Access at the container level (azure) versus blob level.

If we want to set access at the blob level will the container level access need to reset?
Which permissions has priority,... blob level or container level?

For example if we set the permissions at the Blob level as read/write however the container level permissions are read only what is the final permissions level?,... is it read only or is it read/write for the blob?

    @David Kim Since we haven't heard back from you, If the issue still persist, please feel to respond/comment back. we are happy to assist you.

    • Storage Blob Data Owner: Use to set ownership and manage POSIX access control for Azure Data Lake Storage Gen2. For more information, see Access control in Azure Data Lake Storage Gen2.
    • Storage Blob Data Contributor: Use to grant read/write/delete permissions to Blob storage resources.
    • Storage Blob Data Reader: Use to grant read-only permissions to Blob storage resources.
    • Storage Blob Delegator: Get a user delegation key to use to create a shared access signature that is signed with Azure AD credentials for a container or blob.

    You can also SAS to set different level of access and it would be more effective at different container level

    You can assign RBAC roles that are scoped to the container. Please see Grant access to Azure blob and queue data with RBAC in the Azure portal.

    You can also use Azure CLI, PowerShell, or the Storage Resource Provider API to assign RBAC roles.

    Addition information: If the issue still persist, you can refer to this Q&A thread which provides some idea on your query: https://learn.microsoft.com/en-us/answers/questions/37646/how-to-set-access-permissions-for-azure-blob-stora.html
