Is there a way to get data from Azure Storage like dacpac, zip etc and put in drop folder in CI/CD pipeline?
hm, for saving files to Azure Storage, there is a Azure File Copy task. So you probably have to either use PowerShell (like the Set-AzStorageBlobContent cmdlet) or using the azcopy CLI (you might have to find an image that contains the binary)

I have CSV file uploaded to Azure blob storage and I would like to get the content of it using PowerShell script so I can use the values. I am using Azure function and was thinking about using Get-AzStorageBlobContent. However, I do not want to download the file to my local machine and can't see how I might be able to utilize the command.
I was planning on using Get-Content to get the content of the file out so I can use the values further along the script.
I would like to update static website assets from github repos. The documentation suggests to use an action based on
az storage blob upload-batch --account-name <STORAGE_ACCOUNT_NAME> -d '$web' -s .
If I see this correct, this copies all files regardless of the changes. Even if only one file was altered. Is it possible to only transfer files that have been changed? Like rsync does.
Else I would try to judge the changed files based on the git history and only transfer them. Please also answer, if you know an existing solution in this direction.
You can use azcopy sync to achieve that. That is a different tool, though.
https://learn.microsoft.com/en-us/azure/storage/common/storage-use-azcopy-blobs-synchronize?toc=/azure/storage/blobs/toc.json
https://learn.microsoft.com/en-us/azure/storage/common/storage-ref-azcopy-sync
Based on the sugggestion by #4c74356b41, I discovered that the mentioned tool was recently integrated into the az tool.
It can be used the same way as az storage blob upload-batch. The base command is:
az storage blob sync
I am trying to publish 2 files 1.ext, 2.ext into a General purpouse v2 storage account that I've just created, I've created a file share inside of it.
Question: How to save/publish a file into storage account from Azure DevOps pipeline? Which task should I use? Azure copy seems to have only two types of storage avaiable:
Yes, you can use Azure file copy task.
Run the pipeline, the file will be uploaded to target storage account:
Anyway, you can also use Azure PowerShell or Azure CLI task to upload file to storage account. Here are the tutorial for PowerShell and CLI
Update
The Source could be a file or a folder path, so you can:
Filter target files by PowerShell task in previous task, and copy it to a temporary folder.
Upload the whole folder.
For example: I just uploaded the whole project source files by setting the path to $(Build.SourcesDirectory)
And then, all the files were uploaded to storage account.
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
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]
