Uploading a file to azure storage account as a blob with authentication using managed identities
I want to upload a text file from a VM to storage account. For this I have created a VM with system assigned managed identity enabled. I assigned the managed identity to Storage account as RBAC policy (given the Storage Blob Data Owner permissions). I now want to upload the file in a container name log using curl request (since I don't have az cli installed in the VM). How can I do that.
The file that I want to upload is test.txt and want to upload with same name.
Thanks
Uploading a file to azure storage account as a blob with authentication using managed identities.
There are several ways to upload files to a storage account.
Method 1:
Upload a file to a storage account using a SAS token with the 'curl' command.
- Go to the storage account and generate a
SAStoken with the required permissions
- Run the following command to copy the file from the Linux VM to the storage account using curl..
curl -H "x-ms-blob-type: BlockBlob" --upload-file samplefile.txt --url "https://venkat12.blob.core.windows.net/log/samplefile.txt?<SAS_Token>"
Output:
The file has been uploaded to the storage account.
Method 2: : Azcopy with managed Identity
Download AzCopy:
wget https://aka.ms/downloadazcopy-v10-linux
Extract the AzCopy
tar -xvf downloadazcopy-v10-linux
Move the AzCopy to a Directory
sudo cp ./azcopy_linux_amd64_*/azcopy /usr/local/bin/
Verify the Installation:
azcopy --version
Login : sudo azcopy login --identity
Execute the command below to upload the files to the storage account.
sudo azcopy copy '/home/Venkat/samplefile.txt' 'https://venkat12.blob.core.windows.net/log/samplefile.txt'
