Azure.jl

A Julia library to access Microsoft Azure REST APIs. Most code in this file is generated automatically using OpenAPI.jl

An Azure service principal is used as credentials. It can be created from Azure portal UI, or from az command line. e.g.:

command:

az ad sp create-for-rbac --role="Owner" --scopes="/subscriptions/subscrip-tion-idxx-xxxx-xxxxxxxxxxxx"

result:

    {
      "appId": "appidxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
      "displayName": "azure-cli-2017-04-26-10-16-19",
      "name": "http://azure-cli-2017-04-26-10-16-19",
      "password": "password-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
      "tenant": "tenantid-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
    }

Create AzureCredentials with a service principal (tenant_id, appid, password)

creds = AzureCredentials("tenantid-xxxx-xxxx-xxxx-xxxxxxxxxxxx", 
                         "appidxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx", 
                         "password-xxxx-xxxx-xxxx-xxxxxxxxxxxx")
ctx = AzureContext(creds)

Call APIs

Each API client module has corresponding API methods that can be invoked by providing an instance of the API and the API version.

The api method returns an instance of the API. E.g.: api(ctx, StorageManagementClient.OperationsApi).

The apiver method returns the version of the API. E.g.: apiver(StorageManagementClient.OperationsApi)

The API methods return a tuple of the decoded response value and the associated HTTP response object. The Azure.check_api_response method can be used to examine the HTTP response and either throw an exception (Azure.AzureException) on error or return the response value on success. E.g.:

list = Azure.check_api_response(StorageManagementClient.operations_list(
    api(ctx, StorageManagementClient.OperationsApi),
    apiver(StorageManagementClient.OperationsApi)
  ))

List operations

Azure.check_api_response(StorageManagementClient.operations_list(
    api(ctx, StorageManagementClient.OperationsApi),
    apiver(StorageManagementClient.OperationsApi)
  ))

Azure.check_api_response(ComputeManagementClient.operations_list(
    api(ctx, ComputeManagementClient.ComputeOperationsApi),
    apiver(ComputeManagementClient.ComputeOperationsApi)
  ))

Get a VM and list out some of its attributes

const subscription_id = "subscrip-tion-idxx-xxxx-xxxxxxxxxxxx"
vm = Azure.check_api_response(virtual_machines_get(
    api(ctx, ComputeManagementClient.VirtualMachinesApi), 
    "test-resource-grp",
    "my-vm-name", 
    apiver(ComputeManagementClient.VirtualMachinesApi), 
    subscription_id
  ))

vm_props = vm.properties
vm_osdisk = vm_props.storageProfile.osDisk

vmtype = vm_osdisk.osType
osdiskname = vm_osdisk.name

nics = vm.properties.networkProfile.networkInterfaces
nicids = [rsplit(nicid, '/'; limit=2)[2] for nicid in map(nicref->nicref.id, nics)]

File share operations

const resource_group_name = "testresgroup"
const fileshare = "https://mystorage.file.core.windows.net/myshare?restype=share"
success = createShare(ctx, subscription_id, resource_group_name, fileshare, "100", Dict("taname"=>"taval"))
success = setShareProperties(ctx, subscription_id, resource_group_name, fileshare, "150")
success, properties = getShareProperties(ctx, subscription_id, resource_group_name, fileshare)
deleteShare(ctx, subscription_id, resource_group_name, fileshare)

SAS operations

const blob = "https://mystorage.blob.core.windows.net/testblob/myblob.dat"
appendSAS(ctx, subscription_id, resource_group_name, blob)

File blob operations

const storageaccount_url = "https://mystorage.blob.core.windows.net/"
const testcontainer = storageaccount_url * "testcontainer1"

createContainer(ctx, subscription_id, resource_group_name, testcontainer)

listContainers(ctx, subscription_id, resource_group_name, storageaccount_url)

# create blob from string or bytes data
putBlob(ctx, subscription_id, resource_group_name, blob, "BlockBlob";
        block_blob_contents="hello world")

# create blob from a disk file
open(path) do io
   @test putBlob(ctx, subscription_id, resource_group_name, blob, "BlockBlob";
                block_blob_contents=io,
                content_length=filesize(io))
end

listBlobs(ctx, subscription_id, resource_group_name, testcontainer)

getBlob(ctx, subscription_id, resource_group_name, blob)

deleteBlob(ctx, subscription_id, resource_group_name, blob)

Rate card

ratefilter = join(["OfferDurableId eq 'MS-AZR-0003p'",
                   "Currency eq 'USD'",
                   "Locale eq 'en-US'",
                   "RegionInfo eq 'US'"],
                   " and ")
rates = Azure.check_api_response(rate_card_get(
    api(ctx, UsageManagementClient.RateCardApi),
    ratefilter,
    apiver(UsageManagementClient.RateCardApi),
    subscription_id
  ))
