Limitations of Azure Cloud Shell
Azure Cloud Shell has the following known limitations:
System state and persistence
The machine that provides your Cloud Shell session is temporary, and it is recycled after your session is inactive for 20 minutes. Cloud Shell requires an Azure file share to be mounted. As a result, your subscription must be able to set up storage resources to access Cloud Shell. Other considerations include:
- With mounted storage, only modifications within the
$Homedirectory are persisted.
- Azure file shares can be mounted only from within your assigned region.
- In Bash, run
envto find your region set as
- In Bash, run
Cloud Shell supports the latest versions of Microsoft Edge, Microsoft Internet Explorer, Google Chrome, Mozilla Firefox, and Apple Safari. Safari in private mode is not supported.
Copy and paste
Ctrl-cto copy is supported but use
- FireFox/IE may not support clipboard permissions properly.
- Mac OS:
Cmd-cto copy and
For a given user, only one shell can be active
Users can only launch one type of shell at a time, either Bash or PowerShell. However, you may have multiple instances of Bash or PowerShell running at one time. Swapping between Bash or PowerShell causes Cloud Shell to restart, which terminates existing sessions.
Cloud Shell is intended for interactive use cases. As a result, any long-running non-interactive sessions are ended without warning.
Permissions are set as regular users without sudo access. Any installation outside your
$Home directory is not persisted.
Take caution when editing .bashrc, doing so can cause unexpected errors in Cloud Shell.
AzureAD module name
AzureAD module name is currently
AzureAD.Standard.Preview, the module provides the same functionality.
SqlServer module functionality
SqlServer module included in Cloud Shell has only prerelease support for PowerShell Core. In particular,
Invoke-SqlCmd is not available yet.
Default file location when created from Azure drive:
Using PowerShell cmdlets, users can not create files under the Azure drive. When users create new files using other tools, such as vim or nano, the files are saved to the
$HOME by default.
GUI applications are not supported
If the user runs a command that would create a Windows dialog box, such as
Connect-AzureRmAccount, one sees an error message such as:
Unable to load DLL 'IEFRAME.dll': The specified module could not be found. (Exception from HRESULT: 0x8007007E).
Tab completion crashes PSReadline
If the user's EditMode in PSReadline is set to Emacs, the user tries to display all possibilities via tab completion, and the window size is too small to display all the possibilities, PSReadline will crash.
Large Gap after displaying progress bar
If the user performs an action that displays a progress bar, such a tab completing while in the
Azure: drive, then it is possible that the cursor is not set properly and a gap appears where the progress bar was previously.
Random characters appear inline
The cursor position sequence codes, for example
5;13R, can appear in the user input. The characters can be manually removed.
