portal.
You can scope access to Azure blob resources at the an individual container level: Authorize access to blobs using Active Directory - Azure Storage | Microsoft Docs
Select the container for which users access has to be controlled.
Click Access control (IAM) in the container and Click on add
assignment .
Select appropriate role to allow for the users.
And then select the users who can have the access to that container
according to the role .Please check the data actions and not data
actions to see what exact permissions apply to them

Assign roles
Just like role assignment,you can check Azure deny assignments can attach few deny actions to a user, group, or service principal for scope required to deny access.
It blocks users from performing specific Azure resource actions even if role is been granted access.

Note:Azure Blueprints and Azure managed apps are the only way
that deny assignments are used within Azure.
I have application in asp.net and uploaded to Azure App service. I have file upload on the azure blob. Here issue is my blob is accessible to public I want to access images and docs in the blobs only accessible when my application is logged in. If I log out then those should not be access. How can I achieve this using azure blob storage?
In this case, you can configure the web app with Azure AD auth(Easy Auth), follow this doc.
After doing the steps in the doc above, it will create an AD App in your AAD tenant. Navigate to the AD App in the Azure Active Directory in the portal -> API permissions, add the delegated permission of Azure Storage.
Then navigate to the authsettings of the web app in the resource explorer, add ["resource=https://storage.azure.com"] to the additionalLoginParams, details see this blog.
Navigate to the storage account in the portal -> Access control (IAM) -> make sure the user account has a role e.g. Storage Blob Data Contributor, if not, add it for the user, follow this doc.
After doing the steps above, use the user account to login the web app, you can get the access token with https://webappname.azurewebsites.net/.auth/me, then you can use the token to call the Storage REST API - GET Blob to access the things in the storage container.
In Azure DevOps, I have created a service connection (type: Azure Resource Manager) to be able to upload files to Azure Blob Storage.
Then I have added the Storage Blob Data Contributor role for this service principal under Access Control (IAM) in my Azure Storage account by searching for the service principal's name under Select.
I have noticed that each time I create a new DevOps pipeline that uses the (same) service connection, I need to add the Storage Blob Data Contributor role again because under Select, there are then multiple items with the same (service principal's) name. It's not clear why there are multiple items and it's also unclear which one is the newest, such that I am just adding all items as a workaround.
Is there anything that I am missing to avoid ending up with dozens of items to select when assigning roles for a new pipeline that uses the same service connection?
As design, one service connection map to one single service principal.
You issue mostly like you did not ever assign the actual service principal id to that service connection while you configure it. When the system finds there is no principal there, it will automatically create one for it in azure.
Please give the full parameters value there, including service principal id and secret, when you create the service connection.
Then you can just grant the permission to the currently used service principal.
I read about shared access signatures generated with stored access policies for Azure Storage from here.
I also read how to create this shared access signature with stored access policies for Azure Storage using PowerShell here.
However, I want to do the above using Azure Portal. I know how to generate an ad-hoc shared access signature. I also know how to create a stored access policy for a container in my Azure Blob.
How do I create a shared access signature with a stored access policy for an Azure Blob container in Azure Portal?
Preview of Storage Explorer is now available in Azure portal.
You can generate SAS for a container by right clicking on the container and select Get Shared Access Signature like we do in Storage Explorer using the preview
How do I create a shared access signature with a stored access policy
for an Azure Blob container in Azure Portal?
Simple answer to your question is that as of today you can't create a shared access signature (SAS) using a stored access policy in Azure Portal. This feature is not there yet. In fact, feature to create a SAS on a blob container is not there on the portal as of yet. You could only create account level SAS using Azure Portal.
If you need to create a SAS on a container using a stored access policy, please use Microsoft Storage Explorer tool (or any other storage explorer tool that has support for blobs management). Using this tool you will be able to specify a stored access policy when creating a SAS on the container.
Where can I find the file share associated with the App Service?
I can view the files from Kudo console, but I don't see the share on my Storage Account using either the portal or Storage Explorer.
While the files are backed by a storage account, it is in a platform account and not one of your own accounts. That's why you cannot see the files in storage explorer. It's also why you can create a Web App without specifying a storage account.
One exception is for Azure Functions on Consumption plan, where the user storage account is used, and you'd see the Azure Files in storage explorer.
