Storage¶ ↑
This document explains how to get started using Azure Storage Service with Fog
. With this gem you can create, update, list or delete storage accounts.
Usage¶ ↑
First of all, you need to require the Fog
library by executing:
require 'fog/azurerm'
Create Connection¶ ↑
Next, create a connection to the Storage Service:
fog_storage_service = Fog::Storage::AzureRM.new( tenant_id: '<Tenant Id>', # Tenant Id of Azure Active Directory Application client_id: '<Client Id>', # Client Id of Azure Active Directory Application client_secret: '<Client Secret>', # Client Secret of Azure Active Directory Application subscription_id: '<Subscription Id>', # Subscription Id of an Azure Account azure_storage_account_name: '<Storage Account Name>', # Name of an Azure Storage Account azure_storage_access_key: '<Storage Account Key>', # Key of an Azure Storage Account environment: '<AzureCloud/AzureChinaCloud/AzureUSGovernment/AzureGermanCloud>' # Azure cloud environment. Default is AzureCloud. )
If you only want to manage the storage accounts, you can create the connection without the storage account information:
fog_storage_service = Fog::Storage::AzureRM.new( tenant_id: '<Tenant Id>', # Tenant Id of Azure Active Directory Application client_id: '<Client Id>', # Client Id of Azure Active Directory Application client_secret: '<Client Secret>', # Client Secret of Azure Active Directory Application subscription_id: '<Subscription Id>', # Subscription Id of an Azure Account environment: '<AzureCloud/AzureChinaCloud/AzureUSGovernment/AzureGermanCloud>' # Azure cloud environment. Default is AzureCloud. )
If you only want to manage the storage data, you can create the connection without the Azure subscription information:
fog_storage_service = Fog::Storage::AzureRM.new( azure_storage_account_name: '<Storage Account Name>', # Name of an Azure Storage Account azure_storage_access_key: '<Storage Account Key>', # Key of an Azure Storage Account environment: '<AzureCloud/AzureChinaCloud/AzureUSGovernment/AzureGermanCloud>' # Azure cloud environment. Default is AzureCloud. )
Check Name Availability¶ ↑
This operation checks that account name is valid and is not already in use. Storage Account Type is an optional parameter
fog_storage_service.storage_accounts.check_name_availability('<Storage Account Name>', '<Storage Account Type>')
Check Storage Account Existence¶ ↑
fog_storage_service.storage_accounts.check_storage_account_exists('<Resource Group Name>', '<Storage Account Name>')
Create Storage Account¶ ↑
Create a new storage account. Replication attribute for Standard and Premium account types are as follows
Standard¶ ↑
-
LRS (Standard Locally-redundant storage)
-
ZRS (Standard Zone-redundant storage)
-
GRS (Standard Geo-redundant storage)
-
RAGRS (Standard Read access geo-redundant storage)
Premium¶ ↑
-
LRS (Premium Locally-redundant storage)
fog_storage_service.storage_accounts.create( name: '<Storage Account name>', location: '<Location>', resource_group: '<Resource Group Name>', account_type: '<Standard/Premium>', # [Optional] Default value 'Standard'. Allowed values can only be Standard or Premium replication: '<Replication Type>', # [Optional] Default value 'LRS' encryption: <True/False>, # [Optional] Enables encryption. Default is false. tags: { key1: 'value1', key2: 'value2', keyN: 'valueN' } # [Optional] )
Premium Storage account store data on solid state drives (SSDs). For more details on standard and premium storage accounts, see Introduction to Microsoft Azure Storage and Premium Storage: High-Performance Storage for Azure Virtual Machine Workloads.
List storage accounts¶ ↑
List storage accounts in a subscription¶ ↑
fog_storage_service.storage_accounts.each do |storage_acc| puts "#{storage_acc.name}" puts "#{storage_acc.location}" end
List storage accounts in a resource group¶ ↑
storage_accounts = fog_storage_service.storage_accounts(resource_group: '<Resource Group Name>') storage_accounts.each do |storage_acc| puts "#{storage_acc.name}" puts "#{storage_acc.location}" end
Retrieve a single Storage Account¶ ↑
Get a single record of Storage Account
storage_acc = fog_storage_service .storage_accounts .get('<Resource Group Name>', '<Storage Account Name>') puts "#{storage_acc.name}"
Enable encryption on Storage Account¶ ↑
Get a single record of Storage Account and enable encryption on that Storage Account
storage_acc = fog_storage_service .storage_accounts .get('<Resource Group Name>', '<Storage Account Name>') storage_acc.update(encryption: true)
Get Access Keys¶ ↑
Get access keys of a storage account
keys_hash = storage_acc.get_access_keys keys_hash.each do |keys| puts "#{keys.key_name}: #{keys.value}" end
Destroy a single Storage Account¶ ↑
Get storage account object from the get method and then destroy that storage account.
storage_acc.destroy
Create a Disk¶ ↑
Create a Disk in storage account. disk_size_in_gb must be an integer and the range is [1, 1023]. By default the disk will be created in the container 'vhds'. You can specify other container by set options.
fog_storage_service.create_disk('<Data Disk Name>', disk_size_in_gb, options = {})
Delete a Disk¶ ↑
Delete a Disk from a storage account. Disk must be in unlocked state i.e detached from server (virtual machine) to successfully perform this action. By default the disk will be deleted from the container 'vhds'. You can specify other container by set options.
fog_storage_service.delete_disk('<Data Disk Name>', options = {})
Check Storage Container Existence¶ ↑
fog_storage_service.directories.check_container_exists('<Container Name>')
Create a storage container¶ ↑
Create a storage container in the current storage account.
directory = fog_storage_service.directories.create( key: '<Container Name>', public: <True/False> ) puts directory.key
List storage containers¶ ↑
List all the storage containers in the current storage accounts.
fog_storage_service.directories.each do |directory| puts directory.key end
Get the access control level of the storage container¶ ↑
Get the permissions for the specified container. The permissions indicate whether container data may be accessed publicly.
directory = fog_storage_service.directories.get('<Container Name>', max_keys: <Maximum No. of Keys Value>) puts directory.acl
Set the access control level of the storage container¶ ↑
Set the permissions for the specified container. The permissions indicate whether container data may be accessed publicly. The container permissions provide the following options for managing container access:
-
Container¶ ↑
Full public read access. Container and blob data can be read via anonymous request. Clients can enumerate blobs within the container via anonymous request, but cannot enumerate containers within the storage account.
-
Blob¶ ↑
Public read access for blobs only. Blob data within this container can be read via anonymous request, but container data is not available. Clients cannot enumerate blobs within the container via anonymous request.
-
Nil¶ ↑
No public read access. Container and blob data can be read by the account owner only.
directory = fog_storage_service.directories.get('<Container Name>', max_keys: <Maximum No. of Keys Value>) directory.acl = '<Container Name>' directory.save(is_create: <True/False>)
Delete the storage container¶ ↑
Mark the specified container for deletion. The container and any blobs contained within it are later deleted during garbage collection.
directory = fog_storage_service.directories.get('<Container Name>', max_keys: <Maximum No. of Keys Value>) puts directory.destroy
Upload data as a block blob¶ ↑
directory = fog_storage_service.directories.get('<Container Name>', max_keys: <Maximum No. of Keys Value>) options = { key: '<Blob Name>', body: '<Blob Content>' } new_block_blob = directory.files.create(options) puts new_block_blob.inspect
