azure-msi-blob
Simple library to get and put files to Azure blob storage.
We assume your virtual machine and storage account are configured to use Azure Managed Service Identity (MSI) so you don't need any credentials to access storage from your VM.
https://docs.microsoft.com/en-us/azure/active-directory/msi-tutorial-linux-vm-access-storage
The key thing we do is get your AZURE_STORAGE_ACCESS_KEY
. This allows you to
access blob storage without any credentials both in Node.js and the azure-cli
.
Installation
npm install -g azure-msi-blob
Node.js Module Usage
// All opts are optional. We fallback to the environment variables
// described below.
const opts = {
subscriptionId: '42d18e54-a416-42fd-859c-45d9k4mfuyue3',
resourceGroup: 'some-resource-group',
accountName: 'myStorageAccount'
};
const storage = require('azure-msi-blob')(opts);
storage.get(
'some-container',
'some/blob/object.txt',
'somefile.txt',
function(err) {
// if no error your file will be on the local file system.
console.log(err);
});
storage.put(
'some-container',
'some/blob/object.txt',
'somefile.txt',
function(err) {
// if no error your file is safely in blob storage.
console.log(err);
});

The following environment variables are required for command line usage.
export AZURE_SUBSCRIPTION_ID=9di38e54-a416-42fd-859c-9dh4723h010e3

Azure Command Line Utility
If you set the AZURE_STORAGE_ACCESS_KEY
environment variable you can use
azure-cli
to do anything you want with your storage (assuming the
AZURE_STORAGE_ACCOUNT
environment variable is also set).
export AZURE_STORAGE_ACCESS_KEY=$(getkey)
create a container
az storage container create --name some_container
delete a container
az storage container delete --name some_container
