print("Starting script")
SUBSCRIPTION_ID = "mysubscriptionid"
credential = ClientSecretCredential(
    tenant_id='mytenantid,
    client_id='myapplicationid,
    client_secret='myapplicationsecret'
)

compute_client = ComputeManagementClient(
    credential=credential,
    subscription_id=SUBSCRIPTION_ID,
    
)

print("Getting vms")
# List all Virtual Machines in the specified subscription
def list_virtual_machines():
    for vm in compute_client.virtual_machines.list_all():
        print(vm.name)

list_virtual_machines()

        On Windows, Python does not look at the system certificate, it uses its own located at                 ?\lib\site-packages\certifi\cacert.pem.

  1. download the certificate chain from portal.azure.com as *.crt or *pem file
  2. open the file in editor and copy it's content to clipboard. contents will be like below. Copy all of it.
      -----BEGIN CERTIFICATE-----
     bunch of gibbereshin between.
      -----END CERTIFICATE-----
  1. Find your cacert.pem location: from requests.utils import DEFAULT_CA_BUNDLE_PATH; print(DEFAULT_CA_BUNDLE_PATH)
  2. edit the cacert.pem file and paste your domain validation certificate at the end of the file.
  3. Save the file.
