How do I figure out what storage account and file share is currently being used by my cloud shell? Get-AzStorageAccount just gives a list of all the storage accounts...
You could run the df command on the Cloud Shell to discover which file share is mounted as clouddrive. For example, there is a file share path //storageaccountname.file.core.windows.net/filesharename

I wonder where are the files saved in Azure Shell text editor located in Azure Portal? In my understanding, when I lunched Azure Shell the very 1st time, a Storage Account and cloud-shell-storage-(region) Resource Group were automatically created for me in Azure Resources. But, when I open cloud-shell-storage-(region) Resource Group in Azure Portal and go to Storage Explorer (preview)/FILE SHARES, I don't see any files that I previously saved in Azure Shell text editor. At the same time, I run ls command in Azure Shell and I can see them all. Is it possible to see those files from Azure Portal at all?
Only the files located in /home/username/clouddrive directory can be seen in the storage file share, the files you stored in /home/username will be stored in the img file e.g. acc_joy.img in the .cloudconsole directory of your file share, you cannot see them.
So if you want to access the file in the file share, you need to store your file in the /home/username/clouddrive, follow the steps below.
Sample:
1.Run cd ./clouddrive/ to go the clouddrive.
2.Run code testfile.txt, the testfile.txt is the file you want to create and store, then the cloud shell will open the editor for you, you could input your stuff, then Save it.
3.Then go to your storage file share, you will find the file is existing.
It also can be available in Storage Explorer (preview).
I don't know how to connect to an existing Azure File Share from Azure Cloud Shell.
The command clouddrive seems to move my default cloud shell storage account. But I don't want to do that. I just want to access my existing Azure File Share storage. This can exist in any Azurea region (not just what's available for Cloud Shell, which is currently very limited)
When I tried to use clouddrive to mount my existing Azure Files account, I get the following error message:
ERROR: The storage account is not in the valid location. Expect: eastus Actual: canadacentral
I'd prefer not to move my existing Azure File Shares from canadacentral to eastus. Is there a workaround for this?
I'd like to just connect to my existing Azure File Shares through Cloud Shell and run commands in those directories.
Thank you!
Same question asked here:
https://github.com/MicrosoftDocs/azure-docs/issues/42001
https://serverfault.com/questions/992834/connect-to-azure-file-share-from-azure-cloud-shell
Azure cloud shell is an interactive, authenticated, browser-accessible shell which backend is running on cloud shell hosts. The cloud shell machines are temporary but your files are persisted through a mounted file share named clouddrive.
By using the advanced option, you can associate existing resources. Also, the associated Azure storage accounts must reside in the same region as the Cloud Shell machine that you're mounting them to. To find your current region you may run env in Bash and locate the variable ACC_LOCATION.
As the document stated, the canadacentral is not an available region for Cloud Shell, you should mount file storage in the available region. If so, you can run clouddrive unmount to unmount the current file share then select the existing file storage in the available region via clicking advanced settings in the initial login.
I have one large file on my azure blob storage container. I want to move my file from blob storage to Linux VM created on azure> How can I do that using data factory? or any Powershell Command?
The easiest and without any tools is to generate SAS token for the blob and run CURL.
Generate SAS
And then CURL
curl <blob_sas_url> -o output.txt
If you need this automated every time you can generate SAS URL from the script or just use AzCopy.
Please reference this blog：How to copy data to VM from blob storage, it gives you a way to solve the problem with Data Factory:
"To anyone who might get into same problem in future, I solved my problem by using 'copy wizard' present in ADF.
We need to install Data Management Gateway on VM and register it before we use 'copy wizard'.
We need to specify blob storage as source and in destination we need to choose 'File Server Share' option. In 'File Server Share' option we need to specify user credentials which I suppose pipeline uses to login to VM, folder on VM where pipeline will copy the data."
From the Azure Blog Storage document, there is another way can help you Mount Blob storage as a file system with blobfuse on Linux.
Blobfuse is a virtual file system driver for Azure Blob storage. Blobfuse allows you to access your existing block blob data in your storage account through the Linux file system. Blobfuse uses the virtual directory scheme with the forward-slash '/' as a delimiter.
This guide shows you how to use blobfuse, and mount a Blob storage container on Linux and access data. To learn more about blobfuse, read the details in the blobfuse repository.
If you want to use AzCopy, you can reference this document Transfer data with AzCopy and Blob storage. You can download the AzCopy for Linux. It provided the command for upload and download files.
For example, upload file:
azcopy copy "<local-file-path>" "https://<storage-account-name>.<blob or dfs>.core.windows.net/<container-name>/<blob-name>"
For PowerShell, you need to use PowerShell Core 6.x and later on all platforms. It works with Windows and Linux virtual machines using Windows PowerShell 5.1 (Windows only) or PowerShell 6 (Windows and Linux).
You can find the PowerShell commands in this document:Quickstart: Upload, download, and list blobs by using Azure PowerShell
Here is another link talked about Copy Files to Azure VM using PowerShell Remoting 6 (Windows and Linux).
Hope this helps.
You have many options to copy content from the blob store to the disk on the VM:
1. Use AzCopy
2. Use Azure Pipelines - File copy task
3. Use Powershell cmdlets
A lot of content is available on these approaches on SO!
It seems this is not properly documented anywhere so I am sharing the most basic approach which is to use the azcopy tool that is available for both windows/linux OS. This approach doens't need the complexity of creating the credentials/tokens.
Download azcopy
Its simple executable which can be run directly after extraction
Create a managed identity(system-assigned identity) for your Virtual machine. Navigate to VM-> Identity -> Turn the Status to 'ON' -> Save
Now the VM can be assigned permission at the following levels:
Storage account
Container (file system)
Resource group
Subscription
For this case, navigate to storage account -> IAM -> Add role assignment -> Select role 'Storage Blob Data Contributor' -> Assign access to 'Virtual machine' -> Select the desired VM -> SAVE
NOTE: If you give access to the VM on IAM properties of a Resource Group, the VM will be able to access all the storage accounts of the RG.
Login to VM and assume the identity (run the command from the same location where the azcopy is located)
For windows : azcopy login --identity
For linux : ./azcopy login --identity
Upload or download the files now:
azcopy cp "source-file" "storageUri/blob-container/" --recursive=true
Example: azcopy cp "C:\test.txt" "https://mystorageaccount.blob.core.windows.net/backup/" --recursive=true
IAM permission can take few minutes to propagate. If you change/add the permissions/access level anywhere, run the azcopy login --identity command again to get the updated identity.
More info on Azcopy is available here
Technical Stack
MarkLogic 9.0
Cenos Linux
Azure Blob
Blobfuse
To make sure we do not have to worry about data disk size for MarkLogic Forest, we have configured Azure Blob to one of folder in Linux machine, so we do not have to worry about disk size.
There are few things i noticed
Need to create folder in Linux
Create folder and point it to above folder
Then configure Blobfuse else we are getting permission denied while creating forest
Use below command to give permission to all
chmod 777 -R
Now when we started importing using MarkLogic Content Pump (MLCP)
19/03/15 17:01:19 ERROR mapreduce.ContentWriter: SVC-FILSTAT: File status error: stat64 '/mnt/mycontainer/Forests/forest-01/000043e5': Permission denied
So if you look at below image
1st we tried with mycontainer but as soon as we map it to Azure Blob, it does not looks green as azureblob which is. We still need to map azureblob to "azureblob" folder.
It seems i am missing something here, anything to do with Azure Blob security settings?
With the test, when you mount the Azure Blob to Linux, for example, Ubuntu 18.04 (which I'm using), if you want to allow other users to use the mount directory, you can add the parameter -o allow_other when you execute the command blobfuse.
To allow access to all users, you can mount via the option -o
allow_other.
Also, I think you should give others permission through the command chown. For more details, see How to mount Blob storage as a file system with blobfuse.
First i would like to thanks Charles for his efforts and extended help on this issue, Thanks Charls :). I am sure this will help me sometime, somewhere.
I got link on how to setup MarkLogic on Aure
On Page No. 27, steps to Configuring MarkLogic for Azure Blob Storage
In summary it is
Create Storage account in Azure
Create Blob container
Go to MarkLogic server (http://localhost:8001)
Go to Security -> Credentials
Provide Storage account and Azure storage key
While creating MarkLogic Forest, mentioned container path in data directory
azure://mycontainer/mydirectory/myfile
And you are done. No Blobfuse, no drive mount, just a configuration in MarkLogic
Awesome!!
Its working like dream :)
Is there a way to upload multiple files to Azure Blob Storage from a Linux machine, either using the terminal or an application (web based or not)?
Thank you for your interest – There are two options to upload files in Azure Blobs from Linux:
Setup and use XPlatCLI by following the steps below:
Install the OS X Installer from http://azure.microsoft.com/en-us/documentation/articles/xplat-cli/
Open a Terminal window and connect to your Azure subscription by either downloading and using a publish settings file or by logging in to Azure using an organizational account (find instructions here)
Create an environment variable AZURE_STORAGE_CONNECTION_STRING and set its value (you will need your account name and account key): “DefaultEndpointsProtocol=https;AccountName=enter_your_account;AccountKey=enter_your_key”
Upload a file into Azure blob storage by using the following command: azure storage blob upload [file] [container] [blob]
Use one of the third party web azure storage explorers like CloudPortam: http://www.cloudportam.com/.
You can find the full list of azure storage explorers here: http://blogs.msdn.com/b/windowsazurestorage/archive/2014/03/11/windows-azure-storage-explorers-2014.aspx.
You can use the find command with the exec option to execute the command to upload each file, as described here as described here:
find *.csv -exec az storage blob upload --file {} --container-name \
CONTAINER_NAME --name {} --connection-string=‘CONNECTION_STRING’ \;
where CONNECTION_STRING is the connection string of your Azure Blob store container, available from portal.azure.com. This will upload all CSV files in your directory to the Azure Blob store associated with the connection string.
If you prefer the commandline and have a recent Python interpreter, the Azure Batch and HPC team has released a code sample with some AzCopy-like functionality on Python called blobxfer. This allows full recursive directory ingress into Azure Storage as well as full container copy back out to local storage. [full disclosure: I'm a contributor for this code]
